DVP-02HC
1 WARNING
Please carefully read this instruction thoroughly prior to use the DVP-02HC.
Make sure that power is OFF before wiring.
This is an OPEN TYPE PLC. The PLC should be kept in an enclosure away from airborne dust, humidity,
electric shock risk and vibration. Also, it is equipped with protective methods such as some special tools or
keys to open the enclosure, in order to prevent hazard to users or damage the PLC.
Do NOT connect the AC main circuit power supply to any of the input/output terminals, or it may damage the
PLC. Check all the wiring prior to power up.
2 INTRODUCTION
2.1 Model Name Explanation and Peripherals
Thank you for choosing DELTA's PLC DVP series. DVP-02HC high-speed counter input module could accept 2
sets of 200KHz pulse from external counter. It uses instruction FROM/TO to read/write the data in module via EH
MPU. There are 34 Controlled Registers (CR, each register is 16-bit) in each module. 32 bits data consists of
two continuous CRs and allow executing itself after setting CR.
The different counter mode, such as single-phase mode, two phases mode, 16-bit mode or 32-bit mode, can be
designated by CR.
Input signal source could be 1-phase or 2-phase encoder and voltage level could be 24V. Besides, it also
provides two terminals, PRESET and DISABLE. When terminal "PRE" is on, current value of counter will be
changed to be factory setting. When terminal "DIS" is on, "count" operation is disabled. There are two modes,
Sink mode and Source mode, for input wiring.
There are two outputs, YH0(CH0) and YH1(CH1), in hardware input module of DVP-02HC. When counter value
is equal to the setting, the corresponding output will activate. The transistors of outputs are independent and
isolated.

Specification
1. Please use O-type or Y-type terminals for I/O wiring terminals. The specification for
the terminals is as shown on the left. Tighten PLC terminal screws to a torque of 5
to 8 kg-cm (4.3~6.9 in-lbs).
2. I/O signal wires or power supply should not run through the same multi-wire cable
or conduit.
3. Use copper conductor only, 60℃.
