    DIR4WP

    Process Indicator

    The DIR4WP Powered Process Indicator is a 85 to 250 VAC or 12-40 VDC powered microprocessor based indicator that incorporates a four (4) digit 57mm digit height LED display in a weatherproof surface mount enclosure with four set points that can switch 240VAC at one ampere resistive. The instrument is touch witch programmable from the front panel for input range, relay operation and display intensity.



    • Accepts all standard process signals
    • Digital instrument with touch switch programming of all functions - input range, relay on and off point, high or low alarm, and decimal point position
    • Non-volatile storage of variables
    • Differential input
    • Low cost - High performance
    • 85 to 250VAC 47-63 Hz supply or factory fitted 12 to 40vdc supply
    • 4 digit high brightness LED display of 57mm digit height
    • Decimal point programming
    • Four (4) set point relays with form C contacts
    • IP65 surface mount enclosure of 140mm high x 230mm wide x 95mm deep
    • 24VDC loop supply for loop powered sensors and transmitters.

    The DIR4WP Powered Process Indicator is an advanced instrument which has been designed and manufactured to stringent specifications which accept all the standard analogue process signals.

    The DIR4WP provides four (4) set point relays with 99% dead band. All the set point relays have changeover contacts and will switch one amp at 240VAC resistive. Screw terminal electrical connection by two part plug connectors allows simple connection and disconnection.

    Input Details

    The instrument has a bipolar differential input. To realise the accuracy a temperature compensated band gap reference is used in the radiometric measurement system. Full scale ranges of 20 MV to 200VDC 200uA to 2 Amps and 4-20mA are acceptable.

    Displays

    DIR4WP: A 4 digit high contrast light emitting diode (LED) of 57mm digit height with a wide viewing angle and a reading rate of 4 per second. The display intensity is programmable from the front panel. The digits have a viewing distance of 25 metres.

    Decimal Points

    DIR4WP: Four (4) position user programmable from the front panel.

    Relay Outputs

    DIR4WP: Four (4) switch point relays are provided with form C contacts rated at 240VAC one (5) ampere resistive.

    Instrument Power Supply

    85 to 250VAC 47-63 Hz or factory fitted DC to DC converter isolator from 12 to 40VDC.

    Transducer Power Supply

    A 24VDC at 30mA transducer power supply is incorporated in the instrument.
