Smart 32-Ch Relay Module, Modbus RS485 Interface, With Multiple Isolation Protection Circuits
KMOD-RM32 is an industrial 32-ch relay module controlled via RS485 bus, adopts Modbus RTU protocol, built-in protection circuits such as power supply isolation, magnetically isolation, resettable fuse, and TVS diode, etc, It also comes with an ABS case.
Product Features
- Easy to use. Due to its fast communication, stability, reliability, and safety, it is an ideal choice for industrial control equipment’s and/or applications with high communication requirements.
- Configurable device address (1-255), multi devices can 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 magnetically 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, 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: 1QA 250VAC/30VDC Rail-mounted ABS case, easy to install, safe to use
- 3 LEDs for indicating the MCU status and signal transceiving status
