tinb07e1-e 2011-07 Vacuum Gauge Controller 13
Connecting
1 Channel 1: Connect the sensor with to the CH1-A
or CH1-B connection. Use a shielded 1:1 cable.
2 Channel 2: Connect the sensor with to the CH2-A
or CH2-B connection. Use a shielded 1:1 cable.
3 Channel 3: Connect the sensor with to the CH3-A
or CH3-B connection. Use a shielded 1:1 cable.
3.3.5 RELAY
The switching functions and the error monitoring system
influence the state of several relays inside of the Vacuum
Gauge Controller. The RELAY connection (Fig. 3-4,
11, Pos. J) allows to utilize the relay contacts for
switching purposes. The relay contacts are potential-free
(floating).

n.c. not connected
COM common contact
NC break contact (normally closed)
NO make contact (normally open)
NOTE:
Pin 25 is used for supplying relays with a higher
breaking capacity. The supply contact is protected at
200 mA with a PTC element. The element is self-reset-
ting when switching the unit off or unplugging the
RELAY connector.
1 Connect the peripheral components with the
RELAY connection. Use a shielded connection
cable.
CAUTION
Improper sensor.
Sensors which are not designed for use with
the Vacuum Gauge Controller may damage
the unit.
Operate the Vacuum Gauge Controller with
proper sensors only. See Chapter 2.3.1 Sen-
sor connections, 8.
CAUTION
Multiple connection.
Only one sensor may be connected to each of
the channels. Otherwise the connected sen-
sors will be damaged.
Never connect more than one sensor per
channel.

25 +24 VDC, 200 mA. Meets
the requirements of a ground
protective extra low voltage
(SELV)
WARNING
Hazardous voltage.
Voltages above 60 VDC or 30 VAC pose a
shock hazard.
The RELAY connection may be used for
switching voltages of max. 60 VDC or 30 VAC
only. These voltages must meet the require-
ments of a ground protective extra low volt-
age (SELV).
