AIM7 Thermocouple Input Module The AIM7 Thermocouple Input Module accepts signals The AIM7 may be placed in slots Z-10 of the system from thermocouple tyies J, K, S, T, B, E, and Rior generic baseboard. However, to minimize power supply thermal voltages up to L-1OOmVfull scale. The AIM7 offers 16 and noise effects, the ATM7 should be placed in the lowest channels of differential input, as well as guard and ground numbered available slot. To install the AlM7 in a Model screw terminals. 5OOA,5OOP, 556, remove the baseboard top cover and or place the module in the desired slot with the component side facing the power supply. For the Model 570 or 575, The AIM7 provides channel selection through on-card open the system clamshell cover and place the module in multiplexing. Gain is fixed at 100 volts/volt.

Always operate the system with the conversion. top cover in place to minimize the possibility of EM1 radiation. All thermocouple inputs are applied to screw terminals located on an isothermal block to minimize errors caused User Configured Components by temperature differences between the input connectors and the reference junction sensor. The cold junction refer- ence sensor itself is mounted in the isothermal block to The signal input screw terminals located on the isothermal accurately measure the temperature of the block. In addi- block are the only user-configured components on the tion, a driven guard connection has been provided for the AIM7 module. For the location of these terminals, refer to connection of signal shields. Guarding can minimize the Figure 1. Note that the terminals provide connections for noise picked up by signal input lines. the
