ABB AI830 Analog Input Module (3BSE008518R1)

Product Description

The ABB AI830 (3BSE008518R1) is a reliable analog input module designed for stable signal acquisition in demanding industrial environments. It works with AC800M controllers used in ABB’s 800xA DCS, allowing plants to integrate temperature and resistance measurements into the control system with consistent accuracy. Moreover, the module supports Pt100, Ni100/120, Cu10, and several resistance-based sensors, which enables flexible deployment across mixed process units.

The design maintains a predictable measurement response even when installed near electrical noise sources, therefore helping operators achieve dependable process control. In addition, its 50 V rated isolation improves channel protection and safeguards downstream hardware. Plants transitioning from legacy ABB systems continue to adopt this module due to its stable performance and long-term field reliability, although the AI830 has now been officially replaced by the newer AI830A.

Compatibility with TU810, TU812, TU814, and TU830 termination units ensures easy integration for existing cabinets. For instance, upgrade projects in brownfield facilities often use the AI830 as a direct electrical replacement without altering field wiring. This reduces downtime and maintains operational continuity during phased modernization.
