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.
