The Soundweb London BLU - GPX is an outstanding network - controlled GPIO expander. It's a cost - effective solution for adding control inputs, logic outputs, and relays to systems that need extra analog control or interfacing capabilities. This device features a rich set of logic objects, just like other Soundweb London products. It comes with two PoE - enabled Ethernet ports for communication, primary power, and redundant comms, a 12VDC power connector for backup, an RS - 232 port for serial device compatibility, user - configurable front - panel LEDs, an LCD, and a 4kHz piezo buzzer for audible alerts. The BLU - GPX has 36 control inputs that can be connected to various components for different parameter controls. It also offers a bi - directional locate function for easy device identification. Key features include 36 Control Inputs (GPI), 23 Logic Outputs (GPO), 8 NC/NO Relay Outputs, 47 Commons for simple wiring, 12 Reference Connections for 3 - Wire Mode, and more. Technical specs cover control ports, input and output voltages, impedance, relay details, power requirements, and dimensions.
Using the Soundweb London BLU - GPX is straightforward. First, connect it to your system using the Ethernet ports or the 12VDC power connector for backup. The control inputs can be linked to contact closures, resistor ladders, or potentiometers as needed. The logic outputs and relay outputs can be configured to perform specific tasks. When setting up, make sure the input voltage and impedance are within the specified range (0 to 4.5v for control input voltage). For the Ethernet connection, use a Category 5 cable with a maximum length of 100m/300ft. Keep the device in an environment with an operating temperature between 5(41) and 35(95) degrees C(degrees F). For maintenance, check the front - panel LEDs regularly to monitor power supply, network link, and data activity. If there are any issues, refer to the technical specifications and use the bi - directional locate function to identify the device easily. Avoid exposing the device to high - voltage or extreme temperature conditions to ensure its long - term performance.
