Isolated Low-Level Analog Input Module
The AIM5 Isolated Low-level Analog Input Module is designed to accept inputs from
+5mV to *lOOmV, including signals from thermocouples. Isolated input permits the
connection of signals with high common mode voltages--up to 500V DC or peak AC--
and provides normal mode input protection up to l3OV. Channel-to-chaimel isolation is
500V DC or peak AC. The input bandwidth is below 2Hz, reducing sensitivity to 50/60
cycle AC noise.
There are four input channels on the AIM5 module, each with individually adjustable
gain amplification. The module is shipped from the factory with a preset gain of xl00
volts/volt, appropriate for thermocouple types B,E,J,K,R,S, and T. This gain can be reset
for each channel by changing the value of the gain-setting resistor.
The AIM5 is equipped with cold junction reference circuitry, which al|
