The Allen-Bradley 1734-IB8 is an 8-channel 24V DC sinking digital input module, part of the POINT I/O product family (Series C). Designed for industrial automation systems, it connects field devices (e.g., sensors, switches) to control systems via the POINT bus, supporting flexible DIN-rail mounting (requires a compatible 1734-TB/TBS base).
