Safe Brake Relay

With the Safe Brake Relay, the brake is controlled in accordance with IEC 61508 SIL 2 and EN ISO 13849‑1 PL d and Category 3.

Дизайн



The Safe Brake Relay can be installed below the Power Module on the shield connection plate.

The Safe Brake Relay has the following connections and interfaces:

  • 1 two-channel transistor output stage to control the motor brake solenoid
  • 1 connection for the cable harness (CTRL) to the Power Module in blocksize format
  • 1 connection for the 24‑V‑DC power supply

The connection between the 24 V DC supply and the Safe Brake Relay must be kept as short as possible.

The scope of supply of a Safe Brake Relay includes the following:

  • 2 cable harnesses for connecting to the CTRL socket of the Power Module
    • Length 0.32 m (1.05 ft) for frame sizes FSA to FSC
    • Length 0.55 m (1.80 ft) for frame sizes FSD to FSF
