Carlo Gavazzi Solar PV Eos-Array Master Module/Data Logger, VMU-M4AS1T2X

Carlo Gavazzi Energy Management Control Solution For Solar PV Application, Eos-Array Master Module & Data Logger, Input: 2x Temperature or 2x Digital, 12-28VDC, RS485 Communication

Eos-Array is a combination of modules which performs a complete control of a photovoltaic plant. The core unit is VMU-M which performs the local bus management of VMU-S, VMU-P both measuring units and VMU-O I/O unit. VMU-M assigns the proper local unit address automatically (up to 15 units) and gathers all the local measurements coming from VMU-S and VMU-P measuring units. VMU-M can provide by means of VMU-O modules two relay outputs so to manage alarms or/and external loads (like a lighting system, a module washing system and so on) and two temperature inputs. These latter two measuring inputs can become, according to the programmed function, also two digital inputs. Housing for DIN-rail mounting, IP40 (front) protection degree.
