Waveshare Modbus RTU 16-Ch Relay Module is an industrial 16-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 16-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’s and/or applications with high communication requirements.

Features:

1. Configurable device address (1~255), multi devices can be cascaded on RS485 bus
2. Features flash-on, flash-off function, by passing argument to the command, it is possible to turn on the relay for a while and then close it automatically
3. Onboard unibody power supply isolation, provides stable isolated voltage, needs no extra power supply for the isolated terminal
4. Onboard unibody magnetical isolation, allows signal isolation, high reliability, strong anti-interference, low power consumption
5. Onboard resettable fuse and TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, provides over-
6. current/over-voltage proof, lightningproof & anti-electrostatic
7. Onboard Optocoupler isolation, prevent the relay from being interfered by high-voltage circuit
8. Onboard dedicated relay driver chip, with built-in freewheeling diode protection, the driving ability is stronger and more stable
9. Reverse-proof circuit, prevent the circuit from being damaged accidentally by incorrect connection
10. High quality relay, contact rating: ≤10A 250VAC/30VDC
11. Rail-mounted ABS case, easy to install, safe to use
12. 3 LEDs for indicating the MCU status and signal transceiving status

Package Includes:

1 x Modbus RTU Relay 16CH
1 x US plug 5V 2A Power supply (with EU head adapter)
