BAS-3018BC module communicates via a BACnet MS/TP Server, serial RS-485-based protocol in master or slave modes for building automation. There are eight isolated, universal input channels, each individually configurable, with sensor input types such as RTD, either Pt-100 or Pt-1000; thermistor, either 3K or 10K; as well as common analog input signals such as 4-20mA or 0-10 VDC.
