Redundancy Evaluator
AD-RA 300 GVF

For important analogue values it must be considered that a measuring value can also be incorrect if it is inside the admissible measuring range. Such an error can be determined through redundancy measuring, here three analogue values are measured and a mean value is obtained. If the difference between the channels exceed a user-defined limit, the deviating input is reported via a potential-free relay and is at the same time excluded from the averaging. Consequently a secure analogue signal continues to be present at the output. If more than one channel deviates, the output is set to the measuring range start and all relays report an error. All necessary parameters can be configured directly at the device or via a PC software AD-Studio.

TOP-characteristics:
  • 3 current inputs (bipolar)
  • the deviating input is reported via a respective potential-free relay
  • current and voltage input are freely scalable and simultaneously operational
  • multicoloured (RGB) illuminated LCD display
  • simulation mode (auto/manual)
