4 digital input channels
4 digital channels, configurable as inputs or outputs
1 universal counter pair (2 event counters, AB counters or up/down counters)
Linear movement generator (A/B, direction/frequency) with up to 2 reference pulses
SSI absolute encoder
NetTime timestamp: Input data, target position, position change, edge change, counter change
This module is a multifunction digital signal processor module. It can be used extremely flexibly for a wide variety of tasks involving digital signal processing or digital signal generation. Two primary example applications include controlling stepper output stages with pulse and direction signals or using as encoder emulation. In this application, for example, frequency inverters or servo axes with the speed follow function can follow a real or virtual master axis.
An additional essential feature is the module's integrated timestamp function. It allows counter ramps curves to be generated virtually independently of bus cycle times during encoder emulation, for example. Only the target counter value and moment when it should be reached are transferred. The module automatically generates the corresponding counter values at the appropriate time, precisely in microsecond resolution and independently of the bus clock.

2 inputs for resistance temperature measurement
For PT100 and PT1000
Configurable sensor type per channel
Direct resistance measurement
Configurable 2- or 3- wire connections per module
Configurable filter time
The module is equipped with 2 inputs for PT100/PT1000 resistance temperature measurement.
This module is designed for X20 6-pin terminal blocks. If needed (e.g. for logistical reasons), the 12-pin terminal block can also be used.

Energy measurement for 120 to 480 VAC
Simultaneous measurement of 2 AC mains networks plus 2 additional voltages
For multifunctional measurement tasks
Intelligent mains synchronization unit
The module has a compact size and combines a power measurement module that has special features with a synchronization unit that is able to meet all demands.
The measurement unit's 3 current inputs are suitable for both X: 1 A and X: 5 A current transformers. Overcurrent resistance and the high resolution of the measurement unit round off its features. For the voltage inputs, the value range can be configured between 480 VAC and 120 VAC.
The area of use includes 4-wire AC networks with a phase voltage up to 480 VAC and 3-wire systems, whereas L2 can be grounded (V-connection). The module can also handle Aron measuring circuits.
The resulting measured values include the pure phase current; line-to-line voltage or phase voltage; the effective, reactive and apparent power parts; the mains frequency; the power factor and much more. In addition, peak values and energy meters are stored on the module in nonvolatile memory. Depending on the configuration, it is also possible to use a digital output as a pulse encoder for an external energy meter.
The synchronization unit doesn't just take the phasing and phase voltage into consideration; integrated intelligence also monitors the rate of change and other parameters, allowing them to influence when the synchronization output is switched. It is also possible to monitor a generator using a large number of additional conditions. A total of 4 voltage inputs provide substantial overall flexibility.
Monitoring functions expand the features of the module. Dependent overcurrent monitoring is included, which utilizes the thermal capacity of the motor/generator to allow short overloads while still providing full protection. The dependent, delayed imbalanced load monitoring used to protect three-phase generator and three-phase networks from imbalanced load can be adapted to the characteristics of different generator types using parameters while taking their special thermal time constants into account.

16 digital inputs Sink connection 1-wire connections Software input filter can be configured for entire module The module is equipped with 16 inputs for 1-wire connections. The module is designed for sink input wiring.

PLC modules are the expansion and signal processing hardware that extend a programmable logic controller's capabilities beyond the base CPU, covering digital and analog I/O, specialty functions, communication interfaces, and power supply modules installed in the controller rack or station. PLC Direct supplies PLC modules as an independent supplier, carrying surplus sealed, refurbished, and used hardware for maintenance and replacement across the major PLC platforms deployed in installed automation systems.
Where Are PLC Modules Used in Industrial Environments?
PLC modules are used wherever a base PLC controller requires additional I/O channels, signal types, or functional capabilities beyond what the CPU alone provides, from local rack expansion to distributed I/O stations across a facility. These components are present in virtually every modular PLC installation, handling field signal acquisition, output control, specialty measurement, and network communication alongside the controller CPU.
Facilities and operations that depend on PLC modules include:
-
Discrete manufacturing plants expanding PLC I/O capacity at machine control panels and distributed field cabinets across production lines.
-
Food and beverage processing facilities adding analog input and output modules for temperature, pressure, and flow measurement in batch and continuous process control.
-
Automotive assembly operations using specialty function modules for high-speed counter inputs, encoder feedback, and motion control coordination.
-
Water and wastewater treatment plants extending PLC I/O across pump station control panels and remote treatment process equipment.
-
Packaging and material handling operations where high channel-count digital I/O modules handle the sensor and actuator density of automated sorting and conveyor systems.
A failed or discontinued PLC module in a production system requires a like-for-like replacement to restore the channel capacity and signal type that the controller program depends on.
Which Brands of PLC Modules Does PLC Direct Stock?
PLC Direct stocks PLC modules across the major controller platforms deployed in installed automation systems worldwide.
-
Siemens SIMATIC S7-1200, S7-1500, and ET 200SP modules: Analog input modules across the SM1231 series, digital I/O modules for S7-1200 and S7-1500 racks, and ET 200SP distributed I/O modules including AI and DI/DQ types with PROFINET interface modules confirmed in stock.
-
Omron CJ Series I/O and special function modules: CJ1W digital input, digital output, and analog I/O modules alongside special function modules including high-speed counter units and expansion I/O control units for installed CJ Series PLC architectures.
-
Schneider Electric Modicon Quantum and M580 I/O modules: Discrete and analog expansion modules for the Modicon Quantum 140-series platform and Modicon M580 BMEP/BMEH series, covering the full range of field signal types used in installed Modicon process and machine control systems.
-
B&R X20 System I/O modules: Digital and analog I/O modules, power supply modules, and interface components within the X20 modular system, used in machine and line automation architectures with POWERLINK communication.
PLC Direct carries PLC modules as surplus sealed, refurbished, and used hardware, giving maintenance teams options across condition grades and budget requirements.
What Should You Know Before Ordering PLC Modules?
Hardware condition options: PLC Direct supplies PLC modules in surplus sealed, refurbished, and used condition. Surplus sealed units are factory-sealed stock that has not been previously installed; refurbished modules have been inspected and tested to confirm operational functionality; used hardware is sourced from decommissioned systems and suits facilities managing lifecycle replacements under budget constraints.
Compatibility and part identification: PLC modules are platform-specific and must be matched to the correct controller series, rack or backplane type, and in some cases, firmware version of the installed CPU. A Siemens S7-1200 signal module, for example, is not compatible with an S7-1500 rack, and ET 200SP peripheral modules require a matched interface module for the network protocol in use. Confirm the full module part number, controller series, and rack slot requirements from the installed system's documentation before ordering.
Warranty: All PLC module hardware purchased from PLC Direct carries a standard 1-year PLC Direct warranty covering defects and functionality, applicable to surplus sealed, refurbished, and used products.
PLC Direct supplies PLC module hardware for replacement and maintenance purposes and does not provide system design, programming, or integration services.
