Fieldbus: EtherCAT
Auto-configuration of I/O modules
I/O configuration and firmware update via the fieldbus (FoE)
Full support of the modular slice concept via CoE (CANopen over EtherCAT)
Configurable I/O cycle (0.2 to 4 ms)
Synchronization between the fieldbus and X2X Link
EtherCAT is an Ethernet-based fieldbus developed by Beckhoff. This protocol is suitable for both hard and soft real-time requirements in automation technology. In addition to a ring structure, which becomes logically necessary because of the summation frame telegram used, the EtherCAT technology also physically supports topologies such as line, tree, star (limited) and combinations of these topologies. B&R's X20BC80G3 (expandable bus controller module) and X20HB88G0 (standalone junction base module) are available for implementing these topologies.
EtherCAT slave devices take the data designated for them from a telegram as it is passing through the device. Input data is also added to the telegram as it is passing through. The bus controller allows X2X Link I/O modules to be coupled to EtherCAT and operated on any EtherCAT master system. A transition between IP20 and IP67 protection outside of the control cabinet is possible by arranging X20, X67 or XV modules one after the other as needed at distances up to 100 m.
Master systems without FoE (File access over EtherCAT) support require an appropriate configuration tool to transfer the configuration (optional).


20 safe digital inputs 4 pulse outputs Sink circuit Software input filter configurable for each channel This module is equipped with 20 safe digital inputs. It is designed for a nominal voltage of 24 VDC. The module can be used to read various digital signals in safety-related applications up to PL e or SIL 3. The module is equipped with filters that are individually configurable for switch-on and switch-off behavior. The module also provides pulse signals for diagnosing the sensor line. This module is designed for X20 12-pin terminal blocks.

NetTime timestamp: Position change, trigger time
The stepper motor module is used to control up to 2 stepper motors with a nominal voltage of 24 to 38.5 VDC ±25% at a motor current up to 3 A (5 A peak).
In addition, this module has 6 digital inputs that can be used as limit switches or encoder inputs.
Due to the individual adjustment of the coil currents, the motor is only operated with the current it actually needs. This simplifies the selection of the available motors and prevents unnecessary heating. Because this affects energy consumption and thermal load, the effects are positive on the service life of the complete system. Complete flexibility is achieved through the use of independently adjustable holding, boost and nominal current values. The current for microsteps is automatically adjusted to the configured current values.
The automatic motor identification system is an enormous help during standstills. The stepper motor modules can identify the connected motors using their coil characteristics and generate feedback in the form of an analog value. This makes it possible to detect not only wiring errors, but also incorrect motor types being used mistakenly. A stall detection mechanism is integrated to analyze the motor load. Detection of the stall is defined via a configurable threshold. This allows an overload or motor standstill to be detected precisely in many different types of applications.

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.
