S upply and signal circuit
Terminal no. 1[+], no. 2[-] In ignition protection type intrinsic safety EEx ia
IIC/IIB
Only for connection to a certified intrinsically
safe circuit.
Maximum values:
Ui = 20 V
Ii = 103 mA
Pi = 516 mW
Li = negligibly small
Ci = negligibly small
The intrinsically safe circuits are electrically separated from parts which can be grounded.
For applications requiring instruments of category 2G or 1/2G, the intrinsically safe power
supply and signal circuit can correspond to protection class ia or ib. For connection to a circuit
of category ib, the ignition protection type identification is EEx ib IIC T6.
T ip:
Ignition protection type identification: II 2G EEx ia IIB T6, II 2G EEx ib IIB T6 resp. II 1/
2G EE
x ia IIB T6 in case of power supply via a circuit of group IIB.
