ABB Application Controller BACnet/IP, DIN Rail, 24 V AC/DC, 4 UI, 4 DO, 4 AO, 2 Ethernet, KNX, Web Server 2CDG110206R0011

Integrating BACnet/IP networks with KNX installations often requires separate gateways and complex configuration. The ABB Application Controller BACnet/IP (AC/S1.2.1) solves this by combining a BACnet/IP server, a KNX interface, and a programmable logic controller in one DIN-rail module. It enables seamless data exchange and automation across building systems.

Who is it for

System integrators, building automation engineers, and facility managers who need to connect KNX field devices to BACnet/IP building management systems, or who require a compact, programmable controller for HVAC, lighting, and energy management applications.

Main features

• BACnet/IP server (B-BC profile) with integrated web server for configuration and monitoring.
• 4 universal inputs configurable as digital, resistance, 0-10 V, or 0-20 mA.
• 4 relay outputs (24 V AC/DC, 0.5 A) and 4 analog outputs (0-10 V, 20 mA).
• 2 Ethernet ports (10/100 Mbps) for BACnet/IP and programming.
• KNX bus connection via internal bus terminal.
• DIN rail mounting, 6 modules wide, 24 V AC/DC power supply.
• Real-time clock with battery backup for scheduling and time-based control.

Specifications

• Power supply input voltage: 24 V AC/DC
• Power consumption: max. 5 W
• Operating temperature: 0 °C to +50 °C
• Material: Plastic
• Host interface: 2 x RJ45 Ethernet
• Output interface: 4 relay outputs, 4 analog outputs

Tips

Use the integrated web server for initial setup and diagnostics. For larger installations, the controller can be programmed with ABB Automation Builder or other BACnet-compatible tools. Ensure the power supply is stable and within the specified voltage range to avoid unexpected resets.
