The IMDSI13, IMDSI14, and IMDSI22 modules use an NTDI01
termination unit. Dipshunts on the termination unit configure
the digital inputs. The digital input module accepts inputs of
120 VAC, 24 VDC, 48 VDC, and 125 VDC, depending on the
module selected.
Figure A-1 shows the NTDI01 dipshunt without strapping, and
the digital signal path from the field device (contact) to the DSI
module for a termination unit application. Refer to Table
to determine the dipshunt strapping to configure the applica-
tion. Figure A-2 shows the terminal assignments for the digital
input signals. Refer to this figure when connecting field wiring
to the NTDI01 termination unit.
