Allen-Bradley 1734-OB8E – POINT I/O digital output module

The Allen-Bradley 1734-OB8E is an 8-point sourcing (PNP) digital output module used in POINT I/O distributed I/O systems with a 24 V DC supply. It provides discrete output channels for controlling field devices such as indicator lights, relays, solenoids and actuators directly from the I/O network.

Each output channel is sourced to drive external devices at 24 V DC. The module supports output current per point consistent with typical industrial control requirements and includes front-panel LED indicators for status feedback on each channel. Installation is performed through the POINT I/O terminal base on DIN rail, enabling organized wiring and straightforward serviceability.
