Product Description

Product Overview

● The relay module is a device used to receive input signals and output power signals, enabling the opening and closing of circuits.
● The relay module is also known as a terminal relay or relay module.
● It serves as an intermediate relay module for connecting controllers such as PLCs and loads such as solenoid valves.
● The relay module functions as a signal amplifier and isolator in the circuit.

Product Features

● Uses Omron miniature relays (G5NB-1A-E) with a compact design to save space.
● Uses DIN rail mounting method.
● Each relay has an independent coil and independent contacts for one-to-one control, supporting PLC output (NPN/PNP).
● Includes shorting bars for easy common wiring.
● The actuator coil terminal is equipped with an LED operation indicator, flyback protection, and surge protection.
● The relay uses a pull-release latch for easy maintenance.

Precautions

· The input terminal has polarity; be sure to connect it correctly.
· Before connecting, please confirm the device specifications.
· Do not operate while powered.
· Operating environment: -40°C to +80°C, non-vacuum, non-freezing conditions, 35–85% RH
