Description

Description
I/O Terminal Blocks are generic wiring bases that provide
module mounting, backplane communications, and terminals
for user connections. Two modules can be installed on one
terminal block. Modules screw onto the terminal block for
vibration resistance. Modules can be removed without
disturbing field wiring.
For each I/O module, there are three isolated groups of
common terminals: the A group (internally connected together)
and B group (internally connected together) are typically used
for power connections. The E group has five common terminals
that are internally tied together and isolated from the power
and point terminals. They can be used as needed for
application wiring. Terminals 1 – 16 are used for I/O wiring.
Each terminal accommodates up to one AWG #14 (2.1 mm2) or
two AWG #18 (0.86mm2) through AWG #22 (.35 mm2) wires.
Use copper wire rated for 90 degrees C. Recommended
terminal torque is 4.5 in/lbs. The maximum current through
any one terminal is 10 Amps.
I/O Terminal Block IC670CHS102 permits hot insertion/
removal of modules without affecting the Bus Interface Unit or
other modules in the I/O Station. Hot insertion/removal can
only be performed in non-hazardous locations.
Compatibility
I/O Terminal Block IC670CHS102 has a projecting alignment
slot at each module position. It must be used with modules
whose catalog number suffix is J or above. These modules have
a projecting tab that fits into the alignment slot.
Bus Interface Unit version 2.1 or later is required for hot
insertion/removal of modules in the I/O Station.
Mixing IC670CHS10x terminal blocks with IC670CHS00x
terminal blocks in the same I/O station is not recommended.
Caution
I/O Terminal Blocks IC670CHS102 and IC670CHS002B or later
have a metal grounding strip underneath. They must be used
with a grounded conductive DIN rail. Do not use these
terminal blocks with A version I/O Terminal Blocks or BIU
Terminal Block IC670GBI001, which do not have a metal
grounding strip; the system would have poor noise immunity.
Installing a Terminal Block on a DIN Rail
A new I/O Terminal Block is protected by a pair of sturdy labels.
Keep these labels in place while installing the terminal block to
prevent environmental contamination of block components.
Follow the steps below to install the terminal block on a DIN rail.
1. Tilt the I/O Terminal Block and position it over the rail,
catching the rail behind the tabs in the terminal block.
2. Pivot the terminal block downward until the
spring-loaded latches click into place.

Removing the I/O Terminal Block from a DIN Rail
If Auxiliary Terminal Blocks are present, they must be taken off
before the I/O Terminal Block can be removed from the DIN
rail. Then follow the steps below to remove the I/O Terminal
Block.
1. Loosen the DIN rail clamp screw.
2. Insert a small flat-blade screwdriver into the upper latch
and pry it outward.
3. Pull up gently on the top of the terminal block to
disengage the upper latch from the rail. Insert the
screwdriver into the lower latch and pry it outward to free
the terminal block.
