APPENDIX C - DIGITAL SLAVE INPUT MODULE
(IMDSI02)
INTRODUCTION
The IMDSI02 uses an NTDI01 for termination. Dipshunts on
the termination unit configure the digital inputs. The Digital
Slave Input (DSI) module accepts inputs of 24 VDC, 125 VDC
and 120 VAC.
Figure
shows an NTDI01 point configuration dipshunt
without
strapping, and the digital signal path from the field
device (contact) to the DSI module for a termination unit appli-
cation. Refer to Table
to determine the dipshunt strapping
to configure your application. Figure
shows the terminal
assignment and polarity for each of the digital input signals.
Refer to this figure when connecting field wiring to the NTDI01.
