Description
Johnson Controls DT13E-24 DC to DC Isolator Overview
The Johnson Controls DT13E-24 is a DC to DC Isolator designed for 24 Vac-powered building automation and HVAC control systems. This isolator provides reliable electrical isolation between DC control signal circuits, helping to eliminate ground loops, reduce noise interference, and protect sensitive control equipment from voltage transients and signal distortion.
Key Features
- DC to DC signal isolation for building automation and HVAC control applications
- 24 Vac operating power supply
- Eliminates ground loops between interconnected control devices
- Protects downstream controllers and sensors from voltage transients
- Reduces electrical noise and signal interference on DC control loops
- Compact design suitable for panel or DIN rail mounting in control enclosures
- Compatible with Johnson Controls building automation system (BAS) architectures
Application
The DT13E-24 is ideal for use in commercial HVAC and building automation installations where DC analog signals — such as 0–10 Vdc or 4–20 mA control signals — must be transmitted between devices with different ground references. It is commonly used to interface sensors, actuators, and controllers in Johnson Controls BAS environments, ensuring signal integrity and system reliability.
Why Choose the Johnson Controls DT13E-24?
- Trusted Johnson Controls quality for commercial building automation
- Simplifies troubleshooting by eliminating ground loop-induced signal errors
- Helps maintain accurate control in variable air volume (VAV), AHU, and other HVAC applications
- Supports long cable runs where signal degradation is a concern
