## Long description

The Zamel PBM-05 is a high-quality bistable relay engineered for 230V AC electrical systems, featuring a potential-free output contact for versatile circuit control. This device is specifically designed to enable the switching of lighting or other electrical loads from multiple locations by utilizing simple monostable push-buttons. Its compact modular architecture is optimized for standard DIN rail mounting, making it an efficient solution for both residential and industrial automation projects where reliable, long-term switching performance is required.
Advantages
The primary benefit of the Zamel PBM-05 is its potential-free contact, which provides complete electrical isolation between the control circuit and the load, offering greater flexibility in system design and safety. The unit is designed for seamless integration into existing electrical cabinets, occupying minimal space on a DIN rail. By supporting control from multiple parallel-connected push-buttons, it simplifies the installation of complex lighting systems in hallways, staircases, or large rooms, ensuring consistent and responsive operation without the need for complex wiring.
Suitable for
Controlling lighting systems from multiple locations
Residential automation and smart home installations
Industrial control panels and automation systems
Switching electrical loads in staircases and corridors
This relay may not be suitable for applications requiring high-frequency switching or for controlling loads that exceed the specified current and voltage ratings of the internal contact. It is also not intended for use in environments with extreme humidity or temperatures outside the manufacturer's specified operating range.
Key specifications
Supply voltage: 230V AC
Output contact type: Potential-free (NO)
Mounting type: DIN rail (TH35)
Control method: Monostable push-buttons
Design: Modular housing
To use the Zamel PBM-05, install the device onto a standard DIN rail within your distribution board. Connect the phase and neutral lines to the supply terminals and wire your monostable push-buttons in parallel to the control input. Ensure that the load is connected through the potential-free output contact according to the wiring diagram provided with the device. Once installed, a single press of any connected push-button will toggle the state of the relay, either switching the load on or off.
What to consider before purchase
Verify that your supply voltage is compatible with the 230V AC rating
Ensure your load requirements do not exceed the relay's contact capacity
Confirm that you have sufficient space on your DIN rail for a modular device
Check that your existing wiring supports the use of monostable push-buttons
For optimal performance and safety, ensure all electrical connections are tightened securely and that the installation is performed by a qualified professional in accordance with local electrical regulations.
