Description
Description
Modbus RTU protocol, multi-isolation protection circuits, safe, stable and reliable
This product is a 16-channel industrial relay module controlled via RS485 bus, adopts Modbus RTU protocol, built-in protection circuits such as power supply isolation, ADI magnetic isolation, resettable fuse and TVS diode , etc. It also comes with an ABS case.
The 16-channel Modbus RTU relay is very easy to use. Due to its fast communication, stability, reliability and security, it is an ideal choice for industrial control equipment and/or applications with high communication requirements.
- Configurable device address (1~255), multiple devices can be cascaded on RS485 bus
- Has a flash-on, flash-off function, by passing an argument to the command it is possible to turn on the relay for a certain time and then automatically close it
- Built-in unibody power isolation, provides stable isolated voltage, requires no additional power supply for the isolated terminal
- Built-in ADI unibody magnetic isolation, achieves signal isolation, high reliability, strong anti-interference, low power consumption
- Built-in resettable fuse and TVS (Transient Voltage Suppressor), effectively suppress surges and transient voltage spikes in the circuit, provide protection against overcurrent/surge, lightning and electrostatic
- On-board optocoupler isolation, prevents the relay from being interfered by high voltage circuit
- Built-in dedicated relay driver chip, with built-in freewheeling diode protection, driving ability is stronger and more stable
- Anti-reverse circuit, prevents the circuit from being accidentally damaged by incorrect connection
- High quality relay, contact rating: ≤10A 250VAC/30VDC
- Rail mounted ABS enclosure, easy to install, safe to use
- 3 LEDs to indicate MCU status and signal transmission status
