Cat MX350 Controller
MX350-controlleren er specielt designet til lavspændings ATS-applikationer (Automatic Transfer Switch) Denne controller er meget fleksibel og dermed velegnet til en lang række opgaver. MX350 har integrerede trykknapper, grafiske displays og LED-indikatorer, hvilket reducerer behovet for tilslutning af eksterne kontrol-enheder. Samtidig muliggør det lokal kontrol og lokal adgang til systeminformation. MX350-controlleren kan både kommunikere via RS-485 serial og 10/100 base-T Ethernet og understøtter også de åbne kommunikationsprotokoller Modbus RTU og Modbus TCP. Denne alsidighed muliggør enkel integration i mange overvågnings- og kontrolsystemer.
