APPENDIX A - TERMINATION UNIT (NTDI01)
CONFIGURATION
INTRODUCTION
The IMDSI1 module can use a NTDI01 for termination. Dip-
shunts on the NTDI01 Termination Unit configure the digital
inputs. The digital input module accepts inputs of 24 VDC,
48 VDC, 125 VDC and 120 VAC, depending on the module
selected. Refer to Table
1-3 for the variations available.
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
A-1 to
determine the dipshunt strapping to configure your 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.
