Time Relay FF PCA-512 24V 1P 10A 0.1s–576h for AC/DC control circuits

Electromechanical time relay FF PCA-512 24V is a compact timing device with a single pole (1P) contact rated for 10 A and an adjustable timing range from 0.1 seconds to 576 hours. Designed for 24 V AC/DC control supply, the relay provides reliable timed switching for a variety of control circuits in industrial and building automation systems, including lighting, motor control and delay functions.

Advantages

The relay offers wide timing flexibility, covering very short intervals up to long multi-day delays, making it suitable for diverse control tasks. Its electromechanical design ensures clear switching feedback and robust contact performance at currents up to 10 A. Compatibility with both 24 V AC and DC control supplies simplifies integration into existing installations that use this common control voltage. The compact form factor and standardized mounting enable straightforward installation in control panels and on DIN rails.

Suitable for

• Lighting control and timed illumination sequences
• Motor start/stop delays and sequencing
• Pump and valve delay circuits in HVAC and water systems
• Industrial automation where long or short delays are required
• Safety interlocks and timed reset functions

Key specifications

• Control voltage: 24 V AC/DC
• Contact configuration: single pole (1P)
• Contact rating: 10 A
• Timing range: 0.1 seconds to 576 hours (adjustable)
• Timing type: electromechanical
• Typical mounting: panel/DIN rail compatible form factor

How to use

Install the time relay in the control panel or on a DIN rail according to local wiring and safety regulations. Connect the 24 V AC or DC control supply to the designated coil terminals and wire the load through the single pole contact rated for 10 A. Adjust the desired timing interval using the front or top-mounted adjustment control, observing the specified range from 0.1 s to 576 h. Test the timing function under no-load conditions first, then verify correct operation with the intended load. Ensure correct polarity when using DC supply and secure all terminal connections.

Usage recommendations

For reliable long-term operation, avoid switching inductive loads near the maximum contact rating without appropriate suppression (such as snubbers or RC networks). Regularly inspect contacts in demanding environments and follow manufacturer guidelines for maintenance intervals. Use the relay within the specified voltage and temperature ranges and ensure proper protective devices are in place for motor or pump applications.
