* Excellent EMC perforemance and 50/60 Hz noise suppression
* Selectable < 30 ms / 300 ms response time
* Pre-calibrated temperature ranges are selectable via DIP-switches
Application
* The 3112 temperature converter measures a standard 2-, 3- or 4-wire Pt100 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 3112 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.
* Excellent conversion accuracy in all available ranges, better than 0.05% of span.
* Meeting the NAMUR NE21 recommendations, the 3112 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.
