Extension Module F122

Extension of safety contacts

Characteristics

Relay conforms to standards EN 60204-1 and VDE 0113-1 6 safety contacts 2 auxiliary contacts Safety category according to the main unit

Description

For safety power circuits - to be used for personal- and object protection -we supply emergency-stop relays, safety guard monitors and two-hand relays. The relays fulfil the requirements: EN 954-1 (3.97); EN 574; EN 60204-1 and VDE 0113-1.

If the number of contacts in safety-oriented controls is not sufficient, then contact module F122 can be used for increasing the number of contacts.

Contact module F122 is activated via one or two safety contacts of the main unit.

Mode of Operation

Models and Ordering Data

Comment

If both internal relays are activated, the safety output contacts are closed. The two LEDs in the front indicate the status of the relays. The N/C contact 81-82 has to be connected to the feedback loop of the control unit to monitor the safe function or the F122.

All F series safety relays can be connected to the contact module F122. The use of single or dual channel activation depends on the level of safety required for the control unit. Please pay attention to the wiring examples as detailed below.
