Multifunction zero-crossing time relay 230V AC PCM-34 EXT10000308

Multifunctional zero-crossing time relay – precision and durability

The PCM-34 time relay is a universal device designed for a wide range of applications in building automation, industrial automation, and smart homes. Equipped with 10 programmable operating modes, it offers flexibility and adaptation to specific installation needs. A key feature is the zero-voltage and current switching technology, which significantly extends the lifespan of both the relay and the connected receivers.

Functionality and application

PCM-34 allows for time-based control of various loads, from lighting to ventilation and heating systems. The ability to trigger operating modes with an external signal or a change in the supply voltage increases its versatility. This relay is ideal for tasks requiring precise time measurement, delayed switching, or pulse generation. Thanks to its compact size (2 module width) and standard DIN rail mounting, integration with an existing installation is simple and quick.

Advantages for professionals and end-users

• Multifunctionality: One relay replaces many traditional solutions, reducing costs and simplifying installation.
• Zero-crossing switching: Reduces contact wear and extends the life of connected devices – especially those sensitive to voltage spikes, such as LED lighting or switch-mode power supplies. This translates to a lower risk of failure and less frequent component replacement.
• High switching capacity: Rated current of 16A at 230V AC allows control of even powerful receivers (up to 3000W for incandescent bulbs).
• Triggering flexibility: The ability to choose triggering with an external signal or a change in the supply voltage adapts the relay's operation to specific application requirements.
• Compact dimensions: Saves space in the distribution board thanks to a width of only 2 modules.
• Easy installation: Standard DIN rail mounting simplifies installation and servicing.

PCM-34 is a solid solution for installers looking for a reliable and versatile time control device, as well as for end-users who value comfort, safety, and energy efficiency. The device is manufactured by ZAMEL Sp. z o.o., a Polish manufacturer with an established position in the electrical engineering market.
