Specifications

Input Voltage 24 VDC nominal. Operating range is 18 to 32 VDC

including ripple.

Power Consumption 4.0 watts nominal @ 24 VDC

7.5 watts maximum @ 24 VDC

10 watts maximum @ 32 VDC.

Short Circuit Current Isc: 5.4 amperes.

Isc (fuse): 3.1 amperes.

Warmup Time Two minutes from cold power-up to normal mode;

1 hour minimum recommended.

Current Output Linear 4 to 20 mA (current source/sink, isolated/nonisolated)

rated at 600 ohms maximum loop

resistance @ 24 VDC operating voltage.

Detection Range 0 to 100% LEL standard.

Other ranges are configurable.

Detectable Gases Most flammable hydrocarbon vapors are detectable.

Standard gases include methane, ethane, ethylene,

propane, butane and propylene. Detection of nonstandard

gases is configurable using the HC275

HART communicator.

Calibration All units are methane-calibrated at the factory.

Device configuration is required for detection of

vapors other than methane.

Device Configuration Configuration parameters include tag number,

measurement range, signal processing algorithm,

alarm levels, and other selectable parameters.
