Output

Description

4 to 20 Milliamperes (Standard)

• The linear 4 to 20 mA output:

– corresponds to the field-programmed gas range.

– can be calibrated in the field for maximum accuracy.

– is user selectable for isolated or non-isolated use.
Refer to the “Setup ” section for programming information.

4 to 20 mA with Relays (Optional)

• Option includes a set of four relays:

–High Alarm

–Low Alarm

–Auxiliary Alarm

–Fault

• The High, Low and Auxiliary Alarm relays are programmable

as a group for either normally energized or normally de-energized

operation.
• Low Alarm, Auxiliary Alarm, and High Alarm relays are programmable as

a group for either latching or non-latching operation.
• Fault relay is normally energized with no faults. Faults are generally

non-latching, but faults that occur during calibration and warmup must be

reset.
• Latching relays are reset using either the Cal magnet or an external reset

switch (field installed, user supplied).
