DELTA DVP04DA-H2 Analog Output Module
Warning
- DVP04DA-H2 is an OPEN-TYPE device. It should be installed in a control cabinet free of airborne dust, humidity, electric shock and vibration. To prevent non-maintenance staff from operating DVP04DA-H2, or to prevent an accident from damaging DVP04DA-H2, the control cabinet in which DVP04DA-H2 is installed should be equipped with a safeguard. For example, the control cabinet in which DVP04DA-H2 is installed can be unlocked with a special tool or key.
- DO NOT connect AC power to any of I/O terminals, otherwise serious damage may occur. Please check all wiring again before DVP04DA-H2 is powered up. After DVP04DA-H2 is disconnected, Do NOT touch any terminals in a minute. Make sure that the ground terminal
on DVP04DA-H2 is correctly grounded in order to prevent electromagnetic interference.
Introduction
- Model Explanation & Peripherals
- Thank you for choosing Delta DVP series PLC. The data in DVP04DA-H2 can be read or written 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.
- You can select voltage or current output by wiring. Range of voltage output: 0V ~ +10V DC (resolution: 2.5mV). Range of current output: 0mA ~ 20mA (resolution: 5μA).

External Wiring 
- Note 1: When performing analog output, please isolate other power wirings.
- Note 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.
- Note 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.
- Note 4: If there is much noise, please connect the terminal FG to the ground terminal.
- Warning: DO NOT wire empty terminals .

CR#0 ~ CR#34: The corresponding parameter addresses H’4032 ~ H’4054 are for users to read/write data by RS-485 communication. When using RS-485, the user has to separate the module with MPU first.
- Function: H’03 (read register data); H’06 (write 1 word datum to register); H’10 (write many word data to register).
- Latched CR should be written by RS-485 communication to stay latched. CR will not be latched if written by MPU through TO/DTO instruction.
