Ratings
Rated supply voltage 12 or 24 VDC, permissible ripple: 5% max.
Switched by shorting and opening terminals.
Operating voltage range 12 V: 90% to 110% of rated voltage
24 V: 80% to 110% of rated voltage
Power consumption 12 V: Approx. 60 mW
24 V: Approx. 120 mW
Control output Solid-state output: 100 mA
Voltage drop: 1.2 V max. (see note 2)
Note: 1. Residual voltage on reset input when shorted: 1.0 V.
2. Contact output switching capacity: 100 mA, but rated coil current of relay loads must be 75 mA or less.
