Terminal Block Quick Connect Components for 16-Point Modules
Installing a 16 point module typically takes 2 1/2 hours to wire from a PLC to a terminal blocks or
strip. With the TBQC, you simply snap the terminal block onto a DIN rail, remove the I/O
module’s terminal assembly, snap in the I/O faceplate, and connect the cable. This reduces wiring
time to about two minutes, thereby reducing wiring costs and errors. A complete assembly consists
of a terminal block, an I/O Face Plate, and a cable.
Terminal Blocks
Terminal blocks have three rows of terminals, arranged in three levels, as shown in Figure H-1.
These terminal blocks feature an easy to use captive-screw, “rising cage” type connection system.
Catalog numbers for the terminal blocks and the modules they can be used with are listed below.

* This Terminal Block may be used with most I/O modules that have up to 16 I/O points (can
not be used with 32 point modules). Jumpers may have to be added; for details of required
wiring connections, refer to module specifications in GFK-0898.
Cable Current Rating
Each conductor in these 24-conductor cables has a current rating of 1.2 Amps. If using these cables
with a 16-point Output module with a higher output current rating, you must use the lower value of
1.2 Amps for the maximum load current rating . If you have field devices that require more than
1.2 Amps, do not use a TBQC assembly - use the standard Terminal Board that comes with the
module instead.
