Delta DVP Series, DVP04AD-E2 Manual

Introduction

Thank you for choosing Delta's DVP series PLC. DVP04AD-E2 analog input module receives external 4 points of analog input signals (voltage or current) and converts them into 16-bit digital signals. You can select voltage input or current input by the wiring. In addition, you can access the data in the module by applying FROM/TO instructions or read the average value of channels directly by using MOV instruction (Please refer to allocation of special registers D9900 ~ D9999).

  • This instruction sheet provides only information on the electrical specification, general functions, installation and wiring. For detailed program design and applicable instructions, please refer to "DVP-ES2 Operation Manual: Modules". For details of the optional peripheral, please refer to the instruction sheet enclosed in the package.
  • This is an OPEN TYPE I/O module and therefore should be installed in an enclosure free of airborne dust, humidity, electric shock and vibration. The enclosure should prevent non-maintenance staff from operating the device (e.g. key or specific tools are required for operating the enclosure) in case danger and damage on the device may occur.
  • DO NOT connect the input AC power supply to any of the I/O terminals; otherwise serious damage may occur. Check all the wiring again before switching on the power. Make sure the ground terminal is correctly grounded in order to prevent electromagnetic interference.

Note 1: When performing analog input, please isolate other power wirings.
Note 2: When the A/D module is connected to current signals, make sure you short-circuit "V+" and "I+" terminals.
Note 3: If the noise is too significant, please connect FE to the grounding terminal.
Note 4: Please connect the terminal on both the power module and A/D module to the system earth point and ground the system contact or connect it to the cover of power distribution cabinet.
Note 5: If the ripples at the loaded input terminal are too significant that causes noise interference on the wiring, connect the wiring to 0.1 ~ 0.47μF 25V capacitor.

Explanation on Special Registers D9900~D9999

When DVP-ES2 MPU is connected with modules, registers D9900~D9999 will be reserved for storing values from modules. You can apply MOV instruction to operate values in D9900~D9999.
When DVP-ES2 MPU is connected with DVP04AD-E2, the configuration of special registers is as below:

Module #0 Module #1 Module #2 Module #3 Module #4 Module #5 Module #6 Module #7 Description
D1320 D1321 D1322 D1323 D1324 D1325 D1326 D1327 Model Code
D9900 D9910 D9920 D9930 D9940 D9950 D9960 D9970 CH1 average input value
D9901 D9911 D9921 D9931 D9941 D9951 D9961 D9971 CH2 average input value
D9902 D9912 D9922 D9932 D9942 D9952 D9962 D9972 CH3 average input value
D9903 D9913 D9923 D9933 D9943 D9953 D9963 D9973 CH4 average input value

Note 1: D9900 ~ D9999 are average input values of CH1 ~ CH4 and the sampling range is K1 ~ K100. When the sampling range is set to K1, the values displayed in D9900~D9999 are current values. You can use:

  1. ES_AIO Configuration Function of WPLSoft or
  2. FROM/TO instructions (CR#8 ~ CR#11) to set the sampling range as K1.

Adjust A/D Conversion Curve

Users can adjust the conversion curves according to the actual needs by changing the Offset value (CR#28 ~ CR#31) and Gain value (CR#34 ~ CR#37).
Gain: The corresponding voltage/current input value when the digital output value = 16,000.
Offset: The corresponding voltage/current input value when the digital output value = 0.
