The 1794-TB3 is a Flex I/O module manufactured by Allen-Bradley. This component is specifically used as a terminal base unit, primarily as an endpoint for field equipment and power supply equipment. The module is also designed to host Flex I/O modules, include 1794-IA8, 1794-IA8I, 1794-IA16, 1794-OA8, 1794-OA8I, 1794-OA16, 1794-IB8, 1794-IB16XT, 1794-IB10XOB6, 1794-IB10XOB6XT, 1794-IC16, 1 794-IG16, 1794-IH16, 1794-IV16, 1794-OB8, 1794-OB8EP, 1794-OB8EPXT, 1794-OB16, 1794-OB16D, 1794-OB16P, 1794-OB16PXT, 1794-OC16, 1794-OG16, 1794-OV16, 1794-OV16P, 1794-OW8, and 1794-OW8XT. The 1794-TB3 has three (3) terminal blocks. The top terminal block consists of sixteen (16) terminals specifically for wiring input and output signals. The middle and bottom terminals consist of eighteen (18) terminals for common terminals and voltage terminals, respectively. -V Common is located in Terminals B-16 and B-33; The +V (voltage input) terminals are located on the C-34 and C-5 terminals. To daisy-chain to nearby Flex I/O modules and terminal bases, daisy-chain terminals are located at C-34 (+) and B-16 (-) for power input and C-51 (+) and B-33 (-) for power supply. The 1794-TB3 has screw clamp terminals. To install the terminal base, place the terminal base in a slightly inclined direction. Hang the terminal base over the top of the DIN rail and connect the back of the terminal base to the DIN rail. The terminal base hook must slide below the edge of the adapter module and the FlexBus connector must be engaged. Slide the terminal base and push tightly onto the adjacent adapter. To lock the terminal base to the DIN rail, push the terminal base until the 1794-TB3 is aligned and engaged to the DIN rail.
Allen-Bradley's 1794-TB3 Flex I/O Terminal base unit is a device that provides terminal connection points for I/O wiring and helps form a backplane. It has up to 16 I/O connections, with 18 common terminals and 18 voltage terminals. The 1794-TB3 is used in applications with a 125V AC/DC electrical rating with a maximum current capacity of 10A and uses 0.21 x 1.3 mm2 (24-16 AWG) stranded copper wire for input and output modules. The 1794-TB3 has a Flexbus rating of 5V DC/640mA and provides 2A current to the I/O terminals. It also has 125V DC/AC and 10A (50-60Hz) V/COM terminal ratings.
The 1794-TB3 provides 125V (continuous) voltage isolation between the field terminals of the FLEXBUS using a basic insulation type with a terminal screw torque of 0.56 x 0.79 Nm (5 x 7lb-in). It has a temperature code specified by T4A (North America) and an IEC T4 temperature code. The 1794-TB3 has an IEC rated operating temperature of -4-158 ° C (-5-95 ° F) at 20-70% non-condensing relative humidity and is tested and rated to withstand 30G operating shock and 500G vibration at 5-10Hz. The 1794-TB3 is c-UL-us, UL, CSA, and CE certified with dimensions of 94 mm x 94 mm x 69 mm (3.7 "x 3.7" x 2.7 ").
