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

Configurable device address (1~255), multi devices can be cascaded on RS485 bus
Features flash-on, flash-off function, by passing 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 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
Onboard Optocoupler isolation, prevent the relay from being interfered by high-voltage circuit
Adopts dedicated relay driver chip, with built-in flyback diode protection, for stronger and more stable driving ability
Supports passive and active digital input, with bi-directional optocoupler isolation, built in debouncing algorithm. The relay supports digital input linkage control or toggle control
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
Multiple LEDs for indicating the MCU status and signal transceiving status

Primary function

Supports reading digital input by sending Modbus RTU protocol commands via RS485 for relay output control

Hardware Analysis

Multiple protections for safer and more reliable use

Digital Input

Supports passive (dry contact) and active (wet contact) digital input, with bi-directional optocoupler isolation

Interfaces & Indicators

With Multiple LED Indicators, Easy To Monitor The Operating Status

Multiple modes for various automation scenarios

Supports multiple relay control modes, each channel supports independent control mode setting

RS485 Communication

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

Relay connection

Contact rating of the onboard relay up to 10A 250VAC/30VDC Directly controlling 220VAC home appliances, or devices below 30VDC

Enclosure Design

Rail-mounted ABS plastic enclosure, easy to install, safe to use
