892M, 894M Math Module with DC Voltage / Current Output Description
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.
