*Refer to the Life-test Curve. Life-test Curve (Reference Values) 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. Using as a Counter *1 | Inputs | Count | Reads counting signals.
