Waveshare 24921 Modbus RTU 16-Ch Relay Module, RS485 Interface, With Multiple Isolation Protection Circuits

Description


Features:
1. This product is an industrial-grade 16-channel relay module controlled by RS485 bus, using Modbus RTU protocol, built-in power isolation, ADI magnetic isolation, resettable fuse, TVS diode and other protection circuits, and equipped with ABS case.
2. Modbus RTU 16 channel relay is very easy to use. Due to its fast communication speed, stability, reliability and security, it is ideal for industrial control equipment and/or applications with high communication requirements.
3. Configurable device address (1-255), multiple devices can be cascaded on the RS485 bus
4. It has the function of blinking and blinking. By passing parameters to the command, the relay can be opened for a period of time and then automatically closed
5. On-board integrated power isolation, providing stable isolation voltage, no additional power supply is required at the isolation end
6. Onboard integrated ADI magnetic isolation, which can realize signal isolation, high reliability, strong anti-interference and low power consumption
7. Onboard resettable fuse and TVS (transient voltage suppressor), effectively suppress surge voltage and transient peak voltage in the circuit, provide overcurrent/overvoltage, lightning protection, anti-static
8. On-board optocoupler isolation to prevent the relay from being interfered by the high-voltage circuit
9. On-board dedicated relay driver chip, built-in freewheeling diode protection, stronger and more stable driving capability
10. Anti-reverse connection circuit to prevent accidental damage to the circuit by wrong connection
11. High quality relay, contact rating: ≤10A 250VAC/30VDC
12. Rail-type ABS shell, easy to install and safe to use
13. There are 3 LEDs for indicating MCU status and signal sending and receiving status

Product parameters:
1. Working voltage: 5V
2. Communication interface: RS485
3. Baud rate: 4800, 9600, 19200, 38400, 57600, 115200, 128000, 256000
4. Default communication format: 9600, N, 8, 1
5. Relay channel: 16
6. Contact information: 1NO 1NC
7. Communication protocol: standard Modbus RTU protocol
8. RS485 address: 1-255
9. LED indicator light:
STA: MCU indicator light, it keeps flashing when the MCU is working normally
TXD: TX indicator light, lights up when sending data
RXD: RX indicator light, lights up when receiving data

Packing list:
-Modbus RTU relay 16CH x1
-US Plug 5V 2A power supply (with EU head adapter) x1
