I/O module SPTR 6B11 has a fixed 40 ms delay
for the control of output relays B and C. This
delay is added to the normal operation delay.
When output B is used as a second trip output
the fixed 40 ms delay is by-passed by means of
switch SGR/7.

module are permanently wired to the card loca-
tions of the feeder terminal. Since the output
signals are individually wired from each card
location to the I/O module, the modules have
to be plugged into the relay case as shown in the
Fig. on the front page to secure that the connec-
tion diagram for the relay assembly corresponds
to the physical function of the relay.
