APPENDIX A - NTDI01
TERMINATION UNIT CONFIGURATION
INTRODUCTION
The IMDSM04 uses an NTDI01 for termination. Dipshunts on
the termination unit (NTDI01) configure the digital inputs. The
Pulse Input Slave Module (DSM) accepts inputs of 4 to 6 VDC,
21.6 to 27 VDC and 50 millivolts to 10 Volts peak to peak.
Figure A-1 shows the dipshunts and terminal blocks on the
termination unit.
CONFIGURING INPUTS
Figure A-2 shows the input circuit with the dipshunts, termi-
nal blocks and I/O circuits on the DSM. Figure A-2 also shows
the dipshunt connection to the NKTU01 cable that plugs from
the termination unit to B1 on the DSM.
Figure A-3 shows dipshunt configuration for the possible
NTDI01 applications.
XU7 connects the 24 VDC I/O power to the preamplifiers on
the DSM. If no preamplifiers are used do not install XU7. Fig-
ure
A-4 shows the terminal assignments for the termination
unit.
