Time relay 24V AC/DC Type: PCM-03/24V EXT10000079

Time relay for automation and control

The PCM-03/24V time relay is a reliable element of building and industrial automation, designed for cyclic switching of circuits. It enables precise time control over a wide range – from 0.1 seconds to 10 days, making it an ideal solution for automating lighting, ventilation, irrigation systems or pump control. LED indicators facilitate monitoring and diagnostics.

Functionality and application

The device is powered by 24V AC/DC and offers functions for both delayed switching on and off. Additional modes for constant switching on (ON) or off (OFF) increase its versatility. The relay is used in building installations, industrial control systems and anywhere where precise time control of devices is required. Thanks to the wide range of time settings, it will work in both short-term and long-term applications.

Construction and mounting

The PCM-03/24V relay is characterized by a compact design – the housing is one module wide (17.5 mm), allowing for easy mounting on a standard TH-35 rail. It has one changeover contact (1NO/NC) with a maximum load of 16A at 250V AC and a power of up to 4000 VA. LED indicators inform about the supply voltage, relay status and time measurement. The device is designed to operate at temperatures from -20°C to +45°C and has a protection class of IP20 – which means it is intended for use indoors.

Additional information:

• Wide time setting range: from 0.1 s to 10 days – allows adaptation to specific application needs.
• Universal power supply: possibility of powering with both AC and DC voltage (24V).
• High contact load capacity: allows control of most typical receivers.
• Additional functions: constant on or off modes increase application flexibility.
• Compact dimensions: facilitate mounting in limited space.
• LED indication: provides quick information about the device status.
• Mounting on TH-35 rail: standard mounting method facilitates integration with existing installations.
