  • Math Capability Supports Many Process Control Functions.
  • Switch Selectable or PC Programmable Ranges.
The Q498 is a DC powered, DIN rail mount, DC input signal conditioner. The unit is fully isolated to 1800V between input, output and power. Two isolated analog inputs each accept either a DC voltage or current. One analog output delivers either DC bi-polar voltage or uni-polar current. The Q498 also has a separated frequency input channel and a frequency output, as well as a discrete input and output channel.

The Q498 can perform single or double input math calculations on the input values. The available operators are: +, -, *, /, Sq, Sqroot & Average. Process control functions include Hi/Lo Select, Rate of Change Limiter and Track & Hold. The frequency input can also have the math functions applied. A 25-point linearization function is available for Channel 1 Analog input only. All output math and process control functions require the C698 software.
