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 arerequired 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.
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).

Note:
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 o f power distribu tion cabinet.

Default = H’0000. Take the setting of CH1 for example:
1. When b0 = 0, the user is allowed to tune CR#18
(OFFSET) and CR#24 (GAIN) of CH1. W hen b0 = 1, the
user is not allo wed to tune CR#18 (OFFSET) and CR#24
(GAIN) of CH1.
2. b1 represents whether the OFFSET/GAIN tuning registers
are latched. b1 = 0 (default, latched); b1 = 1 (non-latched).
3. When b2 = 1, all se ttings will return to default values.
