Use this Zener barrier from Eaton MTL with a temperature sensor in a hazardous location. It converts electrical signals to current levels that are safe for a connected instrumentation device. For versatility, the unit is compatible with both thermocouples and RTDs (resistance temperature detectors). An integrated alarm output notifies you if the preset temperature limits have been reached, allowing you to act quickly. Thanks to its maximum current consumption of 50mA at 24V, this device is energy-efficient. You'll commonly find it used in industrial automation applications.


• LED indicators display operating status for ease of monitoring
• Rapid response time of 500ms for fast operation
• Low power dissipation of 1.2W ensures minimal energy loss
• Designed for DIN rail mounting for quick and simple installation
• Broad operating temperature range between -20°C and +65°C for use in demanding environments


How do I configure this Zener barrier?

You can configure this device by connecting it to your computer and setting up the compatible MTL PCS45 software with a PCL45USB serial interface. This lets you adjust the parameters for the thermometers and RTDs and set the alarm output to low-process or high-process.
