Modbus RTU 16-Ch Relay Module, RS485 Interface, With Multiple Isolation Protection Circuits
Product Description
This product is an industrial 16-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 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 and/or applications with high communication requirements.
Product Features
- Configurable device address (1~255), multi-devices can be cascaded on RS485 bus
- Features flash-on, flash-off functions, by passing an argument to the command, it is possible to turn on the relay for a while and then close it automatically
- Onboard unibody power supply isolation, provides stable isolated voltage, and 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, 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
- Operating Voltage: 5V
- Communication Interface: RS485
- Baudrate: 4800, 9600, 19200, 38400, 57600, 115200, 128000, 256000
- Default Communication Format: 9600, N, 8, 1
- Relay Channels: 16
- Contact Form: 1NO 1NC
- Communication Protocol: Standard Modbus RTU protocol
- RS485 Address: 1~255
- LED Indicators STA: MCU indicator, keep flashing when the MCU normally working TXD: TX indicator, lights up when sending data RXD: RX indicator, lights up when receiving data
