{"product_id":"crestron-c2n-uni8io","title":"Crestron C2N-UNI8IO – Universal Keypad Interface","description":"\u003ch2\u003eProduct Overview\u003c\/h2\u003e\u003cp\u003eThe Crestron C2N-UNI8IO is a compact universal keypad interface that connects virtually any third-party keypad or button panel to the Cresnet control network. With support for 8 digital inputs and 8 digital outputs, it gives AV integrators a flexible solution for custom-styled control interfaces in residential, commercial, and institutional installations.\u003c\/p\u003e\u003ch2\u003eProduct Description\u003c\/h2\u003e\u003cp\u003eThe C2N-UNI8IO allows a non-Crestron keypad — or any device with dry-contact outputs — to function as a native Cresnet device. Its ultra-slim profile fits directly inside a standard 55 mm European electrical box, making it suitable for architecturally demanding installations where aesthetics dictate the choice of control surface. Eight digital inputs accept 0–24V DC contact closures, while eight open-drain outputs rated at 100 mA each can drive LEDs, relay coils, or small lamps at up to 24V DC. An integrated DIP switch enables per-output current limiting to 5 mA for direct LED operation without external resistors. Power is derived from the Cresnet bus at 0.5 W, so no separate power supply is needed at the device.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e8 digital inputs and 8 digital outputs on a single Cresnet device\u003c\/li\u003e\n\u003cli\u003eLow-profile design fits inside a 55 mm European electrical box\u003c\/li\u003e\n\u003cli\u003eContact closure inputs accept 0–24V DC signals with 10K ohm pull-ups to 5V\u003c\/li\u003e\n\u003cli\u003eOpen-drain outputs rated 100 mA at 24V DC; 500 mA combined maximum\u003c\/li\u003e\n\u003cli\u003eBuilt-in 8-position DIP switch for per-output current limiting (5 mA at 5V for LEDs)\u003c\/li\u003e\n\u003cli\u003ePowered directly from Cresnet — no separate supply required (0.5 W draw)\u003c\/li\u003e\n\u003cli\u003eTouch-settable device ID via on-board SETUP button and LED\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTypical Applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eIntegrating designer third-party keypads into Cresnet control systems\u003c\/li\u003e\n\u003cli\u003eMuseum or courtroom installations requiring simple, custom-styled interfaces\u003c\/li\u003e\n\u003cli\u003eAdding door\/gate contact sensors to building automation programs\u003c\/li\u003e\n\u003cli\u003eProviding LED feedback on any standard button panel without a dedicated Crestron keypad\u003c\/li\u003e\n\u003cli\u003eConverting doorbells or standard switches into Cresnet event triggers\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eDigital Inputs: 8, rated 0–24V DC; 10K ohm pull-up to 5V; Logic Low ≤1V, Logic High ≥3.7V\u003c\/li\u003e\n\u003cli\u003eDigital Outputs: 8 open-drain; 100 mA at 24V DC each; 500 mA combined maximum\u003c\/li\u003e\n\u003cli\u003eMaximum Power Load: 1A at 24V DC (pass-thru) and 40 mA at 5V DC\u003c\/li\u003e\n\u003cli\u003eCresnet Power: 0.5 W (0.02 A at 24V DC)\u003c\/li\u003e\n\u003cli\u003eConnectors: NET — (1) 4-pin 3.5 mm terminal block (Cresnet slave); INPUT — (1) 10-pin 0.1-in IDC with flying leads; OUTPUT — (1) 10-pin 0.1-in IDC with flying leads\u003c\/li\u003e\n\u003cli\u003eDimensions: 52.3 mm H x 51.9 mm W x 17.3 mm D (2.06 x 2.05 x 0.68 in)\u003c\/li\u003e\n\u003cli\u003eWeight: 23.1 g (0.815 oz)\u003c\/li\u003e\n\u003cli\u003eOperating Temperature: 0° to 40°C (32° to 104°F)\u003c\/li\u003e\n\u003cli\u003eOperating Humidity: 10% to 95% RH non-condensing\u003c\/li\u003e\n\u003cli\u003eSKU: C2N-UNI8IO\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFAQs\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eCan the C2N-UNI8IO control any keypad brand?\u003c\/strong\u003e\u003cbr\u003eYes.
