Parameters of ZHT0800

• Introduction​ of ZHT0800

ZHT0800 contains a 485 interface, multiple devices can be cascaded through the 485 bus. Each module can set the address, the address ranges from 1-30. The maximum communication distance of the 485 bus is 1200 meters, and the communication distance can be increased through the 485 relay according to the actual application environment.

Product model: ZHT0800, the product is mainly used to expand the interface of RTU products and does not provide communication functions. Provide 8DO interface and 8 relay outputs.
Features: The relay output is isolated, supports dry and wet node detection, and supports delayed shutdown after the relay is opened, which is simple and convenient to use.
Application: Weather station monitoring, monitoring temperature, temperature, pressure, gas, PM2.5, customs, rainfall and other sensor data.

Working Mode of ZHT0800

1. Linkage Mode

The digital input terminal is connected with a manual switch, such as: a 86-type switch to control the relay output of the corresponding channel to realize manual control and host computer control, that is, dual control, without wiring.

2.Jog Mode

Custom setting on time, automatically turn off after a period of time.
