• SIL 2 according to IEC 61508; SIL 3 in a

This device is a single-channel, galvanically isolated

intrinsic safety barrier that transfers discrete signals

(NAMUR sensors/mechanical contacts) from a hazardous

area to a safe area. The proximity sensor or switch controls

a form C relay contact for the safe area load. The barrier

output changes state when the input signal changes state.

This output state can be reversed through the mode of

operation switch S1.

For a mechanical contact, LB monitoring can be selected

by placing a 10 kΩ resistor across the mechanical contact

in the field and moving switch S3 to position I on the

barrier. SC monitoring is added by placing a 400Ω-2 kΩ

resistor in series with the mechanical contact. NAMUR

proximity sensors, however, are designed with the LB and

SC functions, making external resistors unnecessary. In

case of a LB/SC fault, the signal output relay reverts to the

deenergized state. LB/SC monitoring can be disabled with

S3 in position II.
