We have the pleasure to introduce new NetControl model 4RU1SH2S specially designed for full control and monitoring in accumulator (12/24/48VDC) powered systems: accumulator current in both directions is measured (with external shunt), accumulator voltage is measured too. Additionally 4 normally closed relay outputs provide user the ability to control power load automatically or manually (remotelly via Internet or the SmartSpaceCloud). Two connectors are available for external sensors for temperature, hummidity etc. (for more info visit Accessories menu).
