    Display range: -1999 to +9999
    Decimal point: any position selectable
    Scaling: scale freely adjustable via 3 keys at the back side of the unit
    Accuracy: < 0.2% FS ±1 digit (at 25°C)
    Temperature drift: < 100 ppm
    Measuring rate: ca. 5 measurements/s.
    Filter: adjustable:  0.1 bis 2.0, off
    Speicher: min-/max- value memory
    Switching output: electrically isolated open collector
    Switching power: 25VDC/50mA
    Working temperature: -20 to +50 °C
    Storage temperature: -20 to +70 °C
    Electrical connection: 2 x 2-pin screw-type/plug-in terminal,  max. terminal range up to 1.5 mm²
    Gehäuse: fibre-reinforced Noryl
    Front screen: polycarbonate
    Dimensions: 24 x 48 mm (H x W, front dimensions)
    Panel cutout : 21.7+0.5 x 45+0.5 mm (H x W)
    Mounting depth: ca. 65 mm incl. terminal
    Protection rating: IP20, with front flush installation: IP54

    Ex Protection data:
    EC type examination: BVS 11 AtEX 1 333 X
    Connection data: Umax: 28 V
                               Imax: 100 mA
                               Pmax: 1.2 W (for GIA 0420 N -ex
                                         or 0.95 W (for GIA 010 N - ex)
    max. effective internal capacitance: Ci = 13 nF (for GIA 0420 ...)
    additionally for the switching output: Ci = 4.5 nF
    max. effective internal inductance: negligible small

    Please keep in mind for the circuit of the switching output that the wiring has to be done from the same intrinsically safe
    circuit as the measuring signal!
