Connecting Wiring using a 1794ĆTB3 and ĆTB3S Terminal Base
Units
1. Connect individual input wiring (N+, N–,) or (D+, D–) to
numbered terminals on the 0–15 row (A) as indicated in the table
below.
!
ATTENTION: Do not connect maximum input
voltage simultaneously to all inputs if the module
ambient temperature is expected to exceed 40
o
C.
!
ATTENTION: If the module ambient temperature is
expected to continuously exceed 40
o
C, you must limit
the input voltage using an external resistor on each
input. A 1K resistor effectively limits a 24V sensor
signal to about 15V at the input. Do not limit the input
to less than 6V.
2. Connect the associated input common to the corresponding
terminal on the 16-33 row (B) for each input as indicated in the
table below.
