Modbus RTU 32-Ch Relay Module, RS485 Interface
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
