Allen-Bradley 1734-IB8 – POINT I/O digital input module

The Allen-Bradley 1734-IB8 is an 8-point sinking (NPN) digital input module designed for use in POINT I/O distributed I/O systems with a 24 V DC supply. It provides discrete input channels for monitoring sensor and switch signals, supporting integration with PLC control architectures.

Each input channel is sinking type, intended to interface with sourcing field devices operating at 24 V DC. The module includes front-panel LED indicators for each input point, allowing visual confirmation of input status during operation and troubleshooting. Mounting is performed via the POINT I/O terminal base and DIN-rail infrastructure, ensuring reliable electrical connections and organized wiring.
