About 1794-TB3GS

The 1794-TB3GS Grounded Spring Clamp Terminal Base Unit Module by Allen-Bradley is a 36 I/O point terminal base unit installed with a DIN Rail or a panel mount on the adjacent side of an I/O adapter and which establishes connection points for input/output wiring. When connected with other base units it forms the backplane of a device. It has an I/O connection capacity of 36 and it has 2 common terminals 2 +V voltage terminals and 10 chassis ground terminals. It is designed specifically for applications with up to 31.2V DC and with a maximum 2A current. The 1794-TB3GS has a power supply rating of 5V DC and 640mA (Flexbus) with an input/output terminal current of 2A and has a V/COM Terminal rating of 10A at 31.1AC/DC at 50-60Hz. 
The module provides 50V (continuous) isolation between Field Wiring Terminals to FLEXBUS tested for 60 seconds at 2121V DC and I/O termination is provided using the Grounded Spring Clamp. The 1794-TB3GS has a functioning temperature range between -20 and 70 °C (-4 and 158 °F) with a relative humidity range of 5-95% non-condensing and a temperature range of -40-85 °C (-40-185 °F). It has a T4A temperature code and an IEC T4A Temperature code and comes in an open-style enclosure. It can withstand a shock of 30G when operational and can maintain its function at a vibration of 2G.
