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.
Features
- According to IEC/EN 61812-1
- Galvanic separation between control contact and supply voltage
- Wide auxiliary range
- Adjustable operate delay
- 2 changeover contacs delayed
- LED-indicator for power and contact position
- Width: 45 mm
