Isolation enhancement

Introducing the isolation amplifier designed to enhance galvanic isolation from the analog programming connector. It offers enhanced isolation while providing precise analog programming and monitoring capabilities.


This amplifier offers selectable signal levels, between 0-5 V or 0-10 V to accommodate diverse input requirements. With isolated programming and monitoring features, it ensures the integrity of voltage, current, and status signals, mitigating issues associated with earth loops and CM-voltages.


The isolation amplifier is available either as a factory-order built-in option or as an external interface. For more details on this option or external interface, please consult the data sheet. This product is compatible with SM800, SM1500, SM3000, and SM6000 models.
