Product Introduction
The 30731823-001 Azbil Robust A/D Multiplexer Card (ARMUX) is an input card used in the common card fi le. 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 redesigned version of the original A/D Mux card based on the latest technology. With the replacement of older, limited-life technology by today's state of the art technologies, users of these products can be assured of long-term support and a more robust control system.

Product Details
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 supports Data Hiway user requirements for economical continuation of process control and process interface functions that are crucial for safe and stable process plant operations. The ARMUX provides the following specifi c benefi ts:
- Calibration-free Plug and Play replacement for the original analog input card
- Design incorporating new technology, 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 tolerance to environmental conditions due to conformal coating
