Specification

The 1794-TB32S is an Allen-Bradley 32-channel spring terminal base unit designed for use with Flex I/O systems. This base provides a robust and reliable interface for discrete input and output modules, such as the 1794-IB32 and 1794-OB32 series. Its spring-clamp technology eliminates the need for screwdrivers, enabling rapid wiring and reducing labor costs in high-density applications. The 1794-TB32S is engineered for harsh industrial conditions, offering vibration resistance and secure connections that prevent loosening over time. Compatible with standard Flex I/O backplanes, it supports both AC and DC module variants, making it a versatile choice for process control, manufacturing, and automation systems. Each unit is factory-tested and shipped as new, ensuring immediate deployment in critical control loops.
