2-7. Disposal of Transistor Output Circuit
Âľ
z Output terminal
Basic unit’s transistor output has 1~4 public-end output.
z Exterior power
Please use DC5~30V steady-voltage power for load drive,
z Circuit insulation
Use photoelectricity coupling device to insulate PLC’s interior circuit and output
transistor. Besides, each public block is separate.
z Action denote
When drive optical coupling,LED lights,output transistor is ON.
z Response time
From photoelectricity coupling device drive (or cut) to transistor ON (or OFF), the time
PLC uses is below 0.2ms.
z Output current
The current is 0.5A per point。But as restrict by temperature goes up, the current is 0.8A
every four points.
z Open circuit’s current
Below 0.1mA
