Brake application via the safe digital input SBC

The response time for applying the brake via the safe digital input SBC is made up of the sum of the following times:

  • Response time of brake module
  • Switching time of brake

Brake module response time

Switching time of brake

Time from disconnection of the DC 24 V voltage at the safe digital input SBC until disconnection of the brake voltage.

≤ 10 ms

  • SEW‑EURODRIVE brakes with two-coil system (3-wire technology):
    • Brake module as safety device according to category 1, PL c
    • Use the brake application time t2,II for cut-off in the DC and AC circuit.
    • Brake module as safety device according to category 3, PL d
    • Use the brake application time t2,I for cut-off in the AC circuit.
  • The times are provided in the documentation for the brake.
  • Brakes with single-coil system (2-wire technology):
  • Use the brake application time specified in the documentation for the brake.
