The DIR4WP powered process indicator is a large 4 digit (9999 count) for clear viewing from a distance utilised for measuring a wide variety of levels, from pressure levels to fuel, and everything in between. An optional 24VDC at 30mA loop supply is available for the direct connection of 2 wire transmitters. The instrument is supplied in a surface mounting weatherproof enclosure with a 57mm high LED display.

The DIR4WP Powered Process Indicator is an advanced instruments which has been designed and manufactured to stringent specifications.

The instruments have been designed to accept all the standard analogue process signals. The input measurement is shown on a high contrast LED display.

The DIR4WP incorporates an LSI CMOS 20000 count dual slope integrating analogue to digital converter which is designed to reject electrical interferance that normally abounds in industrial environments. The front panel of the DIR4WP series are sealed to IP65 and includes screw terminal electrical connection.

TECHNICAL SPECIFICATIONS

Input Details
