About 1794-TB3SA

The 1794-TB3SA Flex Terminal Base unit by Allen-Bradley is a 3-wire spring clamp terminal base module with a 16 I/O capacity, 18 common terminals, and 18 +V voltage terminals. It is compatible with applications using a 125V AC/DC voltage rating and it has a maximum current rating of 10A. The spring clamp allows for faster and easier wire installation and the module in conjunction with other terminal base units constitutes the backplane of a larger device. The module has a Flexbus rating of 5V DC at 640 mA and provides 2A current along the I/O terminals connected to it. The 1794-TB3SA circuit utilizes copper wire with 0.34 by 3.3 mm2 (22/12 AWG) solid or stranded wire size rated at 75 °C and it provides voltage isolation corresponding to the modules installed on it. The module is mounted vertically or horizontally using a DIN Rail or a panel mount and it has a T4A and T4 (135 0C maximum temperature) temperature code. The 1794-TB3SA has -20-70 °C working temperature range with 5-95% humidity range and when it is not in use, it is stored at a temperature range of -40-85 °C (-40-185 °F). The 1794-TB3SA has an operational shock withstand of 30G and a 2G vibration at 10-500 Hertz and the module is c-UL-us, CSA, and IEC-certified.
