About 1794-TB3T

The 1794-TB3T Flex I/O Temperature Module by Allen-Bradley is a terminal base unit module which provides a backplane connection to I/O modules and comes with 2 sets of cold-junction compensation Connections for use with any Allen-Bradley Flex I/O temperature modules. The 1794-TB3T uses the cage clamp termination method for I/O terminations and can make a maximum of 16 I/O connections. It has 6 common terminals, 4 voltage terminals, 8 chassis ground terminals, and 2 sets of CJC with 6 terminals for temperature modules. The 1794-TB3T is used in applications with 132V AC and 156V DC electrical ratings, and its maximum current capacity is 10 A. 
The 1794-TB3T Temperature Module has a terminal screw torque of 0.56 x 0.79 Nm (5-7 lb-in) and uses a copper wire with a 22-12 AWG size that can be stranded or solid and rated at 167 °F with a maximum insulation thickness of 3/64 inches. It has a working voltage of 12-24V AC/DC and has a Flexbus voltage of 5V at 640mA and a 2 A current across the I/O terminals. Its V/COM rating is 125V DC/AC at 50-60 Hertz. The 1794-TB3T offers a voltage isolation provided by the installed I/O module installed and the entire module comes with an open-style enclosure. It has a working temperature range of -20-70 °C (-4-158 °F) at 5-95% humidity without condensation, and it should be stored at a temperature between -40 and 85 °C (-40 and 185 °F). The 1794-TB3T module has dimensions of 94m x 94m x 69mm with the I/O module installed on it, and it is CE, UL, and CSA-certified.
