The 1734-RTBCJC is a POINT I/O Removable Terminal Block (RTB) manufactured by Allen-Bradley. It features a removal handle and 5 input channels. The O/A and 1/A inputs of the terminal are used for high input while the 0/B and 1/B channels are for low input and the fifth channel is for the sensor cable shield. It weighs 0.061 kilograms and it is suitable for use with 1734 family of POINT I/O modules. It connects all field-side wiring for POINT I/O mounted adjacent to it or can be used for accomplishing cold junction compensation (CJC) required at the termination of a thermocouple wire. Note that the 1734-RTBCJC removable terminal block is only a component of a terminal base assembly, which also consists of a POINT I/O module with a locking mechanism, a mounting base, controllers, and adapters from other assemblies. Depending on the mounting base orientation, it can be mounted vertically or horizontally and it provides vertical access to wire and screw terminations.

The 1734-RTBCJC removable terminal block separates independently of the I/O mounting base and if wired properly, there is no need to rewire terminations. It can be assembled alongside the POINT I/O mounting base without tools and its installation, removal or replacement does not require the removal of any wiring. The Cold Junction Compensation (CJC) input points to the maximum temperature for the selected input type when the CJC is open and this sets the alarm which remains active for as long as the input signal is faulted above the maximum. Before installing, removing or replacing the 1734-RTBCJC removable terminal block, ensure that all power is cut off from it because connecting or disconnecting it with field-side power applied causes an electrical arc which could result in an explosion in hazardous locations.
