TC Converter – Insolated

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 6.1 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.
