Bistable 2-Channel DIN-Box Relay 230V AC ZAMEL PBP-05 (MPN: EXT10000254)

ZAMEL PBP-05 is a bistable 2-channel DIN-box relay designed for 230V AC mains. The unit provides two independent latching relay outputs that retain their last switched state after power interruptions, making it suitable for installations where maintained states are required. The compact DIN-rail enclosure fits electrical distribution boards and offers a practical solution for controlling lighting circuits, remote switching, and simple automation tasks in residential and light-commercial environments.

Advantages

The device combines two independent bistable relays in a single DIN-rail module, reducing panel space and simplifying wiring compared with separate relays. Bistable operation minimizes standby power consumption because coils are energized only during state change. The product is built for 230V AC supply and provides reliable switching for resistive and inductive loads commonly found in lighting and control circuits.

Suitable for

• Control of lighting circuits where the last state must be preserved after power loss
• Remote switching applications triggered by wall switches, push-buttons, or control systems
• Simple home and small commercial automation tasks requiring two independent channels
• Installation in DIN-rail electrical distribution panels

When it may not be suitable

This bistable relay is intended for low- to moderate-current switching typical of lighting and control circuits; it may not be suitable for high-power industrial loads that require dedicated contactors or motor starters. It is designed for use with 230V AC mains; applications requiring other supply voltages or direct DC switching may need a different device.

Key specifications

• Number of channels: 2 independent bistable (latching) outputs
• Operating supply voltage: 230 V AC
• Mounting: DIN-rail enclosure for distribution panels
• Intended switching applications: lighting and general control circuits
• State retention: Maintains contact state after power loss until next control pulse

How to use

Mount the module on a standard DIN-rail inside the distribution board and connect the 230V AC supply to the designated input terminals. Wire the two output channels to the controlled loads following standard electrical practice and local regulations. Operate each channel using compatible control inputs such as momentary switches or control signals; a pulse to the coil toggles the relay contact between its two stable states. Ensure that load ratings and wiring are appropriate for the type of load being switched.

What to consider before purchase

• Confirm the device is compatible with 230V AC mains in your installation
• Verify that the relay contact ratings suit the current and type of your loads (lighting, inductive loads, etc.)
• Ensure sufficient DIN-rail space in the electrical panel for the module
• Check that bistable (latching) operation aligns with your control and automation requirements

Usage recommendations

For reliable operation, use short control pulses to toggle channels and follow recommended wiring practices. When switching inductive loads, include appropriate suppression or protection devices to extend relay life. Test installation and control sequences after wiring and comply with local electrical codes during installation.
