The CN612 Series is a second generation of industrial scanners based on the field proven CN600 six zone temperature monitor/alarm system. Several models and options are available.  The CN612 Series is a microprocessor based scanner which accepts signals from thermocouples or RTD's. In the basic unit, six zones are sequentially scanned with a selectable display rate of 1 to 40 seconds each. A single output relay is provided to indicate an alarm condition on any zone. The faceplate has been arranged to call attention to an alarm condition by flashing the main temperature display and indicating the zone in alarm with a flashing zone number display. To prevent alarm on startup, Lo alarm is not activated until all enabled zones cross Lo alarm setpoint. The CN612 Series implements a security password to protect certain functions.
