Product description:

Input Voltage 24 vdc. Operating range is 18 to 32 vdc including ripple.

Power Consumption 5 watts nominal, 7 watts maximum.

Current Output Linear 4 to 20 ma current source (non-isolated)

4 to 20 ma output indicates 0 to 100% LFL

detection range (standard)

23.2 ma indicates over-range condition (120% LFL)

0 to 2.4 ma levels indicate calibration, fault and

fouled optics conditions.

Detection Range 0 to 100% LFL.

Gases Methane, Ethane, Propane, Butane, Ethylene,

Propylene

All devices are shipped with 0 to 100% LFL linear

output for methane.

0 to 100% LFL outputs for the above standard

gases are switch-selectable and can be set in

the field.

Response to other gases/vapors available.
