Relay module Audac ARU208 — Audac ARU208 relay control module

Audac ARU208 is a relay control module engineered for switching and managing electrical circuits within audio/AV installations and building automation systems. The module supplies multiple relay-operated contacts that enable remote or automated control of peripheral equipment such as amplifiers, projectors, lighting fixtures, and access control devices. Designed for integration with Audac control ecosystems and compatible third-party controllers, this relay module supports reliable, low-latency switching for routine and scheduled control tasks.

Advantages

The Audac ARU208 offers compact, DIN-rail or panel-mountable form factor suitable for system cabinets and distribution racks. Its relay contacts deliver galvanic isolation between control input and switched circuits, improving safety and reducing interference risk. The module provides deterministic switching behavior and straightforward wiring terminals for quick installation and maintenance. Compatibility with Audac control protocols and common third-party controllers simplifies integration into existing audio/AV or building automation setups.

Suitable for

• Switching amplifier standby or mute circuits in multiroom audio systems
• Controlling projector power and screen motors in conference rooms
• Managing lighting zones for presentation or event spaces
• Integrating with access systems for door release or relays
• Triggering external devices in automated building-control scenarios

Key specifications

• Relay-operated switching contacts for controlling external electrical loads
• Multiple channels to control several devices independently
• Galvanic isolation between control signals and switched circuits
• Compact module size suitable for mounting in equipment racks or control cabinets
• Standard screw-terminal connections for reliable wiring
• Designed for integration with Audac control systems and compatible third-party controllers

How to use

Install the Audac ARU208 in a suitable equipment cabinet or mounting rail and connect the control lines from the main controller according to the system wiring diagram. Wire the output relay contacts to the power or control inputs of the devices to be switched, observing correct polarity and voltage limits of the connected equipment. Configure the controlling processor or Audac interface to assign commands to the module channels, then test each relay operation to verify correct response and safe operation. Follow electrical safety practices and local regulations during installation.

Usage recommendations

Use the ARU208 for low-voltage control and switching tasks; verify load ratings of connected devices and avoid exceeding contact current/voltage limits. For critical applications, pair the module with properly rated contactors or protection devices. Keep wiring short and well-organized to reduce noise and ensure reliable control signal transmission.
