AMX CE-REL8 Control Extender - 8 Relay
Description
AMX CE-REL8 Control Extender - 8 Relay
The AMX CE-REL8 is a compact control interface for integrating relay-based switching into networked studio automation and control systems. Its card-deck-sized footprint integrates seamlessly into live room, control room, or equipment rack installations while delivering reliable signal routing and device control for professional studio workflows.
Network Integration & Power
PoE power eliminates the need for separate power supplies, while the RJ45 Ethernet port supports network distances up to 100 meters, enabling flexible placement throughout the studio. Typical power draw of 1.9 watts (maximum 3.4 watts) keeps infrastructure demands minimal and studio power budgets tight.
Relay Switching & Protocol Support
Eight independent 1A relays rated for 24VAC or 28VDC enable control of studio lighting, monitor switching, HVAC, and other low-voltage devices critical to session management. Native support for RS-232, -422, and -485 protocols ensures compatibility with legacy and modern control systems, while the built-in web interface and open control API integrate seamlessly with third-party studio control platforms and DAW automation workflows.

Frequently Asked Questions
What devices can the CE-REL8 control?
The eight 1A relays are rated for 24VAC or 28VDC and can switch lighting, HVAC systems, and other low-voltage devices commonly found in commercial and studio installations. Each relay is independent, allowing simultaneous control of multiple devices across your networked system.
Do I need a separate power supply?
No. The CE-REL8 is powered over Ethernet (PoE), so power and control signals travel through the same RJ45 connection, with typical draw of 1.9 watts and maximum of 3.4 watts. Ethernet runs can reach up to 100 meters from your control source.
What control protocols does it support?
The CE-REL8 supports RS-232, RS-422, and RS-485, making it compatible with legacy and modern AV control systems. It also includes a built-in web interface and open API for integration with third-party platforms and custom automation software.
How difficult is it to integrate into an existing system?
Two eight-pin terminal block connectors simplify wiring, and the built-in web interface allows straightforward configuration without specialized tools. The open API and multi-protocol support mean you can connect it to most networked control systems with minimal custom programming.
Is this suitable for portable or live-sound applications?
No. The CE-REL8 is designed for fixed commercial and studio installations where networked integration and permanent mounting are required; it is not intended for portable live-sound or traveling rigs.
