  • Universal plant standard: With programmable input/output parameters, and “Universal” DC or AC power input, there’s no need to stock dozens of different alarm trips.
  • 20-bit input resolution: Delivers industry best digital accuracy for both sensor (RTD and thermocouple) and analog (current/voltage) inputs.
  • Site- and PC-Programmable: Featuring security password protection, the SPA² offers the choice of using front panel pushbuttons or our FREE Windows®-based Intelligent PC Configuration Software for fast and simple set up.
  • Long-term stability: Provides up to 5 years between scheduled calibrations.
  • Large 5-digit process and status readout: A backlit display shows menu prompts during pushbutton configuration and, when the SPA² is in operation, shows the process variable, the output or toggles between the two in selectable engineering units.
  • Combined alarm trip and transmitter: The analog output (-AO) option reduces costs and installation time when both alarm and transmitter functions are needed at the same location.
  • Isolated and RFI/EMI protection: Delivers superior protection against the effects of ground loops and plant noise.
