Modbus RTU 16-Ch Relay Module, RS485 Interface, With Multiple Isolation Protection Circuits

Product Description

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 equipment and/or applications with high communication requirements.

Product Features

• Configurable device address (1~255), multi-devices can be cascaded on RS485 bus
• Features flash-on, flash-off functions, by passing an 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, and 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, lightning proof & anti-electrostatic
• Onboard Optocoupler isolation, prevents the relay from being interfered with 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 prevents the circuit from being damaged accidentally by an incorrect connection
• High-quality relay, contact rating: ≤10A 250VAC/30VDC
• Rail-mounted ABS case, easy to install, safe to use
