BSS BLU-GPX Networked General Purpose I/O Expander

BSS BLU-GPX General Purpose I/O Expander Overview
The BSS BLU-GPX General Purpose I/O Expander is a versatile network-controlled GPIO expander designed to enhance the functionality of your Soundweb London system. It provides an efficient way to add control inputs, logic outputs, and relay outputs to systems that require extra analog control and interfacing capabilities. With its robust feature set and EN 54-16 compliance for life safety applications, the BLU-GPX is ideal for commercial, industrial, and safety-critical environments. This device is an essential addition to any networked audio system that needs increased control and interaction with external equipment.

Efficient Control and Logic Outputs for Seamless Integration
The BLU-GPX features 36 control inputs and 23 logic outputs, enabling flexible and reliable integration with a variety of external devices. The control inputs can be connected to contact closures for binary control, resistor ladders for multi-state control, or potentiometers for continuous parameter control, offering a wide range of possibilities for user interaction with the system. The logic outputs are ideal for interfacing with voltage-controlled electrical components such as LEDs and relays, providing a straightforward method for managing signals and triggering actions within the system.

Integrated Relay Outputs for Direct Control
With 8 integrated relay outputs, the BLU-GPX reduces the need for external relays, simplifying the installation and reducing costs. Each relay output features Normally Open (NO) and Normally Closed (NC) terminals, which are controlled by HiQnet parameters. This enables the relay outputs to interface directly with resistance-controlled electrical components and circuits, making it ideal for controlling various devices such as lighting, security systems, or other automated equipment. The inclusion of these relay outputs makes the BLU-GPX a more comprehensive and cost-effective solution for a wide range of applications.

Simplified Wiring with Commons and Reference Connections
The BLU-GPX is designed to simplify wiring by including 47 common (ground) connections and 12 reference connections for 3-wire mode operation. These additional connections reduce the need for spanning across terminal block connectors, providing a more organized and easier-to-manage setup. The device also allows for 2-wire or 3-wire mode specification per input bank, giving you flexibility in how you integrate your control and logic systems. This design minimizes complexity and ensures a cleaner, more efficient installation.

Intuitive Configuration with HiQnet Audio Architect
The BLU-GPX is fully configurable through HiQnet Audio Architect, providing a rich array of logic objects and a drag-and-drop method for easy setup. Whether you are designing a simple control system or a complex audio network, HiQnet offers an intuitive platform to manage your configurations. The device is controlled, monitored, and powered through the two PoE-enabled Ethernet ports, and it can also be controlled via the RS-232 serial port. The 12VDC secondary power connector ensures reliable power backup for uninterrupted operation.

Front Panel Indicators for Monitoring and Alerts
The BLU-GPX offers enhanced monitoring and feedback via its front panel. It features 48 software-programmable multi-color LEDs (red, green, yellow) that can be customized to display various system statuses or alerts. The front panel also includes a monochromatic LCD screen with 80x16 resolution, providing text-based visual indications of user-defined events. Additionally, a 4 kHz piezo buzzer offers audible alerts for critical notifications, ensuring that users are promptly informed of important system changes or issues.
