Thank you for choosing Delta DVP-SX2. DVP-SX2 is a 20-point (8DI + 6 DO + 4AI +
2AO) PLC MPU, offering various instructions and is with 16k steps program memory,
able to connect with all Slim series extension models, including digital input/output (max.
480 input/output extension points), analog modules (A/D, D/A transformation and
temperature units) and all kinds of new high-speed extension modules. Its 2-group
high-speed (100kHz) pulse outputs and the one new 2-axis interpolation instructions
satisfy all kinds of applications. DVP-SX2 is small in size and easy to install.
a This instruction sheet provides only information on the electrical specification,

general functions, installation and wiring. For detailed program design and applicable
instructions for DVP-SX2, please refer to “DVP-SX2 Operation Manual:
Programming”. For details on the optional peripheral, please refer to the instruction
sheet enclosed in the package.

a 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 on the PLC.

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 .
DO NOT touch terminals when power on.

 Dimension & Installation

Please install the PLC in an enclosure with sufficient space around it to allow heat
dissipation, as shown in the [Figure 5].

- 3 -

 Direct Mounting: Please use M4 screw according to the dimension of the product.
 DIN 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.

 Wiring

1. Use 22-16AWG (1.5mm) single or multiple core wire
on I/O wiring terminals. See the figure in the right hand
side for its specification. PLC terminal screws should be
tightened to 1.90 kg-cm (1.65 in-lbs) and please use only

60/75ºC copper conductor.

2. DO NOT wire empty terminal and place the I/O signal 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

Since DVP-SX2 is only compatible with DC power supply, Delta power supply modules
(DVPPS01/DVPPS02) are suitable power supplies for DVP-SX2. Users are suggested
to install the protection circuit at the power supply terminal to protect DVPPS01 or
DVPPS02. See the figure below.

 Power Supply

The power input of DVP-SX2 series is DC. When operating DVP-SX2 series, please
note the following points:

1. The power is connected to the two terminals, 24VDC and 0V, and the range of power

is 20.4 ~ 28.8VDC. If the power voltage is less than 20.4VDC, PLC will stop running,
all outputs will go “Off” and ERROR indicator will flash continuously.

2. 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).

 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.)

 Output Point Wiring

1. DVP-SX2 series have three output modules, relay and transistor (NPN/PNP). Be

aware of the connection of shared terminals when wiring output terminals.

2. Output terminals, Y0, Y1, and Y2, of relay models use C0 common port; Y3, Y4, and

Y5 use C1 common port; as shown in the [Figure 9]. When output points are enabled,
their corresponding indicators on the front panel will be on.

3. Output terminals, Y0 ~Y5 of transistor (NPN/PNP) models use UP, ZP common port;

as shown in the [Figure 10].

4. Isolation circuit: The optical coupler is used to isolate signals between the circuit

inside PLC and input modules.
