Sensor

A safety barrier must be installed for the intrinsic safety.

The safety barrier must meet the Ex-data of this unit and must be approved for the hazardous location.

Optional

Be sure to earth the unit’s enclosure to meet the intrinsically safe or explosion-proof (flameproof) requirements.

Close across the terminals 1 & 2 for a resistance or RTD input.

Limited to 250 – 1100Ω for HART communication.
