CN612TC1 / CN612RTD2

Power 120/240 VAC



The CN606 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  enabled  zones cross Lo alarm setpoint.

 The CN606 Series implements a security password

to protect certain functions.
