6 output specification and wiring methods
6-3.Transistor Output Type
Transistor output models support high speed pulse output and normal transistor these two types;
l Output Terminals
There are 1~4 COM outputs on transistor output type CPU units
l External Power Supply
Please use DC5~30V this stable power supply to drive the load drive.
l Circuit Isolation
Inside PLC, we use optical couples to isolate the internal circuit with the output
transistors; besides, public blocks isolate to each other.
l Action Indication
W
hen driving optical couples, LED will be ON, the output transistors will be ON;
l Response Time
From optical couple being ON (or OFF) to transistor being ON (or OFF), PLC
needs time below 0.2ms.
l Output current
Each output’s current is 0.5A. But limited by the temperature rising, every 4
points’ total current should be below 0.8A.
l Open circuit current
Below 0.1mA
Normal Transistor
Output
