(I) • When combined with Trapezoidal or Rectangular output characteristic FISCO model IIB barrier Ui = 17.5 V, Ii = 460 mA, Pi = 5.32 W, Ci = 1.76 nF, Li = 0 µH ATEX Certification (1) Technical Data a. ATEX Intrinsically Safe Type Caution for ATEX Intrinsically safe type. Note 1. EJX series pressure transmitters with optional code /KS25 for potentially explosive atmospheres: • No. KEMA 04ATEX1116 X • Applicable Standard: EN 50014, EN 50020, EN 50284, EN50281-1-1 Note 2.
The criterion for such interconnection is that the voltage (Ui), the current (Ii) and the power (Pi), which intrinsically safe apparatus can receive, must be equal or greater than the voltage (Uo), the current (Io) and the power (Po) which can be provided by the associated apparatus (supply unit).
Electrical Data • When combined with Trapezoidal output characteristic FISCO model IIC barrier [Supply/Output circuit (terminals + and –)] Ui = 17.5 V, Ii = 380 mA, Pi = 5.32 W, Ci = 1.76 nF, Li = 0 µH [Temperature sensor circuit] Uo = 7.63 V, Io = 3.85 mA, Po = 8 mW, Co = 4.8 µF, Lo = 100 mH • When combined with Linear characteristic barrier [Supply/Output circuit (terminals + and -)] Ui = 24.0 V, Ii = 250 mA, Pi = 1.2 W, Ci = 1.76 nF, Li = 0 µH [Temperature sensor circuit] Uo = 7.63 V, Io = 3.
Supply unit I.S. values Power supply-field device: The supply unit must be certified by a Notified body as FISCO model and following trapezoidal or rectangular output characteristic is used. Po ≤ Pi, Uo ≤ Ui, Io ≤ Ii Calculation of max. allowed cable length: Ccable ≤ Co – ∑Ci – ∑Ci (Terminator) Lcable ≤ Lo – ∑Li Uo = 14...17.5 V (I.S. maximum value) Io based on spark test result or other assessment, No specification of Lo and Co is required on the certificate or label.
Note 4. Operation • Keep the “WARNING” label attached to the transmitter. WARNING: AFTER DE-ENERGIZING, DELAY 5 MINUTES BEFORE OPENING. WHEN THE AMBIENT TEMP.≥65°C, USE HEAT-RESISTING CABLES≥90°C. • Take care not to generate mechanical sparking when accessing the instrument and peripheral devices in hazardous location. Note 5.
