Delta: Analog I/O Modules (DVP06XA-E2)

Mixed Analog Input/Output Module | DVP-ES2 Series

The A/D and D/A Conversion - In industrial automation, many measuring units are transmitted by analog signals. The most frequently adopted range for t he signals are voltage -10 ~ +10V and current -20 ~ +20mA. To use the analog signals as the parameters for PLC operations, you have to convert them into digital values first. Furthermore, many control signals are analog signals. The most frequently adopted range for the signals are voltage -10V ~ +10V and current 0 ~ 20mA. Therefore, the data in the PLC have to be converted into analog signals for controlling the peripheral devices. For example, the voltage -10 ~ 10V is first converted into values -32,000 ~ +32,000 by an XA module, and the PLC will read/write the control registers (CR) in the XA module. The signals sent back to the PLC for operations will be digital K-32,000 ~ K32,000. In addition, data -32,000 ~ +32,000 in the PLC are converted into voltage -10V ~ +10V by an XA module. The output voltage can therefore be used for controlling the peripheral analog devices.

The data in DVP06XA-E2 mixed analog input/output module receives external 4 points of analog input signals (voltage or current) and converts them into 16-bit digital signals. For the analog signal output, DVP06XA-E2 receives 2 groups of 16-bit digital data coming from the PLC MPU and converts the digital data into 2 points of analog output signals (voltage or current). The MPU can read/write the data in the module by using FROM/TO instructions or D9900~D9999 in the program. For the analog signal input, you can select voltage input or current input by the wiring. Range for voltage input: ±10V (±32,000). Range for current input: ±20mA (±32,000). For the analog signal output, you can select voltage output or current output by the wiring. Range for voltage output: ±10V (±32,000). Range for current output: 0mA ~ 20mA (0 ~ +32,000).
