140CRP31200 Schneider Relay Module
140CRP31200 is a Quantum series Ethernet RIO (Remote I/O) master
station module launched by Schneider Electric, designed
specifically for industrial automation control systems. It has 4
Ethernet ports and supports Ethernet IP/Modbus TCP protocol,
enabling efficient communication between PLC and remote I/O devices
as well as distributed I/O devices. It provides core functions such
as I/O scanning, link topology management, remote device
configuration and diagnosis, and supports hot standby function to
ensure that the IP address remains unchanged when switching between
the main and backup modules, ensuring system continuity. It adopts
a daisy chain loop topology structure, supports RSTP protocol,
achieves communication interruption recovery within 50
milliseconds, is compatible with multiple industrial protocols, and
has port mirroring Practical functions such as Service port
diagnosis have passed international certifications such as UL 508,
CE, C-tick, CSA C22.2 42, EN 55011, IEC 61000-4-16, and are
suitable for industrial automation scenarios that require high
reliability, real-time performance, and scalability, such as steel
plants, cement plants, power and water treatment, etc.
