Connecting Analog Inputs to the
PPC-2021 — 2025
The Analog Input Terminal Board (AITB) connects to the
analog input module through the SCSI connector (bottom
center of the analog input module). The AITB accommodates
wiring thermocouples, RTDs, and voltage/current linear
inputs.

to AITB
Connecting the AITB to the PPC-202x
Refer to Figure 2.28. Connect the 50-pin SCSI connector from
the analog input module(s) to the analog input terminal block
(AITB). Table 2.13 on page 48 shows the AITB pinout.
NOTE!
If more than one AITB has been installed, it may be
useful to label both ends of the SCSI cable and the
AITB with the address selected on the corresponding
analog input or high isolation analog input module.
