Modbus RTU 32-Ch Relay Module, RS485 Interface, With Multiple Isolation Protection Circuits, Industrial-Grade, Rail-Mount Case
RS485 32-ch Relay Module

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

Features at a glance

This product is an industrial 32-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 32-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, it is possible to turn on the relay for a while and then close it automatically via the command
  • Onboard voltage regulator chip, supports 7~36V wide voltage power supply
  • 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
Specifications

Onboard multiple isolation protection circuit

Multiple protections, more safe and reliable

Rail-mount case design

Rail-mounted ABS protective enclosure, easy to install, safe to use

RS485 Communication

Configurable device address (1~255), multi devices can be cascaded on RS485 bus
In case of many devices are cascaded, or the communication distance is quite long,
it is necessary to use RS485 repeaters

* for reference only, the USB to RS485 is NOT included.

Relay connection

Contact rating of the onboard relay up to 10A 250VAC/30VDC
Directly controlling 220VAC home appliances, or devices below 30VDC
