PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1794-TB32 is a FLEX I/O Flex I/O Terminal Base designed for industrial automation systems. It provides thirty-two input and output connections along with eight common and eight positive voltage terminals. The unit operates at a nominal rating of 24 VDC. Its operating supply voltage range extends from 19.2 to 31.2 VDC.
The terminal base features cage clamp connections for field signal wiring. It provides a Flexbus output current of 640 mA to support connected modules. Continuous isolation voltage is rated at 50 V. Operating ambient temperatures span from -20 to 70 degrees Celsius. Field wiring terminals accommodate conductors from 0.21 to 1.3 square millimeters.
