Binary Output Signals - Toshiba GRL100-701B Instruction Manual

3.2.2

Binary Output Signals

The number of binary output signals and their output terminals vary depending on the relay
model. 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].
All the models are equipped with normally open trip contacts for each phase.
The relay failure contact closes the contact when a relay defect or abnormality in the DC power
supply circuit is detected.

3.2.3 PLC (Programmable Logic Controller) Function
GRL100 is provided with a PLC function allowing user-configurable sequence logics on binary
signals. The sequence logics with timers, flip-flops, AND, OR, XOR, NOT logics, etc. can be
produced by using the PC software "PLC tool" and linked to signals corresponding to relay
elements or binary circuits.
Configurable binary inputs, binary outputs and LEDs, and the initiation trigger of disturbance
record are programmed by the PLC function. Temporary signals are provided for complicated
logics or for using a user-configured signal in many logic sequences.
PLC logic is assigned to protection signals by using the PLC tool. For PLC tool, refer to PLC
tool instruction manual.
