PoE Control Expander with Serial, IR, Relay & Digital I/O New

Every control system hits a wall when the device it needs to manage is across the room — or across the building — from the processor. The KanexPro CR-EXPAND1 puts serial, IR, relay, and digital I/O wherever you need them, powered and connected by a single Ethernet cable. Mount it behind a display, above a projector, or in a remote closet — one PoE drop gives you RS-232/RS-485 for device control, IR output for legacy equipment, two relays for screens and lighting, and a digital I/O port for sensors or contact closures.

Unlike competitors that sell separate boxes for serial, IR, and relay expansion, the CR-EXPAND1 combines all four port types in one compact device. A built-in web server provides browser-based configuration without special software, and open API commands over TCP/UDP mean it works with any IP-based control system. Dual power input (DC 12-24V or PoE) keeps deployment flexible.

• 1x RS-232/RS-485 bidirectional serial port for device control
• 1x IR output port with 20KHz-60KHz carrier for legacy devices
• 2x low-voltage relays for screens, lighting, access control, and curtains
• 1x digital I/O port for sensor or dry contact monitoring
• 1x 100M Ethernet with TCP/UDP communication and PoE power input
• Built-in web server for browser-based configuration
• Built-in API commands for integration with any IP-based control system
• Dual power supply: DC 12-24V or PoE
• Front panel status LEDs: Power, TX, RX, I/O, IR, Relay 1, Relay 2
