Warning
This Instruction Sheet only provides descriptions for electrical specifications, general specifications, installation &
wiring. Other detail infromation about programming and intructions is compatible with SA/SX/SC series; please see
PLC Application Manual. For more information about the optional peripherals, please see individual product
instuction shee or “DVP-PLC Application Manual: Special module”.
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. To prevent any electromagnetic noise, make sure the PLC is properly
grounded . Do NOT touch terminals when power on.
Introduction
Thank you for choosing DELTA’s PLC DVP series. The DVP-SA series has a 12-points (8 input points + 4
outputs) PLC main processing unit with multiple instructions for use. It also has an 8K Steps program memory
to connect to every SA/SX/SC series extension unit, including digital I/O (Maximum 128 inpu/128 output
extension points), analog module, etc. for various applications. Its power unit is separated from the MPU for
better space utilization and easier installation.

Installation & Wiring
4.1 PLC Mounting Arrangements and Wiring Notes
Installation of the DIN rail:
The DVP-PLC can be secured to a cabinet by using
the DIN rail that is 35mm
high with a depth of 7.5mm.
When mounting the PLC on the DIN rail, be sure to
use the end bracket to stop any side-to-side motion
of the PLC, thus to reduce the chance of the wires
being pulled loose. At the bottom of the PLC is a
small retaining clip. To secure the PLC to the DIN
rail, place it onto the rail and gently push up the clip.
To remove it, pull down the retaining clip and gently
pull the PLC away from the DIN rail.
As shown on the
right:
When installing the DVP series
PLC, make sure that it is
installed in an enclosure with
sufficient space (as shown
below) to its surroundings so as
to allow heat dissipation.

D > 50 mm
Wiring:
22-16AWG
<1.5mm
1. Please use 22-16AWG (1.5mm) wiring (either single or multiple core) for
I/O wiring terminals. The specification for the terminals is as shown on
the left. PLC terminal screws should be tightened to between1.95 kg-cm
(1.7 in-lbs).
2. I/O signal wires or power supply should not run through the same
multi-wire cable or conduit. Use 60/75°C copper Conductor only.
4.2 Wiring Notes
Environment
1. DO NOT store the PLC in an atmosphere that is dusty, smoky, with metallic debris or corrosive or
flammable gases.
2. DO NOT store the PLC in an environment with high temperature or high humidity.
3. DO NOT install the PLC on a shelf or on an unstable surface.
Power Input Wiring
DVP-SA series input power supply is DC input. Please take a note of listed items when operating DVP-SA
Series.
1. Please make sure the power is at terminals 24VDC and 0V (power range is 20.4 ~ 28.8V DC). When
voltage is lower than 20.4V DC, PLC will stop operating, all outputs will be Off and ERROR LED will flash
continuously.
2. If the power-cut time is less than 10ms, the PLC still operates unaffectedly. If the power-cut time is too
long or the power voltage drops, the PLC will stop operating and all the outputs will be Off. Once the
power is restored, the PLC will return to operation automatically. (There are latched auxiliary relays and
registers inside of the PLC, please be aware when programming.)

Safety Wiring
Since the PLC is used to control numerous devices, motion of either one device could affect the motion of other
devices. Therefore the breakdown of a device would consequently be detrimental to the whole auto control
system, thus the result is dangerous. Please use the recommended wiring below for the power input:

Emergency stop
The machinery must provide a quick manual method disconnecting all system power.
Circuit isolation device (System Power Disconnect)
Utilize the electromagnetic contactor and the relay to be the isolation unit of the
power circuit
to prevent the possible instability of the system when the power is supplied on and off.

Input Point Wiring
The DC power is used for DC input signal.
Two types of DC wiring are used: SINK and SOURCE, defined as follows:
Sink = Current flows into the common terminal S/S Source = Current flows out of common terminal S/S

1. Two types of DVP-SA Series PLC output modules: Relay or Transistor. For the electrical specification,
please refer to the function specification.
2. Please watch out the connection of common terminals while wire the outputs. For example, when wiring
DVP12SA11R, output terminal Y0 uses one common terminal C0, Y1 uses C1, and Y2~Y3 share C2, as
shown below:
