Modbus RTU Protocol, Latching Relay, Multi Isolation Protection Circuits
This is an industrial 8-ch latching relay module controlled via RS485 bus, which can keep the relay state unchanged after power loss. It adopts Modbus RTU protocol, featuring embedded protection circuits such as power isolation, magnetical isolation, and TVS diode, etc. It also comes with an ABS enclosure. The Modbus RTU Relay (C) is very easy to use. Due to its fast communication, stability, reliability, and safety, it is an ideal choice for industrial control equipments and/or applications with high communication requirement.
- Adopts latching relay, the state of the relay can remain unchanged after power loss
- Configurable device address (1~255), multi devices can be cascaded on RS485 bus
- Features flash-on, flash-off function, by passing arguments to the command, it is possible to turn on the relay for a while and then close it automatically
- Onboard unibody power supply isolation, provides stable isolated voltage, needs no extra power supply for the isolated terminal
- Onboard unibody magnetical isolation, allows signal isolation, high reliability, strong anti-interference, low power consumption
- Onboard resettable fuse and TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, provides over-current/over-voltage proof, lightningproof & anti-electrostatic
- Adopts dedicated latching relay driver chip for stronger and more stable driving ability
- Reverse-proof circuit, prevent the circuit from being damaged accidentally by incorrect connection
- High quality relay, contact rating: ≤10A 250VAC/30VDC
- Rail-mounted ABS plastic enclosure, easy to install, safe to use
- 3 LEDs for indicating the MCU status and signal transceiving status

Supports sending Modbus RTU protocol commands via RS485 for relay output control
Multiple protections for safer and more reliable use
Rail-mounted ABS plastic enclosure, easy to install, safe to use
Configurable device address (1~255), multi devices can be cascaded on RS485 bus
In case of many devices are cascaded, or communication distance is quite long, it is necessary to use RS485 repeaters
for reference only, the USB TO RS232/485/TTL converter is Not included
Contact rating of the onboard relay up to 10A 250VAC/30VDC
