YM200-04M 4-Channel Latching Relay Module

High-reliability latching relay module usable as a PLC backplane expansion or standalone Remote I/O. Supports optional CANopen and Modbus protocols. Features 4 independent dual-position latching relays (COM/NO) with 10ms pulse flip excitation, retaining state during power loss with zero steady-state power consumption.

Technical Specifications

Power Supply	Backplane Powered / External 24V Pulse Driver Circuit
I/O Channels	4 Independent High-Capacity Latching Relays (COM / NO Contacts)
Operating Mode	PLC Backplane Slave / Standalone Remote I/O
Fieldbus Protocols	CANopen / Modbus Optional (Supports Standalone Remote I/O Networking)
Serial & Ports	Standalone RS-485 (Modbus RTU slave supported)
Network & Ethernet	CAN Fieldbus interface (CANopen Remote I/O supported)
Backplane Bus	Supports CANopen / Modbus / CAN 2.0, standalone Remote I/O & backplane cascade
Selection Guide	Can be used as standalone Remote I/O, supporting optional CANopen and Modbus protocols. Ideal for solar pumping stations, unattended field sites, and memory valve control where state must survive power drops.

Application Scenarios
