High-speed data applications are catered for with the IS-SL485 and IS-SLDH models feature operation up to 20MHz. The IS-SL485 is ideal for applications such as RS485 serial communication and protocols such as Profibus and CAN. Similarly IS-SLDH is designed for other high speed protocols such as Data Highway and Data Highway Plus. Typically, these models are used in conjunction with the EC90 base to provide isolation from earth
