F143 - Temperature monitor

F143 - Temperature monitor
with high / low alarms and analog outputs

The F143 is a versatile temperature indicator featuring continuous temperature monitoring. It offers the ability to set two low and two high temperature alarm values. If desired, an ignore function can be set up to allow for an incorrect temperature for a certain period of time. Up to five outputs are available to transmit alarm conditions and actual temperature.
The display shows the actual temperature, alarm values, alarm messages and status. On-screen engineering units are easily configured from a comprehensive selection.
A wide range of options further enhance this models capabilities, including Intrinsic Safety for hazardous area applications and full Modbus communication.

Features
• Temperature monitoring: four alarm values can be set: low-low, low, high and high-high temperature alarm.
• Alarm values can be changed by the operator or they can be passcode protected.
• Analog output to transmit the actual temperature.
• Temperature and alarm values: six large 17mm (0.67") digits.
• Displays temperature, measuring unit and alarm messages simultaneously.
• Alarm ignore function allows an incorrect temperature for a certain period of time.
• Selectable on-screen engineering units:
°C - °F - K or no unit
• Up to four configurable alarm outputs.
• Displays clear alarm messages.
• Green LED backlight.
• Backup of settings in EEPROM memory.
• Operational temperature: -30°C to +80°C (-22°F to 178°F).
• Very compact design for panel mount, wall mount or field mount applications.
• Rugged aluminum or GRP field mount enclosure IP67 / NEMA4X.

Applications
For applications where continuous temperature measurement and monitoring is important. Also signal re-transmission of the actual temperature or serial communication is required.
Alternative basic models: F040, F043.
