The ABB ISP/S 8.1.1.1 IP Switch-PoE (order code 2CDG120083R0011) is an 8-port Fast Ethernet MDRC switch with integrated Power over Ethernet. It delivers data and supply to compatible IP endpoints — typically ABB IPS / IPR devices that accept IEEE 802.3af class 1 — so many panels can avoid separate PoE injectors or a dedicated 24 V rail for every IP interface.

ABB product literature rates the total PoE budget at about 55 W. Plan port loading so the sum of powered devices stays within that budget and within each port’s class limits. ISP/S is Ethernet/PoE infrastructure: it has no KNX ETS application. Net weight is approximately 0.41 kg.

If you only need switching without PoE, use IS/S8.1.1 and feed endpoints from CP-D 24/2.5 or another approved auxiliary. Pair either switch with IPM/S1.1 when you need tidy patch/breakout in the board.

Key Features — PoE Panel Switch

• 8 × Fast Ethernet with PoE: Power and data for compatible IP KNX devices from one MDRC unit.
• ~55 W PoE budget: Size the number of class 1 loads against the total power envelope.
• Fewer auxiliaries: Often removes the need for per-device 24 V PSU or injectors for IPS/IPR.
• MDRC installation: DIN-rail network gear next to KNX bus components.
• No ETS device file: Commission as LAN/PoE infrastructure, not as a KNX TP application.
