………………………………………………………………… ENGLISH ……………………………………………………………………
Thank you for choosing Delta DVP-SS2 series PLCs. DVP-SS2 series PLCs include
one 12-point PLC, two 14-point PLCs, and three 28-point PLCs. A DVP-SS2 series PLC
provides various instructions, and the size of the program memory in it is 8k steps. It is
able to connect to all DVP-S series extension modules, including digital I/O (max. 480
I/O points) and analog modules (for A/D, D/A conversion and temperature
measurement). 4 groups of high-speed (10kHz) pulse output satisfy all kinds of
applications. DVP-SS2 is small in size, and can be install easily. Users do not have to
install any batteries in DVP-SS2 series PLCs. The PLC programs and the latched data
are stored in the flash memories.
EN DVP-SS2 is an OPEN-TYPE device. It should be installed in a control cabinet
free of airborne dust, humidity, electric shock and vibration. To prevent
non-maintenance staff from operating DVP-SS2, or to prevent an accident from
damaging DVP-SS2, the control cabinet in which DVP-SS2 is installed should be
equipped with a safeguard. For example, the control cabinet in which DVP-SS2 is
installed can be unlocked with a special tool or key.
EN DO NOT connect AC power to any of I/O terminals, otherwise serious damage
may occur. Please check all wiring again before DVP-SS2 is powered up. After
DVP-SS2 is disconnected, Do NOT touch any terminals in a minute. Make sure
that the ground terminal on DVP-SS2 is correctly grounded in order to
prevent electromagnetic interference.
FR DVP-SS2 est un module OUVERT. Il doit être installé que dans une enceinte
protectrice (boitier, armoire, etc.) saine, dépourvue de poussière, d’humidité, de
vibrations et hors d’atteinte des chocs électriques. La protection doit éviter que
les personnes non habilitées à la maintenance puissent accéder à l’appareil (par
exemple, une clé ou un outil doivent être nécessaire pour ouvrir a protection).
FR Ne pas appliquer la tension secteur sur les bornes d’entrées/Sorties, ou l’appareil
DVP-SS2 pourra être endommagé. Merci de vérifier encore une fois le câblage
avant la mise sous tension du DVP-SS2. Lors de la déconnection de l’appareil,
ne pas toucher les connecteurs dans la minute suivante. Vérifier que la terre est
bien reliée au connecteur de terre afin d’éviter toute interférence
électromagnétique.

Note: The layout of output terminals on DVP-SS2 is different from that on DVP-SS series.
Dimension & Installation
Please install the PLC in an enclosure with sufficient
space around it to allow
heat dissipation, See [Figure 3].

Direct Mounting: 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 re
duce 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
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.
22-16AWG
< 1.5mm
1. DO NOT wire empty terminal. DO NOT place the I/O signal cable in the same wiring
circuit.
2.
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.
Power Supply
The power input of DVP-SS2 is DC. When operating DVP-SS2, please note the
following points:
1. The power is connected to two terminals, 24VDC and 0V, and the range of power is
20.4 ~ 28.8VDC. If the power voltage is less than 20.4VDC, the PLC will stop running,
all outputs will go “Off”, and the ERROR indicator will start to blink continuously.
2. The power shutdown for less than 10ms will not affect the operation of the PLC.

- 5 -
However, the 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 the operation. (Please take care of the
latched auxiliary relays and registers inside the PLC when doing the programming).
Safety Wiring
Since DVP-SS2 is only compatible with DC power supply, Delta’s power supply modules
(DVPPS01/DVPPS02) are the suitable power supplies for DVP-SS2. We suggest you
install the protection circuit at the power supply terminal to protect DVPPS01 or
DVPPS02. See the figure below.

Output Point Wiring
1. DVP-SS2 has two output modules on it, relay and transistor. 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. See [Figure 7]. When the output points are enabled, their
corresponding indicators on the front panel will be on.

3. The output terminals Y0~Y5, , Y0~Y13 of the transistor (NPN) model are connected
to the common terminals UP and ZP. See [Figure 8a]. The output terminals Y0~Y3,
Y0~Y13 on the transistor (PNP) model are connected to the common terminals UP
and ZP. See [Figure 8b].
4. Isolation circuit: The optical coupler is used to isolate signals between the circuit
inside PLC and input modules.

The output of the transistor model is “open collector”. If Y0/Y1 is set to pulse output, the
output current has to be bigger than 0.1A to ensure normal operation of the model.
