Modbus RTU 32-Ch Relay Module RS485 Interface Built-in Protection Circuits Industrial-Grade with ABS Case

Features 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 Package include 1. Modbus RTU Relay 32CH x1
