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.
