【Overview】

[] 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.

【Features】

[] 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
