IntelliPack math modules perform complex mathematical computations and convert DC input signals to scaled DC or frequency outputs. They are ideal for isolating and interfacing analog signals to a PLC or controller as a voltage, current, or a pulsed input. Typical applications include calculating a sum, delta’s, average, flow rate, volume, weight, power, and other scaled or computed variables. Math modules are available with either DC voltage/current output or frequency/pulse-width modulated output. Each output (DC, frequency, and relay channels) is controlled by a unique, user defined equation. The math/computation equations are entered into the IntelliPack configuration software in a free form format, the same as in most popular spreadsheet programs. A simulator screen provides instant feedback to test equations and see the output response before actual installation.
