The ASB803008 collects discrete field signals inside Schneider’s Modicon 800 automation platform. This module measures roughly 9.8 inches long, 1.2 inches wide, and 5.5 inches high. Moreover, it weighs about 0.9 pounds, which suits standard rack mounting. Engineers specify the ASB803008 when they need reliable input acquisition across distributed control cabinets.
Technical Specifications and Interface Details
The unit reads discrete sensor states and therefore supports limit switches, pushbuttons, and relay contacts. Specifically, it provides sixteen input points with defined logic thresholds. Additionally, a keyed edge connector links the module to the host backplane. Front-panel LEDs reveal channel status during operation and troubleshooting.

Energy Storage and Signal Conditioning
Internal capacitors on the ASB803008 provide local energy storage for clean input thresholds. Consequently, the module rejects electrical noise from motors and contactors nearby. This filtering keeps logic readings stable in demanding plant environments. The input stages therefore respond consistently across repeated switching cycles.
Installation and Compatibility Notes
Because the ASB803008 slides into standard Modicon 800 racks, technicians complete replacement in minutes. They should confirm connector alignment before they apply power. Furthermore, routine inspection of edge contacts prevents intermittent signal faults. Always store spare modules in anti-static packaging to protect sensitive components.
