VMU-M, master module and data logger • Master communication capability • RS485 communication port (Modbus) • Local communication bus management up to 15 mixed VMU-S, VMU-P and VMU-O units • Two digital inputs • Two temperature inputs: Pt100 or Pt1000 • Single virtual or real alarm set-point connectable to any available variable • Data and event stamping system • Display readout: 6 DGTs • 12 to 28 VDC power supply • Dimensions: 1-DIN module • Protection degree (front): IP40 Product Description How to orderVMU-M4 A S1 T2 X Eos-Array isa combination of moduleswhichperforms a complete control of a pho- tovoltaic plant. The core unit isVMU-Mwhichperforms thelocalbusmanagement of VMU-S, VMU-P both measuring units and VMU-O I/Ounit.VMU-M assigns the proper local unit address automatically (up to 15 units) and gathers all the local measurements comingfrom VMU-S and VMU-P measur- ingunits.VMU-Mcanpro- vide by means of VMU-O modulestworelay outputs so to manage alarms or/and external loads (like a lighting system,a modulewashing 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 mount- ing, IP40 (front) protection degree.
