…………………………Thank you for choosing Delta DVP-SA2. DVP-SA2 is a 12-point (8DI + 4DO) PLC MPU, offering various instructions and with 16k steps program memory, able to connect to all DVP-S ries extension modules and high-speed extension modules, including digital I/O (max. 480 I/O points) and analog modules (for A/D, D/A conversion and temperature measurement). 2 points of 100 kHz and 2 points of 10 kHz high-speed pul output satisfy all kinds of applications. DVP-SA2 is small in size and easy to install.
a This instruction sheet only provides introductory information on electrical
specifications, general specifications, installation and wiring. For detailed information on programming and instructions, plea refer to “DVP-SA2 Operation Manual: Programming”. For information about optional peripherals, plea e individual product instruction sheet enclod with DVP-SA2.
a This 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 to open the enclosure) in ca danger and damage on the device may occur.
a DO NOT connect input AC power supply to any of the I/O terminals; otherwi
rious 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. DO NOT touch any terminals when the power is
switched on.

I/O Configuration
Note: The layout of output terminals on DVP-SA2 is different from that on DVP-SA.
Dimension & Installation
Plea install the PLC in an enclosure with sufficient space around it to allow heat dissipation, See [Figure 3].
Direct Mounting: U M4 screw according to the dimension of the product.
DIN Rail Mounting: When mounting the PLC to 35mm DIN rail, be sure to u the retaining clip to stop any side-to-side movement of the PLC and reduce the chance of wires being loo. The retaining clip is at the bottom of the PLC. To cure 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. U 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 plea u only
60/75ºC copper conductor.
2. DO NOT wire empty terminal. DO NOT 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.
Power Supply
The power input of DVP-SA2 is DC. When operating DVP-SA2, plea note the following points:
1. The power is connected to two terminals, 24 VDC and 0 V, and the range of power is
20.4 to 28.8 VDC. If the power voltage is less than 17.5 VDC, 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.
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. (Plea take care of the latched auxiliary relays and registers inside the PLC when doing the programming).
Safety Wiring
Since DVP-SA2 is only compatible with DC power supply, Delta’s power supply modules (DVPPS01/DVPPS02) are the suitable power supplies for DVP-SA2. We suggest you install the protection circuit at the power supply terminal to protect DVPPS01 or
DVPPS02. See the figure below.

Input Point Wiring
There are 2 types of DC inputs, SINK and SOURCE. (See the example below. For detailed point configuration, plea refer to the specification of each model.) DC Signal IN – SINK mode Input point loop equivalent circuit
DC Signal IN – SOURCE mode Input point loop equivalent circuit
Output Point Wiring
