  • Overview

  • Technical details

  •  

    Advanced features

    • The 5225 transmitter can be configured with a standard PC and the Loop Link communications unit, or delivered fully configured.

    Application

    • The f/I function performs frequency to current and voltage conversion.
    • The f/f function can be used for pulse division or multiplication and as a buffer collecting fast pulse trains.
    • The concurrent f/I and f/f functions enable a scaled digital output signal in conjunction with the analog output.
    • The frequency generator function is used as e.g. a time base or clock generator.
    • Input and supply polarity reversal protection.
    • Current and voltage output signals galvanically separated from the supply and the inputs.
    • Programmable digital outputs including NPN, PNP or relay options.

    Technical characteristics

    • 4 front LEDs, indicating f in active inputs (not NPN), Dig.out.1 (NPN or relay 1) and Dig.out 2 (relay 2) outputs, and a NAMUR input error signal.
    • Analog current output can be configured to any current within 0...20 mA range.
    • Voltage output range is selectable between 0...10 VDC and 0...1 VDC by use of internal jumpers.
    • Programming can be performed with or without a power supply.
