SRD-24VDC-SL-C Relay 24V DC Coil, 10A, SPDT, 220VAC, 5 Pin
Product Overview
The SRD-24VDC-SL-C from Pro Tronix is designed for stability and reliability in environments where 24V DC is the primary control voltage. Unlike 5V or 12V relays, the 24V version is widely utilized in industrial automation, where it serves as a robust bridge between PLC (Programmable Logic Controller) outputs and high-power AC/DC loads.
With its SPDT (Single Pole Double Throw) configuration, it provides a versatile switching solution, offering both Normally Open (NO) and Normally Closed (NC) contacts. Its compact “Sugar Cube” design allows for high-density mounting on PCBs, making it a favorite for manufacturing custom industrial interface boards and control systems.

Key Features
-
Industrial Voltage Compatible: Designed specifically for 24V systems, which are the standard in factory automation and industrial machinery.
-
Low Current Draw: The high resistance of the 24V coil ensures minimal current consumption while the relay is energized.
-
Compact Powerhouse: Switches up to 10A in a miniature footprint, saving valuable space in control cabinets.
-
Versatile Logic: Features one set of change-over contacts to handle diverse switching requirements (Normally Open or Normally Closed).
Common Applications
-
PLC Interfacing: Using low-current PLC outputs to toggle high-power motors, solenoids, or heaters.
-
Truck & Heavy Machinery: Controlling auxiliary lighting, hydraulics, or alarm systems in 24V vehicle electrical systems.
-
Industrial Control Panels: Acting as an intermediate relay for signal isolation and power amplification.
-
Solar Energy Systems: Toggling loads in 24V battery bank configurations common in off-grid solar setups.
