Delta: Analog Output Module (DVP04DA-S)

The D/A Conversion - In industrial automation, many control signals are analog signals. The most frequently adopted range for the signals are voltage 0 ~ 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, data 0 ~ 4,000 in the PLC are converted into voltage 0 ~ 10V by a D/A module. The output voltage can therefore be used for controlling the peripheral analog devices.

The data in DVP02DA (DVP04DA) analog signal output module can be read/written by using FROM/TO instructions in the program of DVP-PLC MPU. There are 49 16-bit control registers in the module. The module receives 2 (4) groups of 12-bit digital data coming from the PLC MPU and converts the digital data into 2 (4) points of analog output signals (voltage or current). You can select voltage output or current output by the wiring. Range for voltage output: 0 ~ 10V (0 ~ 4,000, resolution: 2.5mV). Range for current output: 0 ~ 20mA (0 ~ 4,000, resolution: 5µA).
