Description
SRTC is an extension module, which can be used with any basic
device from the IMO range of safety relays to realise delayed
power off to the critical parts of a machine. This may be
necessary for example, when a machine tool must be moved to
the start position.
The SRTC is connected to the basic device using one of its safety
contacts. If a failure occurs, switching of the basic device will not
be possible. The time-delay is adjusted by a potentiometer.
