  • 10 channels high power relays: 10A x 4, 5A x 6
  • Supports IR commands (custom:64, built-in:32) for relay control.
  • NO & NC terminals for each channel
  • Protection circuit for each channel
  • Sequential relay control
  • Supports maximum 5 sets of interlocked relay pairs (e.g. CW/CCW motor control)
  • Power-on values and power failure memory
  • RS-232 and RS-485 serial interface
  • Supports Modbus/RTU protocol (Slave)
  • Modbus Network IDs: 1 ~ 15 (HW); 1 ~ 247 (SW)


IR-310-RM is a 10-channel high power relay module designed for the power control of various appliances. The relay module can switch up to 10 A loads. There are NO/NC switches and protection circuit for each channel. The relays can be controlled independently or sequentially by serial communication with Modbus RTU protocol, as well as by wireless IR remote control. There are also maximum 5 interlocked relay pairs for interlocked switching. The application field can be manual/automatic power switch, light scenario control and energy conservation etc.
