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, 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 equipment and/or applications with high communication requirements.
Applications:
- Industrial Control
- Smart Home
- Smart Agriculture
- Breeding and Farming
Features:
- Configurable device address (1~255), multi-devices can be cascaded on RS485 bus
- Features flash-on, and flash-off functions, it is possible to turn on the relay for a while and then close it automatically via the command
- The onboard voltage regulator chip supports a 7~36V wide voltage power supply
- Onboard unibody power supply isolation, provides stable isolated voltage and needs no extra power supply for the isolated terminal
- Onboard unibody 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
- 3 LEDs for indicating the MCU status and signal transceiving status
