AI845 performs the documented analog input module function within the Advant S800 I/O platform. Verified product data includes Signal specification 0..20mA, 4..20 mA, 0..5 V, 1..5 V; Number of channels 8; Signal type Unipolar single ended; Redundancy Yes; Resolution 12 bit; Input impedance 10 MΩ (voltage input) 250 Ω (current input). These values and the complete hardware revision must match the supplied unit.
Integrate AI845 only with the approved Advant S800 I/O receiving hardware, connector or terminal arrangement and paired assemblies. Preserve all recorded settings, then verify each affected interface and diagnostic path after installation.
Before energizing AI845, inspect mounting, connector keying, wiring allocation, protective grounding and connected equipment. Review status indications and diagnostics, then complete controlled functional tests before service release.
