Description
The 1794-TB3K, produced by Allen Bradley, serves as a terminal base specifically within the Flex I/O 1794 series. Engineered for reliable performance, it features a cage clamp terminal type, providing secure connections for multiple input lines. This terminal base supports a total of 16 input connections, allowing it to efficiently manage various signal transmissions within industrial setups.
With an operational temperature range from -20 to 70 degrees Celsius, the 1794-TB3K is suitable for a range of environments. It can handle a maximum FlexBus supply voltage rating of 5V DC and a supply current of up to 640 mA. The terminal base also supports a terminal supply voltage rating of 2 A, offering adequate power for connected devices.
The maximum voltage ratings for V/COM terminals include ratings of 125V AC/DC at 50/60 Hertz with a current capacity of 10 A, or 60V AC at 50/60 Hertz/ and 75V DC for specific compliance standards (ATEX, UKEX, IECEx). Continuous isolation voltage is maintained at 125V using basic insulation, ensuring safe operation in varied conditions.
In terms of dimensions, this terminal base measures approximately 94 x 94 x 69 mm when a module is installed. For environmental resilience, the 1794-TB3K can withstand operational shock ratings up to 30 g, as well as non-operational shock ratings of 50 g. This combination of features makes it a robust choice for applications in industrial automation environments.
