Technical data Power supply: 1.5V AA MN 1500 batteries from Duracell
[use 2 batteries connected in series]
Maximum transmission power 282 mW
Contains FCC-ID POOWML-C40
Output circuits in protection type Ex ib IIC for connection to certified intrinsically safe circuits – maximum values
Output supply voltage [pin X1-1] Uo = 5.9 V
RS 232 interface [pins X1-2, X1-3] Uo = + 5.9 V
Maximum output values Io = 200 mA
Po = 1.2 W
Trapezoid characteristic curve
Maximum permissible external
capacitance Co = 30.64 µF
Maximum permissible external
inductance Lo = 2 µH
The given maximum permissible external inductance is defined that according to IEC/EN 60079-11 section 10.1.5,
the total inductance is less than 1% the permissible value established by figure A.6 of IEC/EN 60079-11 and therefore
negligible. For a combination of external capacitance and inductance, the given maximum values are still valid.
