5. Response time
The time from when the PLC drives (or shuts down) the photocoupler until the transistor is turned on (or off) is
shown in the following table.
*1. The transistor OFF time is longer under lighter loads. For example, under a load of 24V DC 40mA, the
response time is approx. 0.3ms. When response performance is required under light loads, provide a
dummy resistor as shown below to increase the load current.
6. Output current
The maximum resistance loads for the main unit or input/output powered extension units and output
extension blocks are shown in the following table.
The ON voltage of the output transistor is approx. 1.5V.
When driving a semiconductor element, carefully check the input voltage characteristics of the applied
element.
