Example: Low-Pass
Filter Configuration Any channel can be configured as a low-pass filter connected to the
normally open contact of the Form C relay. Figure 1-18 shows a typical
low-pass filter configuration. For this example, resistor R25 and capacitor
C25 are to be added. No configuration jumpers are required.
