Product:Honeywell 30731823-001 A/D MUX CB/EC Primary and Reserve Controller

The azbil Robust A/D Mux Card (ARMux) is an input card used in the common card file. The ARMux can be used in both primary and reserve controllers of the Basic (CB), Extended (EC) and Multifunction (MC) controllers. The original analog input cards used in these controllers have well known design and component availability issues. The new ARMux is a current technologies based re-design of the original input card. By replacing older, limited life technology with today’s state of the art technologies, users of these products are assured of long term support and a more robust control system.

The ARMux provides sixteen input circuits that are equivalent to the original design (8 PV / 8 RV) and is compatible with other board types used within these controllers (see note concerning UCIO).

The ARMux provides the following specific benefits:

 Calibration free Plug and Play replacement for the original analog input card

 New technology design with improved internal diagnostics and status indication via onboard LEDs

 Power on self-test including auto zero and input high calibration

 Continuous zero calibration prior to A/D conversion to eliminate temperature drift

 MTBF increased 5X

 Power consumption reduced 4X

 Improved environmental tolerance due to conformal coating
