Zamel PBM-03/24V Bistable Relay with Timer 24V AC/DC

The Zamel PBM-03/24V is a high-quality bistable relay designed for efficient control of lighting and electrical loads in 24V AC/DC systems. This device enables the switching of circuits using momentary push-buttons, providing a modern alternative to traditional mechanical switches. With its integrated timer function, the relay allows for automatic load deactivation after a pre-set time, enhancing energy efficiency and convenience in various electrical installations.

Advantages

The primary benefit of this bistable relay is its versatility in managing electrical circuits from multiple locations using simple momentary switches. The built-in timer provides precise control over how long a load remains active, which is particularly useful for managing lighting in areas where manual shut-off is often forgotten. Its compact design ensures easy integration into standard electrical distribution boards, while the robust construction guarantees reliable performance in both residential and industrial environments.

Suitable for

• Stairwell and corridor lighting control
• Automated ventilation systems
• Industrial process automation
• Residential smart home electrical setups
• Energy-saving lighting management

When it may not be suitable

This device is specifically designed for 24V AC/DC systems and cannot be used directly with standard 230V mains voltage without appropriate transformers. It is also not intended for applications requiring complex logic programming or high-frequency switching beyond its rated capacity.

Key specifications

• Supply voltage: 24V AC/DC
• Control type: Bistable with timer function
• Input: Momentary push-button compatible
• Mounting: DIN rail (TH35)
• Operating mode: Adjustable time delay

How to use

The relay is designed for installation on a standard TH35 DIN rail within an electrical distribution cabinet. Once mounted, connect the 24V power supply to the designated terminals and wire the momentary push-buttons to the control input. The timer duration can be adjusted using the integrated control dial on the front of the device. Ensure all wiring is performed by a qualified professional in accordance with local electrical safety regulations.

What to consider before purchase

• Verify that your system operates on 24V AC/DC voltage
• Ensure the load current does not exceed the relay's maximum switching capacity
• Check available space on your DIN rail for installation
• Confirm compatibility with your existing momentary switch configuration

Usage recommendations

For optimal performance and longevity, ensure the relay is installed in a dry, dust-free environment within an electrical enclosure. Regularly inspect the connections to ensure they remain tight and free from oxidation.
