Output relay
module
The output relay module SPTR 6B3 is located
behind the system front panel of the relay to-
gether with the power supply module. The out-
put relay module forms its own withdrawable
relay module after removal of the system front plate. The module contains all output relays,
A...F, the control circuits of the relays as well as
the electronic circuitry of the external control
inputs.

The input and output signals of the output re-
lay module are related to the fixed positions of
the relay modules which cannot be changed in
the relay housing. The output signals from each
relay module and PC-board location are wired
individually to the output relay module. It must be pointed out that the relay modules have to
be plugged into the relay case as illustrated in
the figure on the front page in order to secure
that the connection diagram drawn for the re-
lay assembly also would correspond to the physi-
cal function of the protective device.
