## **Approvals and marking** 

## **Applications** 

For switching lamp loads Input interface relay, e.g. for activation of PLC Output interface relay, e.g. for PLC-controlled loads 

## **Function** 

The contacts are actuated with an armature via a plunger. After the exciting voltage has dropped, a spring returns the armature (which is connected to the plunger) to its home position. The contacts can be actuated manually via a pushbutton on the front as well. This pushbutton acts at the same time as an operating position display. The contacts are closed when the pushbutton is pressed. The red pushbutton is flush with the front edge when there is no current. 

## **Indicators** 

Pushbutton: pressed in when the relay is supplied with current

## **Variants** 

**IK 8701. _ _ /001:** For switching low loads up to a maximum of 6 VA/W at 0,3 ... 60 V / 1 ... 300 mA The contacts also permit the maximum switching current. 

However, since the gold plating is burnt off at this current level, the unit is no longer suitable for switching low loads again afterwards. 

**IK 8701. _ _ /002:** Can be activated with 2-wire initiators, permissible residual current � 3 mA. Max. 6 glow lamps (0,5 mA each) are possible parallel to the mains button. **IK 8701. _ _ /003:** 3 mm contact opening (only NC and NO contact) **IK 8701. _ _ /005:** Same as IK 8701. _ _ /001 with a recovery diode to provide protection against voltage surges **IK 8701. _ _ /006:** For switching large inductive direct current voltage loads (DC 220 V, L/R = 30 ms), (only NC and NO contact) **IK 8701. _ _ /007:** For switching lamps with parallel compensation, 

For switching lamps with parallel compensation, e.g. HQ lamps. (only 1 or 2 NO contacts) Maximum parallel compensation 100 µF 

**IK 8701. _ _ /008:** With a recovery diode to provide protection against voltage surges 

**IK 8701. _ _ /009:** With a reliable release voltage of AC 120 V with a nominal voltage of AC 230 V. 

**IK 8701. _ _ /010:** Same as IK 8701. _ _ /006 with a recovery diode to provide protection against voltage surges **IK 8701._ _/016:** Nominal voltage DC 24 V Voltage range 0,8 ... 1,15 UN Temperature range - 20 ... + 55 � C (only 1 NC, NO or changeover contact) **IK 8701. _ _ /700:** Without manual actuation and an operating position display
