24V DC ON OFF Cycle Timer Relay Module (10A)
The 24V DC ON OFF Cycle Delay Relay Timer Module, commonly known as the JK11S Cycle Timer Relay Module, is a versatile electronic timer relay designed to automatically switch electrical loads ON and OFF using independently adjustable timing periods. Operating from a 24V DC power supply, this repeat cycle timer relay is ideal for automation, lighting control, motor cycling, pumps, battery charging, cooling fans, testing equipment, and countless DIY electronics projects.
The module can operate in either Once Mode or Cycle Mode. In Once Mode, the relay performs a single ON/OFF timing sequence before stopping. In Cycle Mode, the relay continuously repeats the ON and OFF timing sequence until stopped, making it ideal for applications requiring repetitive switching.

Cycle Timer Relay Applications
This electronic timer relay can be used anywhere automatic switching or repeated timing is required. Popular applications include:
- Motor start and stop control
- Pump cycling
- Cooling fan control
- LED flashing and lighting automation
- Battery charging and discharge cycles
- Industrial automation systems
- Home automation projects
- Arduino and Raspberry Pi projects
- Automatic testing equipment
- General-purpose delay timer applications
How the ON OFF Timer Relay Works
After power is applied, the module waits for a trigger from the S1 input. Once activated, the relay immediately switches ON for the configured T1 duration before switching OFF for the configured T2 duration. This ON and OFF sequence repeats continuously, allowing the module to function as a repeat cycle timer relay for continuous automation tasks.
Because both timing periods are independently adjustable, the module can be configured for a wide range of applications requiring ON delay, OFF delay or repeating timing sequences. The onboard potentiometers make adjustment quick and straightforward without requiring software or programming.
The module is suitable for switching loads up to 10A and can be wired using the Normally Open, Normally Closed and Common relay contacts to suit your application. It is commonly used as a cycle timer relay, delay relay module, timer switch and electronic timer relay in both hobby and industrial environments.
Also available in 5V DC and 12V DC versions.
