The Interra ITR208-0005 is an 8-channel Ethernet I/O module for residential and hotel automation over IP — not a KNX TP actuator. It is mains-powered (100–250 V AC), needs no separate PSU, and communicates with Interra touch panels and Interra HomeServer via Ethernet. Inputs, outputs and virtual channels are configured with Interra’s EIO Configuration software; status can be monitored on the device LCD and in the software Manual Panel.

Per the shared Interra datasheet for ITR208-0005 / ITR212-0005, this coding provides 8 binary inputs, 8 virtual inputs and 8 binary outputs with 16 A contacts (inrush up to 100 A). Outputs support ON/OFF, toggle and time-dependent control; shutter/blind modes use groups of outputs (24 V with up to 4 outputs, 230 V AC with up to 2). Up to 10 scenarios and logic between inputs/outputs/virtual inputs are available, with last-state memory after power failure.

Key Features — 8-Channel Ethernet I/O

• 8 / 8 / 8 I/O: Binary inputs, virtual inputs and relay outputs on one 9-module DIN device.
• Ethernet + LCD: Direct IP link to Interra panels / HomeServer; local menu and status display.
• 16 A relays: Lighting and loads; mind capacitive inrush (measure before connecting).
• Shutter modes: 24 V (up to 4 outputs) or 230 V AC (up to 2 outputs) configurations.
• Scenarios & logic: Up to 10 scenarios; input/output/virtual logic relationships.
• Mains powered: 100–250 V AC @ 50 Hz; typ. 0.9 W; IP20; RAL 7035 light grey.

Choosing and Commissioning

Choose ITR208-0005 for 8-channel Ethernet I/O; use ITR212-0005 when 12 channels are required. Configure via EIO software over IP (scan or enter address); save/load/copy configurations between devices on the network. Install on 35 mm DIN rail in dry locations; observe insulation between 230 V wiring and contacts. Full ratings and connection diagram are in the Datasheet / Product Manual under Downloads. Interra also publishes EIO commissioning software on the product page.
