Core functions and advantages

High precision signal acquisition and conversion

The analog input adopts a 16 bit AD conversion chip, which has high acquisition accuracy and can accurately capture small signal changes of the sensor (such as pressure fluctuations of 0.01MPa); Simultaneously equipped with signal filtering function, it can filter out high-frequency interference signals in industrial sites (such as peak pulses generated by motor start stop), ensuring the authenticity and reliability of data transmitted to the control system, providing a foundation for precise control.

Compatible with multiple types of signals and highly adaptable

It supports both analog and digital input/output, and is compatible with multiple signal specifications (such as 0-10V, 4-20mA voltage/current signals, PNP/NPN digital signals). It can connect sensors and actuators of different brands and types without the need for additional adaptation modules, greatly reducing system integration complexity and saving equipment procurement costs.

Flexible communication, easy integration

Supports two mainstream industrial communication protocols, Modbus RTU/TCP, and can seamlessly interface with ABB AC500 PLC, Siemens S7-1200/1500 PLC, Rockwell Micro800 series PLC, and various industrial upper computers (such as WinCC, Kingview). Whether it is short-range device networking (RS-485 bus, maximum transmission distance of 1200 meters) or long-distance data exchange (Ethernet, cross workshop communication can be achieved with switches), stable data transmission can be achieved.

Convenient configuration and diagnosis

Support parameter configuration through upper computer software (such as ABB Control Builder, Modbus debugging tool), which can flexibly set signal range, alarm threshold, communication parameters, etc; At the same time, it has built-in fault self diagnosis function, which can monitor the power supply, communication, and signal acquisition status of the module in real time. If there are abnormalities such as signal exceeding the range or communication interruption, it will alarm through the indicator light and record the fault code, making it easy for engineers to quickly locate the cause of the fault and shorten maintenance time.

Industrial grade stability, strong durability

By using industrial grade components such as high-temperature resistant capacitors and vibration resistant connectors, and undergoing rigorous tests such as high and low temperature cycling and vibration impact, it can withstand harsh environments in industrial sites (such as production lines with continuous vibration and metallurgical workshops with high dust); And the module has overvoltage and overcurrent protection functions. When the input voltage is abnormal or the output load is short circuited, the circuit can be automatically cut off to protect the module and external equipment from damage.

Typical application scenarios
