    DIR35

    Process Indicator

    The DIR35 Powered Process Indicator is a 120/240VAC or 12-40VDC powered 3.5 digit (1999 count) process indicator supplied in a panel mount enclosure with a 14.2mm high LED display with 2 alarm set points which can switch 240VAC at 1 amp with 99% dead band. The instrument is rangeable in engineering units for millivolt, milliamp and voltage inputs. Range cards are available for PT100 resistance bulbs. An optional 24VDC at 30mA loop supply is available for the direct connection of 2 wire transmitters.



      • Accepts all standard process signals
      • The DIR35 is user rangeable in engineering units
      • Band gap reference
      • Differential input
      • Low cost - High performance
      • 120 or 240VAC 47-63 Hz supply or factory fitted 12 to 40vdc isolated supply
      • 3.5 digit high brightness LED display of 14mm digit height
      • Decimal point selection
      • Two (2) set point relays with form C contacts
      • Housed in a panel mount enclosure of 48x96mm
      • 24VDC loop supply for loop powered sensors and transmitters
      • Emc compliant (C tick)

      The DIR35 Powered Process Indicators is an advanced instrument that has been designed and manufactured to stringent specifications which accept all the standard analogue process signals.

      The DIR35 provides two (2) 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. Range cards are also available for Rtd.
    • CMRR greater than 86db
    • NMRR greater than 100db
    Displays
