Terminal base
specifications
Terminator I/O terminal bases are available
in screw clamp and spring clamp versions for
both half-size and full-size modules. Hot stamp
silkscreen labeling is used for numbering I/O
points, commons, and all power terminals.

Field Device Wiring and Power Options
Do not jumper modules together
to create a 24VDC bus when
using the “hot swap” feature.

Field device wiring options
Power your DC input devices from the
integrated 24VDC power supply bus.
T1K-08ND3 and T1K-16ND3 DC input
modules include jumpers for selecting the
internal 24VDC power supply available
for 2- and 3-wire field devices. Clearly
labeled triple stack terminals make it easy
to wire 2- and 3-wire devices ensuring
clean wiring with only one wire per
termination.
External user supplied 24VDC power, or
auxiliary 24VDC terminals from T1K-01AC,
can be easily applied directly to one end of
the terminal rows and jumpered across each
base in the system.
This is a convenient solution for powering
analog I/O and discrete DC output
devices whose modules do not have direct
access to the internal bussed 24VDC. If
current consumption increases, simply
add additional T1K-01AC power supplies
into the system.
Hot-swap feature
The hot-swap feature allows Terminator
I/O modules to be replaced while system
power is on. Be careful not to touch the
terminals with your hands or other conduc-
tive material to avoid the risk of personal
injury or equipment damage. Always
remove power if it is equally convenient to
do so.
Note
: Before hot-swapping analog or
DC output modules in a Terminator I/O
system, make sure that each of the analog
and DC output module’s 24VDC and 0
VDC base terminals are wired directly to
the external power supply individually. If
the external 24VDC and 0 VDC is jump-
ered from base to base in a daisy chain
fashion, and an analog or DC output
module is removed from its base, the risk
of disconnecting the external 24VDC and
0 VDC to the subsequent I/O modules
exists.
