Please read this instruction carefully before use. Switch off the power before wiring. 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.
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.
DO NOT touch any terminal when the power is switched on. DO NOT touch any internal circuit in 1 minute after
the power is switched off.
Make sure the groud terminal is correctly grounded in order to prevent electromagnetic interference.
ENGLISH
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).
