This is an industrial 8-ch relay module controlled via RS485 bus, utilizing Modbus RTU protocol. It features embedded protection circuits such as power isolation, ADI isolation, and TVS diode, etc. It also comes with an ABS enclosure.

Configurable device address (1~255), multi-devices can be cascaded on RS485 bus
Features flash-on, flash-off function, bypassing an argument 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 ADI isolation, allows signal isolation, high reliability, strong anti-interference, low power consumption
Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightning-proof & anti-electrostatic
Onboard Optocoupler isolation, prevent the relay from being interfered with by a high-voltage circuit
Reverse-proof circuit, prevent the circuit from being damaged accidentally by incorrect connection
 relay, contact rating: ≤10A 250VAC/30VDC
Rail-mounted ABS  enclosure, easy to install, safe to use
3 LEDs for indicating the MCU status and signal transceiving status

Package Includes:
1 x Modbus RTU Relay

1 x Power adapter US plug 5V/2A 5.5/2.1

1 x Power adapter EU head
