a This Instruction Sheet only provides descriptions for electrical specifications, general
specifications, installation & wiring. Other detail infromation about programming and
intructions, please see “DVP-PLC Application Manual: Programming”. For more
information about the optional peripherals, please see individual product instuction
sheet or “DVP-PLC Application Manual: Special I/O Modules”.
a DVP-EH3 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
are required for operating the enclosure) in case danger and damage on the device
may occur.
a 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. To prevent any
electromagnetic noise, make sure the PLC is properly grounded
terminals when power on.

Installation
Please install the PLC in an enclosure with sufficient space
around it to allow heat dissipation, as shown in the figure.
yDirect Mounting: Please use M4 screw according to the
dimension of the product.
yDIN Rail Mounting: When mounting the PLC to 35mm DIN
rail, be sure to use the retaining clip to stop any side-to-side movement
of the PLC and reduce the chance of wires being loose. The retaining
clip is at the bottom of the PLC. To secure the PLC to DIN rail, pull
down the clip, place it onto the rail and gently push it up. To remove the
PLC, pull the retaining clip down with a flat screwdriver and gently
remove the PLC from DIN rail, as shown in the figure.

2. DO NOT wire empty terminal. DO NOT place the input signal cable and output
power cable in the same wiring circuit.
3. DO NOT drop tiny metallic conductor into the PLC while screwing and wiring. Tear
off the sticker on the heat dissipation hole for preventing alien substances from
dropping in, to ensure normal heat dissipation of the PLC.
Safety Wiring
In PLC control system, many devices are controlled at the same time and actions of any
device could influence each other, i.e. breakdown of any device may cause the
breakdown of the entire auto-control system and danger. Therefore, we suggest you
wire a protection circuit at the power supply input terminal. See the figure below.

Power Supply
The power input type for DVP-EH3 series is AC input. When operating the PLC, please
note the following points:
1. The input voltage should be current and its range should be 100 ~ 240VAC. The
power should be connected to L and N terminals. Wiring AC110V or AC220V to +24V
terminal or input terminal will result in serious damage on the PLC.
2. The AC power input for PLC MPU and I/O modules should be ON or OFF at the
same time.
3. Use wires of 1.6mm (or longer) for the grounding of PLC MPU.
4. The power shutdown of less than 10 ms will not affect the operation of the PLC.
However, power shutdown time that is too long or the drop of power voltage will stop
the operation of the PLC and all outputs will go OFF. When the power returns to
normal status, the PLC will automatically resume operation. (Care should be taken
on the latched auxiliary relays and registers inside the PLC when programming).
- 4 -
5. The +24V output is rated at 0.5A from MPU. DO NOT connect other external power
supplies to this terminal. Every input terminal requires 6 ~ 7mA to be driven; e.g. the
16-point input will require approximately 100mA. Therefore, +24V terminal cannot
give output to the external load that is more than 400mA.
Input Point Wiring
There are 2 types of DC inputs, SINK and SOURCE. (See the example below. For
detailed point configuration, please refer to the specification of each model.)

Wiring of Differential Input
X0 ~ X1 and X4 ~ X5 of DVP32EH00M3 are all high-speed input circuit and others are
DC24V input. The working frequency of high-speed input circuit can reach up to 200kHz
and is mainly for connecting to differential (double-wire) LINE DRIVER output circuit.

BAT.LOW indicator
BAT.LOW indicator will be on when the battery is in low voltage. When this happens,
change the battery as soon as possible in case your program and data saved in the
latched area will be lost.
After the power is switched off, the data in the latched area are stored in SRAM memory
and its power is supplied by the battery. Therefore, when the battery is in low voltage
and the power-off has been lasted for more than 1 minute, the data in the latched area
will be lost. If you need to permanently save the data in the latched area in the program
and device D, refer to “Flash ROM permanently saved and recover mechanism” as
stated below.
Permanently saved mechanism
You can use WPLSoft (Options -> PLC<=>Flash) to indicate whether to permanently
store the data in the latched area in Flash ROM memory (new indicated data will replace
all data previously saved in the memory).
Recover mechanism
If the battery is in low voltage (before the power is switched off when the BAT.LOW
indicator is on) and the power is off for more than 1 minute, PLC will automatically
restore the data in the latched area in the program and device D of Flash ROM into
SRAM memory next time when it is re-powered.
