Instruction Sheet

DVP-SX2 Programmable Logic Controllers

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 it can be installed easily.
  Users do not have to install any batteries in DVP-SX2 series PLCs. The PLC programs and the latched data are stored in the high-speed flash memories.
    DVP-SX2 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-SX2, or to prevent an accident from damaging DVP-SX2, the control cabinet in which DVP-SX2 is installed should be equipped with a safeguard. For example, the control cabinet in which DVP-SX2 is installed can be unlocked with a special tool or key.
  DO NOT connect AC power to any of I/O terminals, otherwise serious damage may occur. Please check all wiring again before DVP-SX2 is powered up. After DVP- SX2 is disconnected, Do NOT touch any terminals in a minute. Make sure that the ground  terminal **** on DVP-SX2 is correctly grounded in order to prevent electromagnetic interference.

I/O Configuration

Dimension & Installation

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

• 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 26-16AWG (0.4~1.2mm) 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 2.0 kg-cm (1.77 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.

1. AC power supply:100 ~ 240VAC, 50/60Hz
2. Breaker
3. Emergency stop: This button cuts off the system power supply when accidental emergency takes place.
4. Power indicator
5. AC power supply load
6. Power supply circuit protection fuse (2A)
7. DVPPS01/DVPPS02
8. DC power supply output: 24VDC, 500mA
9. DVP-PLC (main processing unit)
10. Digital I/O module

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. The output terminals Y0~Y5 of the transistor (NPN) model are connected to the common terminals UP and ZP. See [Figure 10a]. The output terminals Y0~Y5 on the transistor (PNP) model are connected to the common terminals UP and ZP. See [Figure 10b].
4. Isolation circuit: The optical coupler is used to isolate signals between the circuit inside PLC and input modules.
   Relay (R) output circuit wiring

1. DC power supply

2. Emergency stop: Uses external switch

3. Fuse: Uses 5~10A fuse at the shared terminal of output contacts to protect the output circuit

4. Transient voltage suppressor (SB360 3A 60V): To extend the life span of contact.
   1. Diode suppression of DC load: Used when in smaller power (Figure 12a)
   2. Diode + Zener suppression of DC load: Used when in larger power and frequent On/Off (Figure 12b)

5. Incandescent light (resistive load)

6. AC power supply

7. Manually exclusive output: For example, Y3 and Y4 control the forward running and reverse running of the motor, forming an interlock for the external circuit, together with the PLC internal program, to ensure safe protection in case of any unexpected errors.

8. Absorber: To reduce the interference on AC load (Figure 13)

Transistor (T) output circuit wiring

1. DC power supply

2. Emergency stop

3. Circuit protection fuse

4. TVS diode: Prolongs the contacts’ durability for greater service life.
   1. Diode suppression: Used when in smaller power (Figure 15a)
   2. Diode + Zener suppression: Used when in larger power and frequent On/Off (Figure 15b)

5. Manually exclusive output: For example, Y3 and Y4 control the forward running and reverse running of the motor, forming an interlock for the external circuit, together with the PLC internal program, to ensure safe protection in case of any unexpected errors.

A/D and D/A External Wiring

1. Master node
2. Slave node
3. Terminal resistor
4. Shielded cable

Note:

1. Terminal resistors are suggested to be connected to master and the last slave with resistor value of 120Ω.
2. To ensure communication quality, please apply double shielded twisted pair cable (20AWG) for wiring.
3. When voltage drop occurs between the internal ground references of two systems, connect the systems with Signal Ground point (SG) for achieving equal potential between systems so that a stable communication can be obtained.

Precision of the RTC (Second/Month)

Duration in which the RTC is latched: One week (Only version 2.00 and above are supported.)
