The Interra ITR112-0000 is a 12-channel KNX binary / analog input module (family coding ITR112-000X) for connecting conventional push-buttons, switches and floating contacts to the KNX bus. The Interra KNX certificate for this product lists order number ITR112-0000 — 10 Binary, 2 Binary/Analog Input with 2 Thermostat. Dry-contact inputs on the rear connector feed switch, dimming, shutter, scene, RGB/RGBW, sequence and thermostat functions configured in ETS5 or higher.

In the ITR112-000X family, the trailing digit selects how many channels are binary/analog (temperature-probe capable): X=2 / 4 / 6. This SKU corresponds to the 2 binary/analog + thermostat coding documented on Interra’s product page. Each analog input can drive thermostat channels; Interra lists a compatible NTC probe (HM001718, 10 kΩ, 1.5 m) ordered separately. Front push-buttons allow manual simulation of each input during commissioning without wiring the field contacts.

Key Features — 12-Channel Binary / Analog Input

• 12 dry-contact inputs: Interface conventional buttons/switches and binary signals to KNX.
• 2 binary/analog channels: Temperature-probe capable inputs for thermostat applications (ITR112-0000 / 000X coding).
• Rich ETS functions: Switch, switch/dimming, shutter, value/forced, scene, RGB/RGBW, mode selection, command sequence, counter, thermostat.
• Manual operation: Per-input front buttons for simulation during commissioning.
• Compact MDRC: 90 × 36 × 71 mm; bus-powered 5 mA; IP20; KNX certified; S-Mode.
• Cable limits: Max. 30 m at 1.5 mm²; cross-section 0.25…1.5 mm² (Interra datasheet).

• Plant feedback: Window/door contacts and binary status into visualisation.
• Local comfort: Thermostat channels via analog inputs + optional NTC probe (ordered separately).
• Related on Smartanix: Sister thermostat-heavy codings such as ITR112-0002 where listed; actuators e.g. combo switch ranges; bus supply ITR900 640 mA.

Choosing and Commissioning

Confirm whether you need the 2 / 4 / 6 binary-analog (thermostat) coding before ordering. Commission with the Interra ETS application for ITR112-0000 (S-Mode; .knxprod under Downloads). Order temperature probes separately if analog thermostat inputs are used. Full ratings, connector map and function lists are in the Datasheet and Product Manual under Downloads.
