About 1794-TBNF

The 1794-TBNF Flex I/O Fussed Terminal Base Unit by Allen-Bradley is a fused terminal base unit which provides 16 I/O connections and comes with 2 common terminals, 2 +V terminals, screw terminals, and a covering for I/O wiring. It has a voltage rating of 250V AC/DC with a maximum current rating of 10A and the base unit has a power rating of 650W. It provides 8 slow blow fuses with a 5 by 20mm fuse size and a fuse rating of 1.6A at 250V AC also provide I/O termination through spring clamp. The 1794-TBNF has a terminal screw torque of 1.4 Nm (12lb-in) and utilizes copper wire with 0.34 x 3.3 mm2 (22/12 AWG) copper wire rated at 75 °C (167 °F) wire size and with 1.2 mm (3/64 in) thick insulation. 
The 1794-TBNF provides a FLEXBUS rating of 640mA at 5V DC, with V/COM terminal voltage of 250V DC/AC at 50-60 Hz and a current of 10A. It is capable of 250V (continuous) maximum voltage isolation between field wiring terminals to FLEXBUS with basic insulation type but the actual isolation voltage depends solely on the installed module. The 1794-TBNF has an operational temperature range around -20-55 °C (-4-131 °F) and is stored at a -40-85 °C (-40-185 °F) temperature range. It has factory-designated T4A (NA) and IEC T4 temperature codes and comes in an open-style enclosure. The 1794-TBNF has a tested and rated operational shock withstand of 30G and can also maintain function at an operational vibration of 5G at 10-500 Hz vibrational frequency.
