Johnson Controls DT13E-24 Isolator

The Johnson Controls DT13E-24 is a professional-grade DC to DC isolator designed for high-performance HVAC control signal isolation. Operating on a 24 Vac power supply, this model serves as the direct updated version for the legacy DT13-24, engineered to eliminate ground loops and minimize common-mode signal interference in sensitive building automation systems. This transmitter accepts current or voltage inputs and provides a linearly transferred output, ensuring signal integrity between field devices and controllers like BAS or HVAC controllers.

This analog signal isolator is vital for technicians managing electrically noisy environments where crosstalk or data corruption is a risk. With 1000V isolation capability and jumper-selectable ranges (including 4-20 mA and 0-10 VDC), the DT13E-24 offers the flexibility required for industrial control panels, air handling units, and boilers. Its snap-track mounting simplifies installation, while the precision 0.5% linearity maintains accurate process monitoring across variable speed drives and data loggers. This rugged electronic component is built to withstand the demands of professional mechanical rooms while protecting expensive control assets.

Key Benefits

• Signal Integrity: High-level electrical isolation prevents ground loop interference and protects sensitive low voltage inputs.
• Backwards Compatibility: Seamlessly replaces the older Johnson Controls DT13-24 without requiring major control sequence adjustments.
• Versatile Configuration: Jumper-selectable input and output ranges allow for rapid field adaptation between multiple signal types.
• Reliable Performance: Enhanced noise rejection ensures consistent data transmission in commercial HVAC applications.

Common Questions

• How do I configure the signal ranges? The DT13E-24 features internal jumpers for easy selection of common industrial signals such as 0-10V or 4-20mA.
• Can this unit replace a DT13-24? Yes, this is the official updated model designed to provide identical functionality with improved electrical stability.
• Is the mounting hardware included? The unit includes standard snap-track for quick installation within standard automated control enclosures.
