Configuring Inputs
Figure A-6 shows the cabling for the IMASI023 module. The
NKAS01 (or NKAS11) cable connects the termination unit to
the IMASI03. The NKAS01 cable has PVC insulation and is
rated for 80° C (0 to 176° F) at 300 V (UL rated type CL2). The
NKAS11 cable has non-PVC insulation and is rated for 90° C (0
to 194° F) at 300 V (UL rated type PLTC).
NOTE: The example in Figure A-4 is an NTAI06 termination unit with revision B
hardware.

Input Type Input Description
Single ended
voltage
This jumper configuration connects the minus (-) input terminal to I/O COM on
the NTAI06. The IMASI23 measures the voltage at the plus (+) input terminal
with respect to the C terminal. No connection to the C terminal is necessary.
Differential voltage This jumper configuration connects the plus (+) and minus (-) inputs directly to
IMASI23 differential input. Channel to channel and channel to system signal
isolation is achieved for all voltage input types, including high level voltage,
millivolts and thermocouples. No connection to the C terminal is necessary.
System powered
4-20 mA
This jumper configuration connects the plus (+) input terminal to system +24
VDC through a fuse on the NTAI06. The minus (-) input terminal connects to a
precision resistor that generates a single ended voltage (1 to 5 V) for the
IMASI23 to measure. No connection to the C terminal is necessary. INFI 90
OPEN must have +24 Volts (system power) installed.
