Appendix A. AM16/32 Improvements
The AM16/32 provides the panel switch option of operating in one of two
modes.
• “4X16” mode - Sixteen channels of four simultaneously enabled terminals
(SETs).
• “2X32” mode - Thirty-two channels of two SETs.
The AM16/32 is designed to do a “break before make” meaning that it
advances channels with no momentary connection of the present channel’s
sensor inputs with the next channel’s sensor inputs.
The AM16/32 is smaller than the AM416 and AM32 allowing placement of
two multiplexers inside a single AM ENC enclosure.
The AM16/32 includes an aluminum cover plate which reduces thermal
gradients if used for thermocouple measurement. The cover also helps protect
terminals from dust and improves wiring layout and appearance.
