3.2.2 Binary Output Signals
The number of binary output signals and their output terminals vary depending on the relay
models. For all models, all outputs except the tripping command and relay failure signal can be
configured.
The signals shown in the signal list in Appendix B can be assigned to the output relay individually
or in arbitrary combinations. Signals can be combined using either an AND circuit or OR circuit
with 6 gates each as shown in Figure 3.2.2.1. The output circuit can be configured according to the
setting menu. Appendix D shows the factory default settings.
A 0.2s delayed drop-off timer can be attached to these assigned signals. The delayed drop-off time
is disabled by the scheme switch [BOTD].
The GRZ100 can implement transmission of signals to the remote terminal either by opening or
closing the output contact in response to a request from the telecommunication equipment. The
transmission signal is assigned to BO13 of IO2 by the binary output setting.
The relay failure contact closes the contact when a relay defect or abnormality in the DC power
supply circuit is detected.
