Analog Input Card with Thermocouple Input Installation Instructions

Voltage/Current Selection and Wiring

Set the mode select jumpers (Select 1

SEL1

and Select 2

SEL2

on option board), (see Figure 6) for input. Set

jumpers to I if using 4-20mA or V if using 0-10 V.

When using the +/- 10 volt or the 0-20 mA ranges, the option card selection jumpers should be set to the
appropriate setting. The following table lists the voltage and current selections

NOTE: Only one input is available per connector, two channels per option card, with the exception of the low level input channel, J3.

Enclosure Reassembly

Once cabling is complete, position the backplate over the enclosure and reinstall the backplate screws. Use the
torque pattern shown in Figure 7 to prevent distorting the backplate gasket. Torque screws to 15 in-lb (1.7 N-m).

1. Ensure no excess cable is left inside the enclosure and tighten cord grips.

2. Reconnect power to the indicator.

Figure 7 Enclosure Backplate
