APPENDIX B - TERMINATION MODULE (NIAI04)
CONFIGURATION
INTRODUCTION
The Analog Slave Input Module (IMASI02) uses a NIAI04 for
termination. Dipswitches on the NIAI04 module configure the
fifteen analog inputs for the ASI slave. The ASI accepts inputs
of 4-20 milliamps, 1-5 VDC, 0-1 VDC, 0-5 VDC, 0-10 VDC and
-10 VDC to +10 VDC.
CONFIGURING INPUTS
Figure
shows the NIAI04 and the analog signal path from
the field device to the ASI module for a termination module
application. The values in the figure are actual values from the
devices on the module. See Figure
for the dipswitch set-
tings. Be sure to recheck the dipswitches before you install the
NIAI04. The switches may be changed during handling.
Figure
shows the terminal assignments and Figure
shows the cabling for the ASI. Figure
summarizes the pos-
sible applications and dipswitch settings.
NOTE: The dipswitch analog input (AI) number AI1-AI15 corre-
sponds numerically to the analog input number.
