Life-test Curve (Reference Values)

Resistive load

Inductive load

A current of 0.15 A max. can be switched at 125 VDC (cosφ=1) and current of 0.1 A max. can be switched if L/R=7 ms. In both cases, a life of 100,000 operations can be expected.

I/O Functions

Using as a Counter *1

Inputs	Count	• Reads counting signals. • Increment and decrement inputs accepted.
Inputs	Reset	• Resets present value and outputs.*2 • Counting cannot be performed during reset input. • Reset indicator is lit while reset input is ON.
Outputs	OUT	Outputs signals according to the specified output mode when a set value is reached.

*1. For information on operation of I/O functions, refer to Catalog.
*2. In elapsed time mode, the present value returns to 0; in remaining time mode, the present value returns to the set
value.

The following table shows the delay from when the reset signal is input until the output is turned OFF. (Reference values)

Minimum reset signal width	Output delay time
1 ms	0.8 to 1.2 ms
20 ms	15 to 25 ms
