Installation Instructions
Internal integrated range switching jumper device
Support voltage/current acquisition internal switching Users can jumper wires according to their needs to switch the voltage or current acquisition mode Support adjustment range, 0~10V, 0~30V, 0~20mA switch
Internal acquisition mode, range switching technology
Support voltage 0~5V, 0~10V, 0~30V, current 0~20, 4~20ma high-precision acquisition and switching Built-in voltage and current acquisition mode switching jumper device Voltage or current acquisition switch Multiple range switching, acquisition range switching
Support 8 DO outputs
Cooperate with external relay/switch Remote control While supporting the acquisition of analog quantity, the switch linkage The user can set each channel of AI "up/lower limit" linkage operation "DO" When the AI input triggers the "upper/lower limit" value alarm, the DO output will jump immediately. It can also independently control 8 DO signal outputs and control external switches.
Support analog calibration function
When the equipment is affected by factors such as aging, temperature, etc., the accuracy of the analog quantity The user performs secondary calibration through the configuration software to improve the accuracy of the analog quantity Obtain the required accurate analog data
