Working Principle

Signal Acquisition: Receives signals from on-site sensors and devices through analogue input channels and digital input channels. The analogue input signals are converted into digital signals after amplification, filtering and A/D conversion; the digital input signals are directly transmitted to the control circuit inside the module after optoelectronic isolation.

Signal processing and transmission: the collected signals are processed and analysed inside the module, and the corresponding control signals are generated according to the preset control logic and algorithm. The processed signals are transmitted to the control system or other devices through the communication interface to achieve the monitoring and control of industrial processes.

Signal output: According to the instructions of the control system, the corresponding control signals are output to the on-site equipment through the analogue output channel and digital output channel. The analogue output signals are converted into analogue signals after D/A conversion, amplification and other processing; the digital output signals are processed by the driver circuit to directly control the actions of relays, contactors and other devices.
