AMMI F Master Analog Measurement Module TheAMMlFAnaIogMeasurementModuIecombinesthree CAUTION important Series 500 functions into a single module. First, Always turn off the system power before in- the AMMlF functions as a standard analog input module, stalling or removing modules. To minimize and wiII accept up to 16 single-ended or eight differential the possibility of EMI radiation, always operate analog input signals. It contains signal conditioning and the system with the top cover in place and switching circuitry for these channels. Second, the AMMlF properly secured. selects and conditions analog signals from other analog input models in a Series 500. Last the AMMlF serves as a 12-bit A/D converter for its own analog input channels, as The AMMlF is designed to be used only in slot 1 of the 500- well as any other analog signals which have been pro- series system baseboard.

High-speed Acquisition Mode with AMMl F and ANINQ (SOFT500 and QUICK500) Input signals are applied to the AMMlF's analog input channels through on-card quick-connect screw terminals. The ANINQ command can operate the AMMlF module in The AMMlF has a total of 16 local single-ended, or eight high-speed "auto-acquire" mode at an aggregated differential inputs. The input configuration is controlled throughput rate of up to 1OOkHz.Auto-acquire applies to through software, rather than with hardware switches. single or multiple channels.

AlI analog inputs connected to the AMMlE Other modules wiII give inaccurate results due to Series 500 pass through the global circuitry, whether the slower settling times. signals originate on the AMMlF or some other analog input module. Therefore, these gain values can be applied to any analog input in the system. To operate the AMMlF in auto-acquire mode, you must satisfy the following requirements: For A
