DC/DC Converter TracoPower TMR 1-1215, 1 W, 24 V output, 42 mA, SIL-6

The TracoPower TMR 1-1215 is a compact 1 W DC/DC converter that provides a regulated 24 V output at up to 42 mA. Engineered for applications requiring galvanic isolation and consistent low-power supply, this module meets SIL-6 safety level requirements and is intended for industrial control, instrumentation, and embedded systems where isolated, stable power for signal-level and low-current loads is needed.

Advantages

The module offers a small footprint and low power dissipation while delivering a regulated 24 V output suitable for sensors, relays, and logic circuits. Built to provide galvanic isolation, it reduces interference between input and output domains and enhances functional safety in systems designed to SIL-6 standards. The converter's predictable behaviour under light loads and its compact design simplify integration into space-constrained control panels and embedded boards.

Suitable for

• Isolated power for instrumentation and measurement equipment
• Low-current signal circuits, sensors and transmitters
• Embedded systems and control modules with limited space
• Functional safety applications requiring SIL-6 compliant isolation
• Industrial automation interfaces and low-power logic supplies

When it may not be suitable

This DC/DC converter is not suitable for high-current or high-power applications due to its 1 W power rating and 42 mA maximum output current. It is also not intended for use where unregulated or higher-voltage outputs are required, or for loads that exhibit large inrush currents that exceed the converter's rating.

Key specifications

• Output power: 1 W
• Nominal output voltage: 24 V
• Maximum output current: 42 mA
• Isolation: galvanic isolation suitable for functional safety applications
• Intended use: low-power, signal-level and instrumentation loads

How to use

Install the converter according to the manufacturer's mechanical and electrical guidelines, ensuring correct input voltage polarity and secure mounting in a well-ventilated enclosure. Connect the input supply within the specified range and verify the output with a multimeter before connecting sensitive loads. When integrating into safety-related circuits, follow system-level functional safety requirements and perform appropriate validation and testing after installation.

What to consider before purchase

• Confirm the required output voltage and that 24 V at 42 mA meets your load needs
• Ensure the 1 W power rating is sufficient for peak and continuous consumption
• Verify isolation and safety level are appropriate for your application
• Check mechanical dimensions and mounting compatibility with your enclosure

Usage recommendations

Use this converter for low-current, isolated supplies where functional safety and compact size are priorities. Avoid operating near the maximum rated current for extended periods and include appropriate filtering or decoupling at the output when powering sensitive analog or digital circuits.
