Product Description

The robust option module ST2451 enables the incorporation of command
functions in the safety switch and key transfer system SAFEMASTER
STS. It has 3 selectable command devices and allows for starting and
stop of safety-relevant functions. Emergency stop buttons, illuminated but-
tons or selector switches, with or without key operation, are available as
command devices.
With just a few individual components from the SAFEMASTER STS sys-
tem, a great variety of different interlocking units can be created and com-
bined with various option modules. Numerous units with command func-
tions can be created. This enables a switch unit or locking switch to grow
into a true "control centre" from where command functions, status dis-
plays, release signals, main- and maintenance access gates can be con-
trolled. The special ribbon cable with plug-in connector ensures rapid and
problem-free internal connection of the individual components. Installation
a standalone command device is also possible through M20 or M25 cable
entries and double cage clamp terminals. The standard version made on
stainless steel guarantees the highest degree of stability and safety, even
in harsh environmental conditions. A comprehensive range of accessories
enables simple and time-saving installation directly at the access point.
The SL option module is a separate control and / or display unit without
the possibility of combination with other SAFEMASTER STS units. It is
intended for use in the hostile ambient conditions.
