Thank you for choosing Delta’s DVP series PLC. The analog input module of
DVP04AD-SL series can read/write the data of analog input module by using
instructions FROM/TO via DVP SV/EH2-L MPU program. The analog input module
receives 16bit digital data of 4 groups from PLC MPU and converts it into 4 points
analog input signal either in voltage or in current. Users can select input from voltage or
current via wiring. Voltage input range is -10V~10VDC (resolution is 312.5μV). Current
input range is -20mA ~ 20mA (resolution is 625nA).
a 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.
a 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.
a 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.
a Tightening torque for I/O terminal block is 1.95 kg-cm (1.7 in-lbs) and please uses
60/75°C copper conductors only.

Terminal of
power module
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
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.
