PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1794-TB3GS is a FLEX I/O Terminal Base Unit designed for the FLEX I/O platform. This unit provides signal routing and power distribution for compatible modules. It features thirty-six spring clamp I/O terminals for field connections. Two dedicated common terminals and two voltage terminals facilitate power distribution. The base supports a nominal operating voltage of 24 V AC/DC. It handles a maximum continuous input current of up to 10.0 A.
The assembly features an open-style enclosure with an IP20 protection rating. Users can mount this unit directly on a standard DIN rail. Spring clamp terminals accommodate wire conductor sizes from 0.34 to 3.3 mm². Maximum supply voltage reaches 31.2 V AC/DC at 50/60 Hz. The terminal base provides continuous isolation voltage rated up to 50 V. Physical dimensions measure 94 mm by 94 mm by 69 mm.
