 Intrinsically safety circuit
• Maximum Voltage (Uo): 14 V
• Maximum Current (Io): 17 mA
• Maximum Electrical Power (Po): 0.12 W
 Fluid Temperature: –20 to 130°C
 Ambient Temperature: –20 to 55°C
 Grounding:
Grounding resistance of 10 Ω or less is
necessary for class A grounding terminal.
Grounding resistance of 100 Ω or less is
necessary for Functional grounding terminal.
When the optional code A is selected,
grounding resistance of 10 Ω or less shall be
required.
IMPORTANT
Class A grounding should be installed in non-
hazardrous area.
 Flameproot packing adapter:
The specifying optional code G11 is necessary.
In case of two flameproof packing adapters,
select optional code G32 with G11.
