Device

SICAM P850 is designed as panel flush-mounted devicewith a graphical display for displaying measured values andparameterization: SICAM P850 (7KG850xxx). SICAM P850 isalso available as DIN rail devices without displays.Ethernet communication uses the Modbus TCP or IEC 61850communication protocol. Serial communication is optionallyavailable with an RS485 interface via Modbus RTU orIEC 60870-5-103.The front protection class is IP20 for DIN rail devices withoutdisplays. Devices for panel flush mounting with displays haveprotection class IP40 or IP51.
