About 1794-TB3TS

The 1794-TB3TS Flex I/O Terminal Base Unit by Allen-Bradley is a device which provides terminal connection points for most Flex I/O module wiring and its connection with other terminal base units form the basis for the backplane. The module has an I/O connection capacity of 16 I/O and it has 10 common terminals, 4 voltage terminals, 8 chassis ground terminals, and 2 sets of cold-junction compensation (CJS) used specifically for Flex I/O temperature modules. It has an application electrical rating of 125V AC/DC and has a maximum current capacity of 10A. The 1794-TB3TS uses a DIN Rail or Wall/Panel mounting method and it provides connected Flex I/O module termination via the spring clamp. It has a FLEXBUS rating of 640mA at 5V DC and provides a 2A max current at the I/O terminals. 
This terminal base has a V/COM rating of 125V DC/AC with 10A current at 50-60 Hz and provides voltage isolation depending on the module connected but can provide 125V isolation between field wiring terminals to FLEXBUS. The 1794-TB3TS uses the 1.2 mm (3/64 in) thick insulated copper wire with 22-12 AWG rated wire size at 75 °C (167 °F) and the whole module has an open-style enclosure. It is designated the T4A and T4 temperature codes (maximum temperature of 135 0C) it has an operational temperature range of -20-70 °C (-4-158 °F) at a relative humidity range of 5-95% without condensation. The 1794-TB3TS is CSA, CE, and c-UL-us certified, and it has a total dimension of 94mm x 94mm x 69mm (3.7in x 3.7in x 2.7in) with the module installed.
