APPENDIX A - NTDI01 TERMINATION UNIT CONFIGURATION
INTRODUCTION
The IMDSO01, IMDSO02 and IMDSO03 Digital Output Mod-
ules (DSO) can use the NTDI01 Digital I/O Termination Unit
(TDI) for termination. Figure
shows the location of dip-
shunt sockets, fuses, connectors and terminals on the TDI cir-
cuit board. Dipshunts on the TDI unit are used to switch
between three possible ways of powering each digital output.
Dipshunt sockets XU1, XU3, XU5, XU7, XU9, XU11, XU13,
and XU15 correspond to digital outputs one through eight. All
other dipshunt sockets should not have a dipshunt installed.
Table
shows the possible dipshunt configurations. Figure
shows the termination assignment and polarity for each of
the digital output signals. Refer to this figure when connecting
field wiring to the TDI unit. Figure
shows the cable connec-
tions required when using the TDI unit with a DSO module.
This information is provided as a quick reference guide for per-
sonnel installing the TDI unit. Refer to the NTDI01 instruction
for complete information.
