4.3. Output relays
The VAMP 135 relay is equipped with five configurable output
relays and a separate output relay for the self-supervision
system, Figure 4-1.
•
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.
