Auto Mains (Utility) Failure Control Module

The DSE7420 MKII is an intelligent, powerful auto mains (utility) failure control module with high-level features and functionality. The control module is the first module in the DSE range to include in-built SNMP and features an embedded web server. The module is suitable for a wide range of single-set gas and diesel applications. 

The control module features an enhanced dual core main processor and extended memory capacity. This allows the module to deliver a faster more powerful performance to return quicker operating responses on complex applications and provides enhanced memory storage for high level data logging functionality.
