RTD Analog Input Module The AIM6 RTD Analog Input Module provides appropriate signal conditioning for either 1OOQRTDs or AD59O/AC2626 semiconductor temperature sensors. Four input channels are provided. All four channels must be configured for the same type of sensor. The AIM6 module can accept common mode voltages to rtGV Optional resistors convert current output to voltage output for the connection of AD590 and AC2626 temperature sensors. All connections are made to on-card screw terminals. -^^- . The AiM6 module may be piaced in siots 2 through i0 of a 500A or 5UW chassis, or siot 3 of a 575 or 576 chassis. To install the module in a 500A or 5OOP,remove the baseboard top cover and insert it into the desired slot with the component side facing the power supply. To minimize temperature effects from the power supply and to keep noise pickup to a minimum, it is recommended that the AIM6 module be installed as close to the AMM module as possible. Generally, analog modules should be placed in the low-numbered slots while digital modules should be placed in the high-numbered slots to minimize these effects. 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. To min- imize the possibility of EMI radiation, never operate the system with the top cover re- moved. Unused inputs should be connected to module ground. User-Configured Components One bank of screw terminals is provided on the AIM6 module. In addition to high (+>, low (-1 and ground terminals, the AIM6 module has a single terminal to provide a +lOV excitation for AD590/ AC2626 temperature sensors. A potentiometer allows adjustment of the excitation voltage. Table 1.
