Velbus Four-channel relay module with potential-free outputs

the Velbus VMB4RYNO-20 4-Channel Relay Module - the heart of your smart home automation system for controlling devices. With this versatile module, take command of your living space by effortlessly managing various devices with simple controls.

Versatility at your fingertips
Whether it's illuminating your space with dynamic lighting, powering appliances, or seamlessly integrating with other smart devices like SG-ready heat pumps and alarm systems via potential-free contacts, the VMB4RYNO-20 provides the key to unlock the full potential of your automated home. It also effortlessly handles devices requiring a pulse contact, such as a garage door, for smooth and precise control.

Robust switching power
Equipped with four relays, each featuring a normal open contact, the VMB4RYNO-20 empowers you to control devices drawing up to 16 A at 230 V AC per channel, with an impressive inrush current capability of up to 80 A. Even DC power is not a problem with a rating of 12 A at 30 V DC! This makes the VMB4RYNO-20 a robust and powerful module, ensuring that your smart home operates seamlessly.

Endless customization
Customization is at your fingertips with the VMB4RYNO-20. Our user-friendly free Velbuslink software allows you to explore a range of options, enabling multiple operational modes to suit your preferences. Whether you opt for momentary control, on/off functionality, start/stop timers, staircase lighting timers, non-restartable timers, switch-off delays, switch-on delays, start timers triggered by releasing push buttons, timers with blinking effects, or 2-way timers - the choice is yours.

In addition, the VMB4RYNO-20 introduces four virtual channels that can be monitored via the module's LEDs and controlled directly using the physical buttons. Combined with logical functions (AND, OR, NOR, NAND, XOR, XNOR) in Velbuslink, this enables advanced automation scenarios tailored to your needs.

Fast wiring
Say goodbye to wiring hassles! The Velbus VMB4RYNO-20 ensures a seamless installation process in your electrical cabinet, thanks to the original WAGO push-connectors. Wiring becomes a breeze with these connectors, designed to accommodate solid wires with a cross-sectional area of 2.5 mm². Each channel of the VMB4RYNO-20 comes equipped with a bridging connector, offering added convenience to easily bridge a phase wire to each channel without any fuss.

Clear feedback at a glance
Thanks to the newly designed printed end plates, the module's status is now even easier to visualize: green LEDs clearly indicate active channels, while the heartbeat LED provides instant feedback on the overall system status, making troubleshooting more straightforward than ever.
