  • Overview

  • Technical details

  •  

    Application

    • The 3111 temperature converter measures standard TC J and K temperature sensors, and provides an isolated analog voltage or current output.
    • High 3 port isolation provides surge suppression and protects the control system from transients and noise.
    • The 3111 can be mounted in the safe area or in Zone 2 / Division 2 areas.
    • Approved for marine applications.

    Technical characteristics

    • Flexibly powered by 24 VDC (±30%) via power rail or connectors.
    • < 30 ms fast response time with simultaneous sensor error detection when selected.
    • Selectable 300 ms response time when signal dampening is needed.
    • Selectable internal/external CJC.
    • Excellent conversion accuracy in all available ranges, better than 0.05% of span.
    • Meeting the NAMUR NE21 recommendations, the 3111 provides top measurement performance in harsh EMC environments.
    • The device meets the NAMUR NE43 standard defining out of range and sensor error output values.
    • A visible green LED indicates operational status of the unit and the input sensor.
    • All terminals are protected against overvoltage and polarity error.
    • High galvanic isolation of 2.5 kVAC.
    • Excellent signal/noise ratio of > 60 dB.

    Mounting / installation / programming

    • Selectable DIP-settings for easy configuration of more than 1000 factory calibrated measurement ranges.
    • The narrow 6 mm housing allows up to 165 units to be mounted per meter of DIN rail, without any air gap between units.
    • Wide ambient temperature range of -25...+70°C.
