Selection guidelines for intrinsically safe explosion protection system

1.The explosion protection grade of the barrier must be not less than that of intrinsically safe explosion protection device in spot.

2.Take inconsideration of hazardous end output resistance and loop resistance make sure the barrier output voltage meets the minimum

operation voltage requirement of intrinsically safe device in spot.

3.The safety parameters about intrinsically safe end meets:

Uo

≤ UI, Io ≤ Iin, Po ≤ Pin

Cc

≤ Co-Ci, Lc ≤ Lo-Li

4.Select suitable safety barrier which matches the intrinsically safe device in spot according to the power polarity, signal type and transmission

mode about the device.

5.Much more protection is required, which can avoid the influence of the leakage current generated by safety barrier on intrinsically safe device

in spot.

6. The wires leading to dangerous field should be constrainted in blue intrinsically safe wires, and its copper cross-section should be more than

Note: When use bottom power suppl y, anyone group or both i s OK.

Pins 1, 2, 3, 4, 5, and 6 are in the field area, belong to the dangerous

side, use blue terminals;

Pin 7, 8, 9, 10, 11 and 12 are in the control area, belong to the safe

side, use green terminals
