  • The Model 2-B Mini-RTU is designed for use in medium to large substations. The dimensions of this larger unit are 16.25″x19″x4″.
  • Thirty-two digital inputs can be independently configured for Active-HI or Active-LO operation. A separate set of contacts on the input relays can be used for local alarms (lamps or other annunciators) near the RTU.
  • Twelve-bit resolution is featured on the 48 single-ended analog inputs, pre-scaled to ± 1 VDC with 0.1% accuracy.
  • They can be configured for DNP 3.0, Modbus, PG&E (Data 2179), Telegyr 8979, or CDC Type I / II protocols.
  • They can be daisy-chained for additional points on a single communication line.
  • The Mod 2-B comes with a free copy of the VisiCal software suite that allows it to be configured, calibrated, scanned, monitored or programmed with drag-and-drop and pushbutton simplicity.
