APPENDIX B - NIAI04 TERMINATION MODULE CONFIGURATION
INTRODUCTION
The IMFEC1  module can use the NIAI04 termination module
for termination in point-to-point applications. Select the input
type of each channel through dipswitches on the NIAI04 termi-
nation module. The FEC module can accept inputs of 4 to 20
milliamps, 1 to 5 VDC, 0 to 1 VDC, 0 to 5 VDC, 0 to 10 VDC
and -10 to +10 VDC.
CONFIGURING INPUTS
Figure B-1 shows the field input path through an NIAI04 ter-
mination module. Figure B-2 shows the terminal assignments.
Table B-1 shows dipswitch settings. Figure B-3 shows FEC
module to termination module cabling.
NOTE:
Input jumpers J6 through J20 on the IMFEC11 board must
be set to the voltage position. Refer to
IMFEC11 Input Jumpers (J6
through J20)
in Section 3.
