The outside of these two units is one of simplicity. The front face of the red powder coated steel housing features a LED power indicator, adjustment screws for both the sensor span and zero, and a shunt activation button. Screw terminals make connecting equipment simple, with no connectors that need to be crimped and assembled. With all of that, these two new instruments only take up a 0.70 inches of DIN rail space.
The IAA100 features user selectable +/- 5V and +/- 10V outputs while the IAA200 features a 4-20 mA output. To build on the performance improvements of the CSG110, FUTEK split the combined voltage and current amplification capabilities of the CSG110, by designing the IAA100 and IAA200 to only output an amplified voltage and amplified current signal respectively. This hardware split freed up circuit board space allowing the IAA100 and IAA200 to feature:
33% reduction in signal noise
DIP switch selectable signal bandwidths of 1 kHz, 10 kHz, and 25 kHz
Choice of 5V or 10V excitations
Selectable excitation voltages of 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 4.0, 10.0 mV/V via DIP switches
Built in signal offset control
The IAA100 and the IAA200 also feature an externally accessible shunt activation button. The extra board space allows for users of the IAA100 and IAA200 to dial in their desired shunt resistance by toggling on/off an array of built in shunt resistors. FUTEK also eliminated the hassle of activating the shunt by pressing the shunt activation button in a crowded cabinet. Instead the shunt can be remotely activated by applying power to an external shunt activation pin.
