RS485 16-ch Relay Module

Modbus RTU Protocol, Multi Isolation Protection Circuits, Safe & Stable & Reliable

Features at a glance

This product is an industrial 16-ch relay module controlled via RS485 bus, adopts Modbus RTU protocol, built-in protection circuits such as power supply isolation, magnetical isolation, resettable fuse, and TVS diode, etc. It also comes with an ABS case.

The Modbus RTU 16-Ch Relay 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 requirements.

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
Onboard dedicated relay driver chip, with built-in freewheeling diode protection, the driving ability is stronger and more stable
Reverse-proof circuit, prevent the circuit from being damaged accidentally by incorrect connection
High quality relay, contact rating: ≤10A 250VAC/30VDC
Rail-mounted ABS case, easy to install, safe to use
3 LEDs for indicating the MCU status and signal transceiving status
