non-latched Explanations: 1. When performing analog output, please isolate other power wirings. 2. 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. 3. Please connect the terminal on both the power modules and DVP04DA-H2 to the system earth point and ground the system contact or connect it to the cover of power distribution cabinet. 4.

http://www.delta.com.tw/industrialautomation/ 5011651101-D2E1 9 DVP04DA-H2 is an OPEN-TYPE device 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 to open the enclosure) in case danger and damage on the device may occur. 9 DO NOT connect 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. 9 DO NOT tough any terminal when the power is switched on.

DO NOT touch any internal circuit in 1 minute after the power is switched off. 1.1 Model Explanation & Peripherals ™ Thank you for choosing Delta DVP series. DVP04DA-H2 is able to read and write data of DVP04DA-H2 analog signal output modules through FROM/TO instructions given by the program of DVP-EH2 series MPU. The analog signal output module receives 4 groups of 12-bit digital data from PLC MPU and converts the data into 4 points of analog signals for output in either voltage or current. 2007-01-15 ™ The user can select voltage or current output by wiring. Range of voltage output: 0V ~ +10VDC (resolution: 2.5mV). Range of current output: 0mA ~ 20mA (resolution: 5μA).

Read CR#24 of special module No.0 into D0 and CR#25 into D1. Only 2 groups of data is read at Use 32-bit instruction DTO to write the content in D11 and D10 into CR#7 and CR#6 of special module No.0. Only 1 group of data is written in at a time (n = 1). 1. : The No. of special modules connected to PLC MPU. No. 0 is the module closest to te MPU. Maximum 8 modules are allowed to connected to a PLC MPU and they will not occupy any I/O points. 2. : CR#. CR (control register) is the 49 16-bit memories built in the special module, numbered in decimal as #0 ~ #48. All operation status and settings of the special module are contained in the CR. 1.

When M1083 = Off, during the execution of FROM/TO instruction, all external or internal interruption subroutines will be forbidden. The interruptions are allowed only after FROM/TO instruction finishes its execution. FROM/TO instruction can also be used in an interruption subroutine. 2. When M1083 = On and an interruption signal occurs during the execution of FROM/TO instruction, the interruption will be processed first (with a 100us delay) and the execution of FROM/TO will be stopped. After the interruption subroutine finishes its execution, the program will jump to the next instructio of FROM/TO. FROM/TO cannot be used in an interruption subroutine.
