is inv aid

intrinsic

safety

explosion

protection

systems, isolating barrier belongs to affiliated

device. It is installed at safe area, as a

connection between intrinsic safety devices in

the hazardous area and non-intrinsic safety

devices in the safe area. By limiting the energy

to a certain safe amount, it ensures the safety

of in spot devices and people.

Selection regulations for intrinsic safety

explosion protection system:

1． The explosion protection grade of the

barrier must be equal to or higher than

that of in spot intrinsic safety explosion

protection device.

2． Take inconsideration of hazardous end

output resistance and loop resistance,

make sure the barrier

’s output voltage

meets the minimum operation voltage

requirement of in spot intrinsic safety

device.

3． The

safety

parameters

Barrier

’s

intrinsic safety end meets:

≤ UI, Io ≤ Iin, Po ≤ Pin

≥ Cin, Lo ≥ Lin

4． Select

suitable

Safety

barrier

which

matches the in spot intrinsic safety device

for the power

’s phase, signal type and

transmission mode.

5． Apply

necessary

protections,

avoid

influence the in spot intrinsic safety

device

’s operation from leakage current

that generated by safety barrier.
