Tasteninterface (55 mm Schalterdose)

Tasteninterface mit Cresnet-Busanschluss für bis zu 8 potentialfreie externe Tasten. Zur Rückmeldung stehen 8 umschaltbare Ausgänge zum Betrieb von LEDs oder Anzeigelampen oder auch zum Schalten von externen Relais zur Verfügung. Input: 0-24VDC, 1 bis 3,7 mA. Output: 24VDC, 100 mA je Out, max 500 mA pro Modul. Einbau in 55 mm UP-Dose. Interface auch passend für unsere NIKO Schalterserie.

The C2N-UNI8IO is a compact interface which allows a third-party keypad to be connected directly to the Cresnet® control network. Its low-profile design makes the C2N-UNI8IO excellent for installation directly inside a 55mm European electrical box or other suitable enclosure. Supporting up to 8 buttons and indicators, the universal keypad interface can be used in a variety of applications including homes and offices where custom styling is of the most importance, or museums and courtrooms where simple user interfaces are required.

Because it supports contact closure inputs, the C2N-UNI8IO can transform virtually any button or switch into a Cresnet device. The simple low-voltage, 4-wire bus makes Cresnet the smart choice in wiring infrastructure, allowing daisy chaining of devices for present or future needs. Simply add door sensors to systems providing indication of entry or exit, or take a doorbell to the next level by triggering the audio system when "rung."

More than just an input interface, 8 low-voltage outputs are capable of driving LEDs, relay coils, or lamps. Visual feedback is natively supported with the C2N-UNI8IO because it's capable of delivering various light intensities and blinking patterns to LEDs. Just as Crestron keypads indicate which source is selected or what lighting scene has been chosen, the universal keypad interface lets any keypad follow suit.

Key Features


  • Transforms a third-party keypad into a Cresnet® device
  • Low-profile design fits in 55mm European electrical box

  • Drives up to 8 LEDs for feedback


  1. Actual load capability dependent upon the amount of available Cresnet power in the system.

  NET (1) 4-pin 3.5mm detachable terminal block; Cresnet slave port, connects to Cresnet control network
  INPUT (1) 10-pin 0.1” IDC connector, includes (10) single conductor 22 AWG 3” flying leads
Inputs comprised of (2) GND references and (8) digital inputs (referenced to GND);
  OUTPUT (1) 10-pin 0.1” IDC connector, includes (10) single conductor 22 AWG 3” flying leads Outputs comprised of (1) 24VDC, (1) 5VDC, and (8) digital outputs (referenced to GND);
Note: 24V connector is a Cresnet power pass-thru
  Digital Inputs (8) Inputs rated for 0-24 Volts DC, includes 10K ohm pull-up to 5VDC
Logic Low Threshold: ≤1 Volt Logic High Threshold: ≥3.7 Volts
  Digital Outputs (8) Open drain outputs rated for 100mA @ 24VDC, 500mA max (combined for all 8 outputs), when not in "current limit" mode
Maximum Power Load: 1A @ 24VDC[1] and 40mA @ 5VDC
Controls & Indicators
  SETUP (1) Red LED and (1) miniature pushbutton, used for touch-settable ID (TSID)
