TERMINATION UNIT CONFIGURATION
INTRODUCTION
The Digital Slave Module (DSM) uses a NTDO02 to terminate
field wiring from AC or DC loads. The termination unit provides
solid state relays for switching. The termination unit (TU) can
be daisy-chained to other TUs with solid state relays. Dip-
shunts allow the DSM to control any solid state relay with a
maximum of 9 per output. For example, 18 termination units
can be daisy-chained together by NKDO01 cables and be con-
trolled by one DSM. The NTDO02 is a direct replacement for
the NTDO01.
INSTALLATION
Table
shows the dipshunt configuration to interface the
NTDO02 to the DSM. The DSM has 16 outputs and requires 2
NTDO02s to interface all the outputs.
NOTES:
1.
1-8 represents strap numbers on the dipshunt where a blank
indicates an open strap and a line indicates a closed strap.
2.
XU3 - XU10 must be configured identically when connecting
two or more termination units in a daisy-chain.
After setting the switches on the DSM module and setting the
jumpers and dipshunts on the termination unit, install the
DSM, NTDO02 and cables as shown in Figure
shows the terminal assignments for NTDO02.
