WARNING
This Instruction Sheet only provides descriptions for electrical specifications, general specifications,
installation & wiring, troubleshooting and peripherals. Other detail infromation about programming and
commands is compatible with SA/SC/SX series; please see PLC Application Manual. For more information
about the optional peripherals , please see individual product manual.
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, so as to avoid the hazard to users and the damage to the PLC.
Never connect the AC main circuit power supply to any of the input/output terminals, as it will damage the
PLC. Check all the wiring prior to power up. To avoid any electromagnetic noise, make sure the PLC is
properly grounded
. Do NOT touch terminals when power on.

Installation of the DIN rail
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.
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:

Notes:
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 between 1.95 kg-cm (1.7 in-lbs).
Output Point Wiring
DVP-**-**-11-R
1.
There are two kinds of DVP-SX Series PLC output modules:
Relay and Transistor. For relevant electrical specification,
please refer to the function specification.
2.
Be careful with the connection of the common terminals when
wiring outputs. For example, when wiring DVP12SX11R,
output terminal Y0 uses one common terminal C0, Y1 uses C1,
as shown below:
LOAD
Y0
2. I/O signal wires or power supply should not run through the same multi-wire
cable or conduit. Use Copper Conductor Only, 60/75 °C

RELAY OUTPUT
Power Input Wiring
If the “ERROR” LED of the MPU is not blinking, use RUN/STOP switch or the peripheral devices (HPP or
WPLSoft) to give the RUN command, and the RUN indicator will then be on. If the “RUN” LED is not on, it
indicates that there is no program inside the PLC.
HPP could be utilized to monitor the settings and the registered values of the timer (T), the counter (C) and the
data register (D) during operation, and moreover, to force the output contacts to conduct the On/Off action. If
the ERROR LED is on (but not blinking), it means that the setting of the user’s program has exceeded the
preset time-out limit. At this case, please turn the PLC RUN/STOP switch to STOP, and find out the address
of the time-out program by special data register D1008. ”WDT” instruction can be used to solve the problem.
PLC Input/Output Reaction Time
The total reaction time from the input signal to the output operation is calculated as follows:
Reaction Time = input delay time + program scan time + output delay time
DVP-SX series input power supply is DC input. Please take a note of listed items when operating DVP-SX. Series.
Input delay time
1. Please make sure the power is at terminals 24VDC and 0V (power range is 20.4VDC~28.8VDC). When
voltage is lower than 20.4VDC, PLC will stop operating, all outputs will turn Off and ERROR LED will flash
continuously.

2. If the power-off time is less than 10ms, the PLC still operates unaffectedly. If the power-off 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 operate automatically. (There are latched auxiliary relays and
registers inside of the PLC, please be aware when programming.)

TRIAL RUN
The “POWER” LED at the front of the MPU or the Expansion Units will be lit (in green) if the power is on. If the
indicator is not on when the MPU is powered up, it means that the 24V DC power supply of the PLC is
overloaded. It is thus necessary to remove the wiring on terminals +24V and 24G, and to use a 24VDC power
supply instead. If the ERROR LED is blinking swiftly, it suggests that the +24V power supply of the PLC is
insufficient.
There is also a “BAT.LOW” LED at the front of the MPU. When the LED is on, it indicates that the battery
voltage is insufficient. Please change the batter (within 3 minutes) as soon as possible; otherwise the user
programs and the data in latched area may be lost.

Basic Commands and Application Commands of the PLC:
Isolated circuit: The optical coupler is used to isolate signals
between PLC internal circuits and input modules.
100K
Factory setting: 10 ms. Please refer to the usage of special
register D1020~1021.
Please refer to the usage of special register D1010.
Relay module: 10ms. Transistor module: 20~30us.
Prior to applying power, please verify that the power lines and the input/output wiring are correct. And be
advised not to supply AC110V or AC220V into the I/O terminals, or it might short-circuit the wiring and
would cause direct damage to the PLC.
There is a “POWER” LED at the front of the MPU. When the MPU is powered On, the green LED light will be on.
If the indicator is not on when the MPU is powered up and with the input power being normal, it is an indication
that the PLC is out of order. Please have this machine replaced or have it repaired at a dealer near you.
☼ PLC “RUN” LED
Identify the status of the PLC. When the PLC is in operation, this light will be on, and users could thus use HPP
or the editing program of the ladder diagram to give commands to make the PLC “RUN” or “STOP”.
☼ “ERROR” LED
If incorrect programs are input to the MPU, or that the commands and the components exceed the allowable
range, the indicator will blink. At this moment, the user should check both the error codes saved in the MPU data
register D1004 and the Error Code Table below to correct the programs. The address that the error occurs will
be stored in data register D1137 (the address saved in D1137 is invalid in case of common loop error).
When the ERROR LED is on (not blinking), users should make a judgment from the special relay M1008 of the
MPU. If it is On, it indicates that the execution time of the program loop has exceeded the time-out setting (set by
D1000). Please turn the PLC RUN/STOP switch to STOP, and find out the address of the time-out program by
special data register D1008. ”WDT” instruction can be used to solve the problem. Once program modification is
completed, user can re-download the program of PLC and the ERROR LED will be off. If the ERROR LED is still
keep on, please turn off the power and check if there’s any noise or any conductive invader inside the PLC.
☼ “BAT.LOW” LED
When the battery voltage is low, the “BAT.LOW” LED will be on, and the battery should be replaced as soon as
possible; otherwise the user program and the data in latched area will be lost. (On the unplugged PLC, please
change the battery within 3 minutes to retain the PLC’s internal user programs and data). Choose lithium battery
TDRTL-2150/S. Please refer to the following table for battery life information.

Precision of calendar timer:
At 0°C/32°F, less than –117 seconds error per month.
At 25°C/77°F, less than 52 seconds error per month.
At 55°C/131°F, less than –132 seconds error per month.
☼ “Input” LED
The On/Off signals of the input point could be displayed through the “Input” LED, or the status of the input point
could be monitored through the device monitoring function of HPP.
☼ “Output” LED
Output LED indicates if the output signals are On or Off. Please check the following items when the LED On/Off
indication does not correspond to the commands: 1. Output contacts may be melted and stuck together due to a
short circuit or current overload. 2. Check wiring and verify that the screws are tight.
