Pin definition for the X105 interface.
1
Pin 5 (0 V
DC
) is used as the reference earth for pin 25 (24 V
DC
) and is connected
internally to the equipotential bonding via a 1 k
resistor to earth.
2
Maximum switching current: 1 A; maximum switching voltage: 24 V .
3.2.4.8. Interlock circuit with X101 and X105
Ring structure of the interlock safety circuit
The interlock circuit makes it possible to setup a safety infrastructure.
The basis for the function is an electrical ring structure that must be
closed for operation.
Safety elements
-2-
(e.g. EMERGENCY STOP buttons) can interrupt
the ring and as a result switch off the TopCon power supply.
For higher safety requirements, e.g. safety class 1, the option: ISR (In-
tegrated Safety Relay) is available.
For further information see chapter 4.2.4, page 101.
