Provides a red visual state indication in SIRIUS ACT illuminated pushbutton and indicator assemblies.
Supports warning, stop, fault or process-status indication in industrial operator stations.
Suitable for like-for-like replacement when voltage, color, terminal type and holder arrangement match.
It is a SIRIUS ACT LED module with an integrated red LED for 24 V AC/DC signaling circuits.
The exact model uses spring-loaded terminals for conductor connection.
Siemens specifies 24 V AC at 50 or 60 Hz and 24 V DC operation.
It is designed for front plate mounting on the rear side of a compatible SIRIUS ACT holder.
Not automatically. The required color, voltage, terminal method and signaling function must match the machine documentation.
Confirm the complete suffix, 24 V AC/DC rating, red LED, spring-loaded terminals, holder compatibility and required order quantity.
