Temperature Scanner

ICD Temperature Scanner Model No. SCN525 is capable to measure and control the  Temperature  upto  16  points.  It  accepts  temperature  sensors  like  RTDs, Thermocouple, mV and mA signals  from Transmitters. The Scanner is completely user programmable  like High/Low set point control action, Auto/Manual operation, Channel grouping, Hold, Pause etc.

The Scanner is a single board construction with the latest integrated circuit, so as to reduce  component  counts.  Fast  A/D  converter  is  used  for  quick  refreshing  of  all  the channels input and output. Digital Zero / Span calibration eliminates trim pot adjustments and settings are made  through key pad.

Maximum 4  relay outputs are given  for Alarm & Trip controls. Channel grouping optional and control modes are programmable.The  Scanner  scans  all  the  channels  continuously  on  the  background  while displaying  and  generates  the  Alarm  &  Trip  outputs  after  comparison  with  respective settings.

The Scanner has  two modes of operation:
1. Operator Level and,
2. Superior Level

The operator level permits channel display selection in Auto, Manual, Hold mode and Alarm acknowledge. Whereas supervisory level access, Alarm & Trip setting, group configuration, output delay adjustments, channel pause  function, scan  time etc.

Optionally, external relay box containing Max. 32 relays can be connected through serial  link. The scanner  is housed  in 96 x 192 x 250 mm  flush mounting enclosure.
