【Overview】

[] RS485 8-Ch Relay Module (D)：Modbus RTU Protocol, Multi Isolation Protection Circuits, Safe & Stable & Reliable

【Features】

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
