The Allen-Bradley 1756-OB8EI is a ControlLogix DC digital output module with 8 points, rated 10-30V DC at 2A sourcing per point. Each output is electronically fused and individually isolated, so a fault or short circuit on one output point trips that channel alone rather than affecting the rest of the module or requiring a hardware fuse to be replaced.

This combination of individual isolation and electronic fusing makes it a common choice where output points are wired to physically separate parts of a machine or process, limiting the blast radius of a single wiring fault.

Field wiring connects through a Removable Terminal Block (RTB) or 1492 interface module (IFM), sold separately. Supplied by Z&F Corporation — our technical sales team can confirm the correct wiring accessory and certification documents for your installation when requesting a quote.
