About 1794-TB3S

The 1794-TB3S Flex I/O Terminal Base Unit by Allen-Bradley is a 16 I/O capacity terminal base unit module with eighteen common terminals and eighteen voltage terminals used in applications with up to 125V AC/DC rating. The module has a current of 10A (max) and provides a Flexbus current of 640mA at 5V DC and a 2A current across the input/output terminals. The 1794-TB3S also provides 125V AC/DC voltage and 10A current at 50-60Hz across the voltage/COM terminals. It can provide 125V isolation voltage between Field-Wiring-to-FLEXBUS employing the Basic Insulation type and it enables I/O termination using the spring clamp termination type. 
The 1794-TB3S uses copper wire with 0.34 x 3.3mm2 stranded or solid wire rated at 167 °F and with a 1.2 mm (3/64 in) thick insulation as its base circuit cable and the module has a shipping dimension of 94mm x 94mm x 69mm. Like most terminal base in the Flex I/O series, it is given the T4A (North America) and T4 IEC temperature code for maintaining function at a maximum temperature of 135 0C and it has a factory-defined operational temperature limit between -20 and 70 °C (-4 and 158 °F) at 5-95% non-condensing humidity. It is IEC-tested to functionally resist an operational vibration of 2G at 10-500Hz and it is also tested to operate without de-rating at a shock of 30G. The 1794-TB3S is UL, CSA, CE, and Ex-certified.
