AMMIA Master Analog Measurement Module The AMMl A Analog Measurement Module combines three important Series 500 functions into a sin&e module. First, the AMMlA functions as a standard analog input module, and will accept up to 16 sin- gle-ended or eight differential analog input signals. It contains signal conditioning and switching cir- cuitry for these channels. Second, the Ah&ilA selects and conditions analog signals from other analog input modules in a Series 500 system. Last, the AMMlA serves as a IZbit A/D converter for its own analog input channels, as well as any other analog signals which have been processed by the global se- lect/conditioning circuitry. After analog conditioning, signals are routed to the A/D converter section of the module for the analog-to-digital conversion process. Input signals are applied to the AMMl A's analog input channels through on-card quick-connect screw terminals. The AMMlA has a total of 16 local single-ended, or eight differential inputs. The input con- figuration is controlled through software, rather than with hardware switches. These analog input channels can be conditioned with programmable local gains of either xl or x10. Global conditioning consists of a high-speed software-controlled gain amplifier with programmable xl, x2, x5 and x10 gain values. All analog inputs connected to the Series 500 pass through the global circuit- ry, whether the signals originate on the AMMlA or some other analog input module. Therefore, these gain values can be applied to any analog input in the system. For A/D conversion, the AMMlA uses a E-bit successive approximation converter. A maximum con- version time of only l@ec allows sampling rates as high as 62.5kI-L~. to maximize resolution, the AMMlA has 0-IOV and +lOV A/D converter ranges which are software selectable. CAUTION: Always turn off the system power before installing or removing modules. To minimize the possibility of EMI radiation, always operate the system with the top cover in place and properly secured. The AMMlA is designed to be used only in slot 1 of the 500-series chassis, Model 575, or Model 576. To install the module in a series 500 chassis, first remove the baseboard top cover and install the module in slot 1 with the component side facing the power supply. For Model 575 or 576, please refer to the Set- up section of its hardware manual. Document Number: 501-913-01 Rev. B AMMl A-l TPB TPl3 TPl2TP4 TPlO '61 go 0 *O 0
