Nippon india has developed micro-processor based scanner having 8/16/24/32 channels which are able ti accept process signals either rtd or thermocouple or analogue [vdc or madc] as well as rtd [pt-100, pt-500, pt-1000, cu-10, etc] thermocouples [all type], analogue [various ranges]. The company provide these temperature process scanners with a front-panel scalable analogue input display and built-in 2 relay for hi and lo alarm output. The alarm hi-lo is individual settable per channel as well as individual input sensor per channel. The temperature process scanners with 8/16 channel have 1 common led indication for hi-lo condition while 24/32 channel scanners have individual led indication for alarm, programmable scan rate, etc. These temperature process scanners come with optional feature like printer interface with rtc for 16/18 column printer, rs232/rs485 computer interface, rs-485 for separate relay box for individual hi-lo relay per channel for 8/16 scanner.
