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.
