Auxiliary voltage
The external auxiliary voltage Uaux (standard 40 to 265 V
ac/dc or 24 V dc, option B) for the relay is connected to the
terminals X1: 11 - 12
Note:
Polarity of the auxiliary voltage U
aux
(24 V dc, option B):
+ = X1:11 and - = X1:12.

Output relays
The VAMP 150 relay is equipped with five configurable output
relays and a separate output relay for the self-supervision
system
•
Trip relays T1 and T2 (terminals X2: 19 - 20 and 16 - 17)
•
Alarm relays A1 - A3 (terminals X2: 13 - 14, 11 - 12 and 9 -
10)
•
Self-supervision system output relay IF (terminals X2: 7 - 8)
•
The trip relay T2 can also be used for alarm purposes.
4.4.
Serial communication connections
•
RS 232 serial communication connection for computers,
connector LOCAL (RS 232), connector on the front panel of
the relay
•
Remote control connection, connector REMOTE (TTL) on
the rear panel of the relay (terminal X5). See also Table
2.5.2-1.
4.5.
Current transducer
The output signal, i.e. 0 - 20 mA or 4 - 20 mA, of the integrated
mA transducer is available on terminal X2: 1 - 2.
