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.

Programmable logic controllers are ruggedized industrial computers that execute control logic for machine and process automation, handling digital and analog I/O, motion coordination, and network communication in real time across manufacturing and infrastructure environments. PLC Direct supplies programmable logic controllers as an independent supplier, carrying surplus sealed, refurbished, and used hardware for maintenance and replacement in installed automation systems.
Where Are Programmable Logic Controllers Used in Industrial Environments?
Programmable logic controllers are used wherever automated machine or process control requires deterministic, scan-based logic execution across digital and analog field signals. These controllers are installed across virtually every sector of industrial operations, from individual machine control panels to plant-wide distributed automation architectures.
Facilities and operations that depend on programmable logic controllers include:
-
Discrete manufacturing plants running assembly line automation, machine sequencing, and multi-axis motion control.
-
Food and beverage processing facilities managing conveyor systems, batch recipes, and filling line control.
-
Water and wastewater treatment plants controlling pump stations, dosing systems, and distributed process equipment.
-
Automotive and metal fabrication operations requiring high-speed discrete I/O and coordinated production line control.
-
Packaging, material handling, and logistics operations where flexible, modular control architectures support high-mix production environments.
Maintenance engineers and procurement teams sourcing replacement programmable logic controllers depend on the availability of both current-generation and legacy hardware to keep installed systems running without redesigning existing control architectures.
Which Brands of Programmable Logic Controllers Does PLC Direct Stock?
PLC Direct stocks programmable logic controllers across the major control platform brands deployed in installed automation systems worldwide.
-
Siemens SIMATIC S7 series: S7-300 and S7-400 modular controllers confirmed in stock, covering mid-range and high-end machine and process control applications across manufacturing and process industries.
-
Schneider Electric Modicon M340 and M580: Mid-range and high-end PAC platforms for machine and process control, with Modicon Quantum 140CPU series also stocked for larger installed process automation environments.
-
Mitsubishi Electric MELSEC iQ-R, Q Series, and FX5: Controller hardware spanning high-performance iQ-R CPUs, modular Q Series processors, and compact FX5 units for machine control applications across discrete manufacturing.
-
Omron Sysmac NX Series: NX1P2 CPU modules and associated I/O for Omron's machine automation platform, suited to packaging, assembly, and process control installations using EtherCAT and EtherNet/IP communication.
PLC Direct carries programmable logic controllers as surplus sealed, refurbished, and used hardware, giving maintenance teams and procurement managers options across condition grades and budget requirements.
What Should You Know Before Ordering Programmable Logic Controllers?
Hardware condition options: PLC Direct supplies programmable logic controllers in surplus sealed, refurbished, and used condition. Surplus sealed units are factory-sealed stock that has not been previously installed; refurbished controllers 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: Programmable logic controllers are platform-specific, and CPU modules, I/O expansion, power supplies, and communication modules must be matched to the correct rack, backplane, and firmware environment for the installed system. Confirm the CPU part number, series designation, and any firmware or version requirements from existing system documentation before ordering. For legacy platforms such as the SIMATIC S7-300 and S7-400 or Modicon Quantum, verify rack slot and power supply compatibility as part of the identification process.
Warranty: All programmable logic controller 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 programmable logic controller hardware for replacement and maintenance purposes and does not provide system design, programming, or integration services.
