IMC-661P is an unmanaged industrial PoE+ media converter for outdoor applications. It is built with industrial-grade components, enclosed in IP30 aluminum casing, and designed to withstand vibration, shock, free fall, and temperatures ranging from -40°C to 75°C.  It is equipped Auto MDI/MDIX (medium dependent interface /MDI crossover), LFS (Link Fault Signaling), LLB (Line Loopback), LEDs, and DIP switches for easy plug-n-play and monitoring.


Robust Electrical and Electromagnetic Safeguard
Engineered to withstand EMI (electromagnetic interference), ESD (Electrostatic discharge), power surge, over voltage, over current, and reverse polarity.
High-Power Budget for PoE Devices
Up to 30W per port powering to both IEEE 802.3af PoE and IEEE 802.3at PoE+ compliant devices.
User-friendly Monitoring of Signal Strengths and Faulty Links
LFS (Link Fault Signaling) for easy determination of optical signal strengths and detection of faulty links on both copper and fiber ports.
Redundant Power System
Powered simultaneously with two different power sources, e.g. SDR-480P-48 power supply and IRA-120/IRA-160 DIN-rail mountable AC to DC power adapter, with power failure alarm.
