Allen Bradley's 1794-TB32 Flex I/O 24 V AC/DC terminal base unit is a terminal base unit designed for 32-point modules and provides a connection point for input/output wiring. It has a maximum connection capacity of 32 I/ OS, with 8 common terminals and 8 voltage terminals for 31.2 V DC applications. It has A current capacity of 10 A, a FLEXBUS rating of 640 mA and 5 V DC, a maximum I/O terminal rating of 2 A, a V/COM terminal rating of 31.2 V DC/AC, and a frequency of 50 to 60 Hz. It is capable of providing 50 volt circuit isolation and basic type insulation tested at 2121 volts DC for 1 minute between the field terminal and the FLEXBUS.
The 1794-TB32 has IEC T4 and T4A (North America) temperature codes and comes with an open housing. It operates in a temperature range between -20 and 70 degrees Celsius (-4 and 58 degrees Fahrenheit), has a non-condensing humidity level of 5% to 95%, and is stored at -40 to 85 degrees Celsius (-40 to 185 degrees Fahrenheit). The 1794-TB32 has been tested to maintain standard specification performance at 5 G operating vibration and 30 G impact ratings. It measures approximately 94 x 94 x 69 mm (3.7 x 3.7 x 2.7 inches), has modules installed, and is c-UL-us and CSA certified.
