Product Overview
The Schneider BMXP3420102CL is a powerful processor module from the Modicon M340 automation platform. Designed for demanding industrial control applications, this module supports up to 1024 discrete I/O in multi-rack configurations and up to 704 discrete I/O in single-rack setups. It requires a separate memory card (not supplied) to operate, making it a cost-effective upgrade path for existing M340 systems. Ideal for replacing older processors or expanding system capacity, the BMXP3420102CL delivers high-speed processing with a Boolean execution time of just 0.12 µs and a system overhead of only 0.7 ms for master tasks.

Integrated Communication & Compatibility
The BMXP3420102CL includes a variety of built-in communication ports: a non‑isolated serial link (RJ45) supporting character mode, Modbus master/slave (RTU/ASCII) on RS232C or RS485, a USB port at 12 Mbit/s, and a CANopen master bus (SUB‑D9). It supports up to 63 CANopen server devices and can handle 2 Ethernet communication modules and 4 AS‑Interface modules. This extensive connectivity ensures seamless integration into existing Modicon M340 architectures and with third‑party devices.
Application Scenarios
This processor module excels in mid‑sized automation tasks such as material handling, packaging lines, and process control. Its fast task execution (0.13 ms for fast tasks, 0.7 ms for master tasks) makes it suitable for applications requiring quick response times. In a multi‑rack configuration, the BMXP3420102CL can manage up to 4 racks and 11 slots, enabling scalable I/O expansion. The built‑in CANopen motion control support (independent axis) further enhances its use in coordinated drive systems.
Selection Guide & Purchasing Advice
Before purchasing the BMXP3420102CL, ensure you have a compatible memory card because the module does not operate without one. Verify that your power supply can deliver the required 90 mA at 24 V DC via the rack. The module is CE, UL, CSA, RCM, EAC, and Merchant Navy certified, and suitable for hazardous locations (Class I Division 2).
