INTRODUCTION

Modbus RTU 16-Ch Relay Module, RS485 Interface, With Multiple Isolation Protection Circuits, Industrial-Grade, Rail-Mount Case

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, ADI 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 ADI 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
