IMC-P111FX / IMC-P111P M12 Series

Industrial IEC 61850-3 Ethernet to fiber media converter with 1x10/100Base-T(X) M12 connector to 1x100Base-FX fiber or 1x100Base-FX SFP socket



IMC-P111 M12 series is a cost-effective solution for the conversion between 10/100Base-T(X) M12 connector and 100Base-FX interface; it allows you to extend communication distance by optical fiber. IMC-P111 M12 series are designed for power substation application and rolling stock application, fully compliant with the requirement of IEC 61850-3 and IEEE 1613. IMC-P111 M12 series supports MDI/MDIX auto detection, so you don’t need to use crossover wires. IMC-P111 M12 series Ethernet switch use M12 connectors to ensure tight, robust connections, and guarantee reliable operation against environmental disturbances, such as vibration and shock. IMC-P111 M12 series with wide operating temperature range from -40 ~ 85oC and accepts a wide voltage range power inputs, so it is suitable for harsh operating environments.

IMC-P111 M12 series also support the LFP (Link Fault Pass-through) feature. When one side of the link fails, the other side continues transmitting packets, and waiting for a response that never arrives from the disconnected side. Use the DIP-Switch to enable the LFP function, then IMC-P111 M12 series will force the link to shutdown as soon as noticed that the other link has failed, giving the application software a chance to react to the situation. Therefore, the IMC-P111 M12 series is reliable media converter and can satisfy most demand of power substation and rolling stock application.
