Instruction Sheet

WARNING

Please carefully read this instruction thoroughly prior to use the DVP-01HC.

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.

INTRODUCTION

2.1

Model Name Explanation and Peripherals

Thank you for choosing DELTA’s PLC DVP series. DVP-01HC high-speed counter input

module could accept 200KHz pulse from external counter. It uses instruction FROM/TO to
read/write the data in module via EH MPU. There are 33 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 modes, such as single-phase mode, two phases mode, 16-bit mode or

32-bit mode, can be designated by CR. The controlled registers are written by instruction TO
via MPU. When wiring, connect 24V, A24+, B24+, P24+, D24+, A12+, B12+, A5+, B5+, P5+
and D5+ to positive potential. In the same way, 0V, A24-, B24-, P24-, D24-, A12-, B12-, A5-,
B5-, P5- and D5- should be connected to negative potential.

Input signal source could be 1-phase or 2-phase encoder and voltage level could be 5V, 12V

and 24V. Besides, it also provides two terminals, PRESET and DISABLE. When terminal
“PRE” is on, the data in CR#10 and CR#11 will be sent to CR#20 and CR#21. That also means
current value of counter will be changed to be factory setting. When terminal “DIS” is on,
“count” operation is disabled.

There are two outputs, YH0 and YH1, in hardware input module of DVP-01HC. When counter

value is equal to the setting, the corresponding output point will activate. The transistors of
output points are independent and isolated.

Wiring

To suit M3.5 screw terminals

Below 6.2

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℃.
