Connecting Wiring using a 1794ĆTB3 and ĆTB3S Terminal Base
Units
1. Connect individual input wiring (A+, A–, B+, B–, Z+, Z–, G+,
G–) 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 (3-wire devices only) to
the corresponding terminal on the 16-33 row (B) for each input as
indicated in the table below. (Commons are internally connected
together.)
