3.2 Binary Input and Output Signals
3.2.1 Binary input signals
The binary input circuit is provided with a logic level inversion function as shown in Figure
3.2.1. Each input circuit has a binary switch BISW which can be used to select either normal or
inverted operation. This allows the inputs to be driven either by normally open or normally
closed contact. If a signal is not input, the function concerned is disabled. The setting of binary
input can be performed by RSM100.
Further, all binary input functions are programmable by PLC (Programmable Logic Controller)
function.

3.2.2 Binary output signals
The signals shown in the signal list in Appendix C 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. A 0.2s delayed drop-off timer can be
attached to these assigned signals. The delayed drop-off time is disabled by the [BOTD]. The
output circuit can be configured by RSM100. Appendix D shows the factory default settings.
The relay failure contact closes the contact when a relay defect or abnormality in the DC power
supply circuit is detected.
