Zamel PBM-02/24V Bistable Relay 24V AC/DC

The Zamel PBM-02/24V bistable relay is a high-quality electronic impulse relay engineered for 24V AC/DC power systems. This device enables efficient control of lighting circuits or other electrical loads from several different locations by utilizing parallel-connected push buttons. Designed for seamless integration into residential and commercial automation setups, it offers reliable switching performance and energy-efficient operation within a space-saving modular housing suitable for standard DIN rail mounting.

Advantages

The primary benefit of this bistable relay is its ability to simplify complex wiring for multi-point lighting control, significantly reducing the amount of cabling required compared to traditional cross-switching systems. Its electronic design ensures silent operation and high durability, making it an excellent choice for environments where mechanical noise is undesirable. Furthermore, the compact modular design allows for easy installation in distribution boards, while the wide compatibility with 24V AC/DC power sources provides flexibility for various low-voltage automation projects.

Suitable for

• Lighting control from multiple locations in hallways or staircases
• Automation of low-voltage electrical loads in residential buildings
• Commercial facility lighting management systems
• Integration into smart home control panels requiring impulse-based switching

When it may not be suitable

This relay is specifically designed for 24V AC/DC circuits and cannot be used with standard 230V mains voltage systems. It is also not intended for high-power industrial motor control or applications requiring continuous high-current switching beyond its rated capacity.

Key specifications

• Operating voltage: 24V AC/DC
• Mounting type: DIN rail (TH35)
• Control method: Parallel-connected push buttons
• Design: Modular electronic impulse relay

How to use

The relay is installed on a standard DIN rail within an electrical distribution board. Connect the 24V power supply to the designated input terminals and wire the push buttons in parallel to the control input. Once installed, a single press of any connected button will toggle the state of the relay, switching the connected load on or off. Ensure that all wiring is performed by a qualified professional in accordance with local electrical safety regulations.

What to consider before purchase

• Verify that your power supply is strictly 24V AC/DC
• Ensure the total load current does not exceed the relay's technical limits
• Confirm that your distribution board has available space on the DIN rail

Usage recommendations

For optimal performance and longevity, ensure that the control circuit wiring is kept separate from high-voltage lines to prevent electromagnetic interference. Regularly inspect the connections during routine maintenance to ensure they remain secure.
