The Interra ITR212-0005 is a 12-channel Ethernet I/O module for residential and hotel automation over IP. Like its 8-channel sister, it is mains-powered (100–250 V AC), needs no separate PSU, and talks to Interra touch panels and HomeServer over Ethernet. Channel mapping, logic and scenarios are set with the EIO Configuration software; the LCD and Manual Panel provide on-device and software feedback.

Per the Interra family datasheet, ITR212-0005 provides 12 binary inputs, 12 virtual inputs and 12 binary outputs with 16 A contacts (inrush up to 100 A). Output modes include ON/OFF, toggle and timed control; shutter/blind configurations use 24 V (up to 4 outputs) or 230 V AC (up to 2 outputs). Up to 10 scenarios, cross-channel logic and last-state memory after power loss match the ITR208 feature set at higher density.

Key Features — 12-Channel Ethernet I/O

• 12 / 12 / 12 I/O: Higher channel count on the same 9-module DIN form factor as ITR208-0005.
• Ethernet + LCD: IP integration with Interra panels / HomeServer; local status and menu.
• 16 A relays: Lighting and loads; verify capacitive inrush before connecting.
• Shutter modes: 24 V or 230 V AC shutter/blind wiring options per Interra docs.
• Scenarios & logic: Up to 10 scenarios; logic across inputs, outputs and virtual inputs.
• Mains powered: 100–250 V AC @ 50 Hz; typ. 0.9 W; IP20; RAL 7035.

• Larger rooms / suites: More conventional inputs and relay channels than the 8-fold module while keeping Ethernet panel integration.
• 8-channel sister: ITR208-0005 when 8 channels suffice.
• KNX-native inputs: ITR112-0000 for dry contacts on KNX TP.
• Panels: iX3 / iX2 for Interra Ethernet room UX.

Choosing and Commissioning

Choose ITR212-0005 for 12-channel Ethernet I/O; use ITR208-0005 for 8 channels. Commission with EIO software over IP; name channels clearly and back up configurations. Install on TH 35 DIN rail in dry locations with proper 230 V insulation. Ratings and wiring are in the Datasheet / Product Manual under Downloads.
