X2X Link bus transmitter
For seamless expansion of the system
Up to 100 m segment length
Supply for internal I/O power supply
Operation only on the rightmost slot
The bus transmitter is used for seamless expansion of the X20 system. Stations can be up to 100 m apart.

Bus module for 24 VDC I/O modules
The internal I/O power supply is connected through.
The bus module is the base for all 24 VDC I/O modules. The internal I/O power supply is connected through.

CAN bus interface for serial, remote connection of complex devices to the X20 system
Integrated terminating resistor
In addition to the standard I/O, complex devices often need to be connected. The X20CS communication modules are intended precisely for cases like this. As normal X20 electronics modules, they can be placed anywhere on the remote backplane.

X2X Link bus receiver. Feed for X2X Link and internal I/O supply
Electrical isolation of feed and X2X Link supply
Redundancy of X2X Link supply possible by operating multiple supply modules simultaneously
Operation only on the slot to the far left
The bus receiver is used to connect the X20 System to the X2X Link. The module is equipped with a feed for the X2X Link as well as the internal I/O supply.

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.
