The M340 processor module has a maximum of 1024 discrete and 256 analog I/O (Modbus or Ethernet). 36 application specific channels, product or component type. The processor module can do monitoring, diagnostic counters Modbus, event counters Modbus, is transparent ready, has 4 CANopen racks and 11 slots. It also has 1024 I/O multirack configuration, 704 I/O single rack configuration, analog I/O processor capacity, 256 I/O multirack configuration and 66 I/O single rack configuration. The Modicon M340 offers in a small form factor flexibility and integrated functions. In the heart of your process, it provides plug-and-play solutions with both Schneider Electric and third party devices. The large capacity of Unity Pro SoCollaborative software will ease and shorten programming and commissioning time. Modicon M340 Programmable Automation Controllers (PACs) are built to suit the needs of the process industry and a wide range of demanding automation applications. Modicon M340 PACs can be used individually, but are also the perfect companion to the Modicon M580. Together they can increase the performance, quality, and the profitability of your machine production. M340 PACs have an all in one CPU. It operates at 7 Kinst/ms. By using a multitasking system, it has reflex time. This PAC is programmed with Unity⢠Pro software. The M340 has a USB port for programming and HMI. Two additional Ethernet, CANopen® or Modbus⢠ports are available as required. The memory can process programming code up to 70 Kinst. Application back up is in a supplied memory card. Additional file storage is available up to 128 MB with FTP access. Additional file storage is available up to 128 MB with FTP access. The M340 range doesnât require a battery. It has extended temperature (-25°C +70°C) and conformal coating for operation in harsh environments. Protection for SI and OEM know how by using a SD card technology. Replace or hot swap I/O modules without stopping process. Configuration change on the fly (CCOTF) is used. No need to stop the process to expand system. FTD/DTM configuration tools for plug and play device integration. This simplifies configuration, commissioning, and maintenance. The M340 range is used in process industries, renewable energy applications (Solar, Wind power, etc.), water and cement applications, in manufacturing, in infrastructures and on machines.

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.
