Description DVP04AD-E2 In industrial automation, many measuring units are transmitted by analog signals. The most frequently adopted range for the signals are voltage -10V ~ 10V and current -20mA ~ 20mA. To use the analog signals as the parameters for PLC operations, you have to convert them into digital values first. For example, the voltage -10V ~ 10V is first converted into values -32,000 ~ +32,000 by an A/D module, and the PLC will read/write the control registers (CR) in the A/D module. The signals sent back to the PLC for operations will be digital K-32,000 ~ K32, 000 Specification Brand name: DeltaProduct name: Delta PLC Analog input ModuleProduct model: DVP04AD...
