Versions

• 1BA1: ASIsafe channel 1 on 1 NC contact from the actuator and channel 2 on 1 NC contact from the solenoid
• 1BA3: ASIsafe channel 1 on the first NC contact from the actuator and channel 2 on the second NC contact from the actuator
• 1BA4: ASIsafe channel 1 on 2 NC contacts (two-channel) from the actuator, and channel 2 on 1 NC contact from the solenoid. The position switch transfers the information of actuators to a transfer channel because the discrepancy of the two actuator contacts is already evaluated in the switch.

The 3SF1324-1S.21-1BA4 safety switches are also recommended where there are several protective door tumblers and reliable diagnostics and quick restart capability of equipment is required.

• A response is received from the magnet.
• No opening of the doors after the solenoid is unlocked.

In connection with an ASIsafe MSS modular safety system or a DP/AS-i F-Link, it is possible to achieve SIL 2 according to IECВ 61508 or PLВ d according to ISOВ 13849-1. They comply with the standard EN ISO 14119. A TГњV certificate is available.
