RTU (Remote Measurement and Control Terminal) is widely used in various industries such as building, HVAC, fire protection, water supply, petrochemical, environmental protection and other industries because of its telemetry, remote signaling, remote adjustment and remote control functions. However, as the control requirements increase, the demand for IO points at the control site also increases, which requires improving the collection capability of on-site IO points without increasing the number of single RTUs.
In response to the above needs, Chengdu Zongheng Intelligent Control has launched four serial port control modules in the ZHT series to realize the IO interface expansion of the RTU controller and data collection of different smart instruments.
This series of products adopts the standard Modbus RTU communication protocol and is suitable for on-site applications of various industrial monitoring. At the same time, it can be easily integrated with third-party configuration software and PLC equipment.
Main application fields of products:
1. Used for IO expansion of input and output contacts in industrial control. It can be connected to PLC to expand the input and input ports of PLC.
2. Controlled through the RS485 bus, each device can be set with 1~255 addresses, allowing multiple devices to work at the same time.
3. It can be used to replace ordinary industrial programmable controller PLC for various control occasions (such as various machine control), with higher cost performance.
4. Can be used for microcontroller system learning and testing; quickly build a complete set of switching control systems, such as lighting control systems, access control systems, motor control systems, valve control systems, etc., and cooperate with configuration software to quickly create beautiful controls interface.
5. It can be used for serial port control of multiple relay outputs, and can be used for real-time monitoring of the status of various switching signals on computers and touch screens, such as real-time monitoring of lights, power switches and other signal applications.
6. Used in various distributed control systems, various remote control systems, and remote IO modules.
7. It can be used for large and medium-sized control projects such as lighting control in buildings and advertisements, power plant control, and automated workshops.
8. It can be used as a peripheral expansion module for industrial control computers to easily achieve external control.
