Example: Normally Open
Terminal Pullup
Configuration
Any channel can be configured as a pullup (or pulldown) resistor connected
to any of the contacts of the Form C relay. Figure 1-21 shows channel 25
with the pullup attached to the NO contact. For this example, SIP resistor
pack RP24-31 is to be added. Set two configuration jumpers as shown in
Figure 1-21 (PU NO).
