Example: Differential
Divider or Filter
Configuration
Any channel can be configured as a differential divider (with op tional filter)
connected to the normally open contact of the Form C relay. The d ifferential
divider requires that two channels be used.
Figure 1-23 shows channel 24 and 25 in this configuration wi th the optional
filter. For resistors R24 and R25, add a cross-channel capacito r for a
differential filter or add a cross-channel resistor for a differential d ivider.
No configuration jumpers are required.
