Warning
This instruction sheet provides only information on the electrical specification, general functions, installation and
wiring. The program design and applicable instructions for DVP-EC3 are the same as those applicable for DVP-ES
series. For detailed information, please refer to “DVP-PLC Application Manual: Programming”. For details of the
optional peripheral, please refer to the instruction sheet enclosed in it.
DVP-EC3 series PLC 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.
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.
Introduction
Thank you for choosing Delta DVP-EC3 series programmable logic controller. DVP-EC3 currently offers 10-16
I/O points. To ensure proper installation, operation and maintenance, please read this instruction sheet carefully
and provide users with this instruction sheet before installing DVP-EC3.

1. Use the 12-24 AWG single-core bare wire or the multi-core wire for the I/O wiring, and please use 60/75°C
copper conductor only. The twisting power of the screw for the DVP-EC3 terminal is 3.80 kg-cm (3.30
lb-in) .
2. DO NOT wire empty terminal. DO NOT place the input signal wire and output power wire in the same
wiring circuit.
3. DO NOT drop tiny metallic conductor into DVP-EC3 while screwing and wiring
3.2 Mounting & Installation
Please install PLC in an enclosure with sufficient space around it to allow heat dissipation. For heat
dissipation, make sure to provide a minimum clearance of 50mm between the unit and all sides of the cabinet.
(See the figure.)
How to screw: Please use M4 screw according to the dimension of the product.
How to install DIN rail: PLC can be secured to a cabinet by using the 35mm DIN rail. When mounting PLC to
DIN rail, be sure to use the end bracket to stop any side-to-side movement of it and reduce the change of
wires being loosen. A small retaining clip is at the bottom of it. To secure PLC to DIN rail, place the clip onto
the rail and gently push it up. To remove it, pull the retaining clip down and gently remove it from DIN rail.
3.3 Wiring Notes
Specification & Wiring of Power Supply
The power supply input for DVP-EC3 model is AC input. When operating DVP-EC3, please make sure that:
1. The input voltage should be 100 ~ 240VAC. The power supply should be connected to L and N terminals.
Please note that wiring AC110V or AC220V to +24V output terminal or digital input points will result in
serious damage on it.
2. Use 1.6mm wire (or longer) for the grounding of it.
3. The power shutdown of less than 10ms will not affect the operation of it. However, power shutdown time
that is too long or the drop of power supply voltage will stop the running of it, and all outputs will go “OFF”.
When the power supply turns normal again, DVP-EC3 will automatically return to its operation. (Please be
aware of the latched auxiliary relays and registers inside DVP-EC3 when programming.)
4. For max. output of the +24V power supply output terminal for each model, please refer to the electrical
specification table. DO NOT connect other external power supplies to this terminal. Every input point
requires 5 ~ 7mA to drive (e.g. 16 input points will require 80 ~ 112mA to drive). The +24V input on DVP-
EC3 is only for digital input points; other external loads are not suggested.

Safety Wiring
Since DVP-EC3 controls many devices, actions of any device may affect actions of other devices, and the
breakdown of any one 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, as shown in the figure
below.
