Pulse input/frequency input jumpers
The Pulse/Frequency Input Module with Digital Outputs (Module ID D) contain jumpers to set the de-
energized Input Filter Cutoff Frequency. All four inputs are factory set to 500 KHz as shown in Figure 23.
To change, use needle nose pliers and move the jumper(s) to the desired position. See the figure below for
the default positions and jumper settings for 100 KHz and 5 KHz.
Pulse/frequency card wiring
The pulse frequency card input is designed to accept a contact closure type transmitter. The typical wiring
circuit is shown below.
