POINT I/O Cold Junction Compensation
Wiring Base Assembly
(Cat. No. 1734-TBCJC)
The wiring base consists of a base (1) and a removable terminal block
(1734-RTBCJC)(4). The 1734-TBCJC uses screw-clamp termination.
Installing the Wiring Base
1. Position the wiring base vertically above the installed units (adapter,
power supply or existing module).
2. Slide the wiring base down allowing the interlocking side pieces to
engage the adjacent module or adapter.
3. Press firmly to seat the wiring base on the DIN rail. The wiring base will
snap into place.
4. To remove the wiring base from the DIN rail, remove the module, and
use a small bladed screwdriver to rotate the base locking screw to a
vertical position. This releases the locking mechanism. Then lift straight
up to remove.
Installing the Removable Terminal Block
A removable terminal block is supplied with your terminal base. To remove,
pull up on the RTB removal handle.
