HART temperature converter 3113

3113

The 3113 temperature converter measures a standard Pt100, TC J and K temperature sensor, and provides an isolated active analog current and HART signal output.
High 3 port isolation provides surge suppression and protects the control system from transients and noise.
The 3113 can be mounted in the safe area or in Zone 2 / Division 2 areas.
Approved for marine applications.

Flexibly powered by 24 VDC (±30%) via power rail or connectors.
A 60 ms fast response time with simultaneous sensor error detection when selected.
Selectable internal/external CJC.
Excellent conversion accuracy in all available ranges, better than 0.05% of span.
Meeting the NAMUR NE21 recommendations, the 3113 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.

Selectable HART mode with HART 7 revision protocol enables extended device programming.
Selectable DIP-mode for easy configuration of more than 1000 factory calibrated measurement ranges with HART read only feature.
The narrow 6 mm housing allows up to 165 units to be mounted per meter of DIN rail, without any air gap between units.
