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.
Classification
Y000 to Y002
Main unit
Y003 or more
Input/output powered extension unit
Output extension block
*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 resistance as shown to the right to
increase the load current.

Fuse Load
6. Output current
The maximum resistance loads for the 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.
