The KSS is a heavy-duty solenoid
controlled key driven electrical switch
interlock ideal for the controlled isolation or
switching of low current. This product is used
where a process can send a signal to release
a key, e.g. a robot has to finish a cycle prior to
isolation. Upon removal of the key, the KSS
switch contacts change to isolate the process.
This type of isolator should be used for short
term, off load isolation. The unit is ready for
mounting into an existing panel or for surface
mounting within its own IP65 rated enclosure.
The KSS is manufactured from either brass or
stainless steel.
OPERATION
The Castell KSS Solenoid Controlled Switch is typically used for machine isolation in applications where a machine has to
finish a cycle prior to isolation.
KSS Solenoid Controlled Switch
1
Key is trapped while power is on,
solenoid is de-energised.
2
An external signal is received and
LED is illuminated. Push the button
to energise the solenoid and
remove the key.
3
Solenoid is energised, switch is
locked out and key is free.
While the power is on and a machine
is running, the key is trapped in the
Solenoid Controlled Switch.
To release the key, an external signal
must be received to energise the
solenoid. With the solenoid energised,
the LED will illuminate to confirm
that the key can be removed ensuring
the power is off.
The key can now be removed and
taken to open the door lock and
gain access to the machine area.
The KSS is available with different solenoid voltages as AC: 24, 110 or 240 V or DC: 12, 24, 110, 240 V (see order
information on page 7 for more details).
The KSS comes with 4 or 6 contacts as standard with contacts arrangements as 2NO/2NC, 4NC or 3NO/3NC or 6NC.
The KSS is available as a back of panel mount (BOB) and as a surface mount version with an enclosure (FOB).
