AIM2 High-Level Analog Input Module The AIM2 High-level Analog Lnput Module offers 32 channels of analog input, and is designed to accept signals ranging from -lOV to +lOV full scale. Two high-speed multiplexers, controlled from software, select the channel to be measured. A multiplex- er settling time of 4pec preserves system throughput. From the AIM2 module, signals are routed to the AMM (lA, 2, F) Analog Measurement Module in slot 1 of the 5OOA,5OOR 575, or 576 chassis, via a private low-noise pathway. On the AMM module, gain is applied, and the signals are converted via an analog-to-digital converter. Optional resistor locations permit the installation of resistors to ground. All signal connections are made directly to on-card screw terminals. The AIM2 module may be instahed in slots 2-10 of a 5OOAor 500P chassis, or slot 3 of a 575 or 576 chas- sis. To install the module in a 5OOAor5OOP, remove the top cover and insert the board in the desired slot with the components facing the power supply. To minimize the effects of heat and noise from the power supply, it is recommended that analog modules be placed as close to the AMM as possible. Generally, analog modules should be kept as far away from the power supply as possible. For installation into a 575 or 576 chassis, consult the hardware manual for that chassis. CAUTION: Always turn off the system before installing or removing modules. Replace the top cover and secure it with the screws. To minimize the possibility of EM1 radiation, never operate the system with the top cover removed. User-Configured Components Screw terminals and optional resistors are user-configured components on the AIM2 module. Screw ter- minals banks J147 and J148 allow on-card signal connection for analog inputs arriving at the AlM2.32 terminals are provided for signal line connections, and 8 terminals are provided for common ground connection. These terminals accept 16-24 gauge tie. Optional resistor locations permit a resistor connection to ground for each channel. These locations can be used when configuring the module to accept current inputs. These components should be installed on supplied DIP headers. See Table 1 for user-configured components.
