………………………………………………………………… ENGLISH …………………………………………………………………

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).

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. 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.

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.

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.

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 terminal on both the power module and A/D module to the system earth 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.
