DC power supply

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 0.1 A to ensure normal operation of the model.
1. Diode suppression: Used when in smaller power [Figure 17a] [Figure 18a]
2. Diode + Zener suppression: Used when in larger power and frequent On/Off [Figure 17b]
[Figure 18b]

Manually exclusive output: For example, Y2 and Y3 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.
 RS-485 Wiring
DVP12SA2 provides one set for each COM2 and COM3
provides one set of COM2.

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.
