Contact protection relay
BA 7961
Article number:

Type:
BA7961.82 AC/DC80-230V t1=0,1-10S
Description
The contact protection relay BA 7961 protects sensitive control contacts of e.g. digital plc outputs, limit contacts on measuring devices, low load reed contacts against early wearing. It has a low input consumtion on B1-B2 control input and a high switching capacity of the output using a robust relay for mains voltage with 2 changeover contacts. Unintended switching caused by contact bouncing or vibrations are suppressed by an adjustable on delay and a fixed off delay. The auxiliary supply A1/A2, the control input B1/B2 and the output contacts are galvanically separated. The control input must be voltfree, no external voltage must be connected. 2 LEDs show connected power supply and status of the output relay.
