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.
	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

Panel Cutouts

Panel cutouts are as shown below. (according to DIN43700).

Note:
1. The mounting panel thickness should be 1 to 5 mm.
2. To allow easier operation, it is recommended that Adapters be mounted so that the gap between sides with hooks is at least 15 mm (i.e., with the panel cutouts separated by at least 60 mm).
3. It is possible to horizontally mount Timers side by side. Attach the Flush Mounting Adapters so that the surfaces without hooks are on the sides of the Timers. If they are mounted side-by-side, water-resistance will be lost.

Dimensions with Front Connecting Socket

* These dimensions depend on the kind of DIN Track. (Reference value)
