PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1794-TB3S is a FLEX I/O terminal base unit designed for industrial control systems. This unit supports up to 16 input and output channels for connected field devices. It provides spring clamp terminations for circuit wiring. The unit carries a maximum current rating of 10 A. The terminal base operates with supply voltage ratings of 24V DC/AC and 120V DC/AC.
This terminal base unit accepts conductor sizes ranging from 22 to 12 AWG. The equivalent metric wire range is 0.34 mm² to 3.3 mm². The unit operates in ambient temperatures from -20 to 70 degrees Celsius. Storage temperature tolerance spans from -20 to 85 degrees Celsius. The unit tolerates non-condensing relative humidity levels between 5% and 95%. Operational vibration resistance is rated at 5 g from 10 Hz to 150 Hz.
