The Allen-Bradley 1794-IB32 module, a part of the Flex I/O family, serves as a robust input interface to seamlessly connect up to 32 DC input devices, such as pushbuttons and sensors, into automated control systems. This high-density, 32-channel current sinking module supports a nominal on-state voltage of 24VDC and accommodates voltage levels ranging from 19.2VDC to 31.2VDC. Designed for integration with various Flex I/O communication adapters, it offers real-time channel monitoring via dedicated LED indicators for each channel, ensuring efficient diagnostics and system verification. The module is compatible with several terminal bases, enabling hot-swapping capabilities and maximizing installation flexibility. It provides reliable isolation between the system and field sides, operating within a temperature range of 0 to 55 degrees Celsius and enduring tough environmental conditions.
