Overview
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 recom-
mended where there are several protective door tumblers and
reliable diagnostics and quick restart capability of equipment is
required.
•
A response is received from the solenoid
• No
opening of the doors required after the solenoid is
unlocked
In connection with an ASIsafe MSS modular safety system or an
ET 200SP F-CM AS-i Safety ST module, it is possible to achieve
SIL
2 according to IEC
61508 or PL d according to ISO
13849-1.
They comply with the standard EN ISO 14119. A TÜV certificate
is available.
