Jumper Settings
A.3.2 A Module Process Input Type – Pulse
To configure an A module Pulse Inputs, set the jumpers according to these instructions.
Configure Inputs 1 and 2 for one of three analog signal types:
• For 1-5 VDC Input, remove both RTD and 4-20 jumpers.
• For 4-20 mA Input, install the 4-20 jumper.
• For RTD Input, install the RTD jumper.
Configure Input 3 for one of the three signal types:
• Analog Input:
− Install all four “A” jumpers.
− For 1-5 VDC Input, remove the 4-20 jumper.
− For 4-20 mA Input, install the 4-20 jumper.
• Pulse Input:
− Remove all four “A” jumpers and install the two “P” jumpers.
− Install the DC coupling jumper.
Configure Input 4 for pulse signal types:
• Remove all four “A” jumpers and install the two “P” jumpers.
• Install the DC coupling jumper.
• Install the HI signal threshold.
• Remove the 4-20 jumper.
Refer to Figure A-3 for default input and output jumper settings: Inputs Ch1 = 4-20mA,
Ch2 = 4-20mA, Ch3 = Pulse, Ch4 = DC coupled Pulse and Output Ch2 = 4-20mA.
