The UniPak™ UP494 is a dual dc input, single dc output module with the ability to be an adder or a subtractor. The UP494
performs percentage math, i.e.: %A +%B = Output or %A - %B = Output. The UP494 can be adjusted, using the front
mounted trim potentiometers to provide a proportional output when the input signals represent non-equal quantities. The
UP494 provides 1500 V isolation between the input, output and power. The exceptional flexibility of the UP494 includes the
ability to provide power 2 of the 3 signal ports. It can provide power to input sensors and be wired as a two-wire transmitter
on the output or it can accept active signals on the input and provide a sourced output as a four-wire transmitter.
Signal Conditioning flexibility and use made simple from ioSelect, powered by Seneca (Z190)
