Signal Output Contacts

13.3.1

Programmable Signal Contacts

Signal contact outputs enable the relay to send signals
to other devices by closing (or opening) the
connection between a pair of terminals. Each signal
contact output is controlled by up to twenty functions
selected from Table 6.x. The 7UT512 relay has four
contact outputs and the 7UT513 relay has ten contact
outputs. If desired, a function can activate more than
one signal contact relay.
6201 SIGNAL CONTACT 1
6202 SIGNAL CONTACT 2
6203 SIGNAL CONTACT 3
6204 SIGNAL CONTACT 4
6205 SIGNAL CONTACT 5
Each signal relay can be independently activated by up to twenty (20) functions (chosen from the
list in section Table 13.1). The default configuration is listed below:

External Trip 1 signal (received through another signal input) will be blocked, will be
blocked from causing a trip ( ), or will be issued by a signal to this discrete input ( ).

Alarm functions have effect only when the
corresponding protection function is enabled and
active. Functions with a ">" sign prefix can be
assigned to both signal contact inputs and signal
contact outputs to pass a signal through the relay
independent of the relay's protective functions (of
course, the relay must be operational).
