Typical Applications
Features:
Programmable: User friendly keys allow for easy programming of the timer, temperature control and programmable parameters.
Three Output Types: Relay, SSR Driver or Triac outputs available.
Status LEDs: LEDs on the front panel provide visual indication of output and alarm status.
Dual Digital Displays: Seven segment LEDs display the time, the temperature and the programmable parameters.
Input Flexibility: Programmable for thermocouple or RTD input.
Program Security: Programmable values are protected against unwanted operator access through the use of a multi-level, multi-key programming architecture.
Non-Volatile Memory: All programmable values are stored in EEPROM.
Timer Pause Band: Automatically pauses the timer whenever the process temperature moves outside this band.
Control Flexibility: Temperature control can be programmed to be On/Off or Proportional, Heating or Cooling and °F or °C.
Built-in Beeper: Built-in beeper provides audible indication.
1Ž4 DIN Enclosure: ABS plastic, 1/4 DIN size enclosure facilitates mounting and wiring.
Three Timer Ranges: Timer is programmable for Min./Sec., Hours/Min. or Hours only.
Fail Safe: Open or short circuited input de-energizes output(s).
One, Two or Three Outputs: Units can be ordered with up to three outputs. Outputs can be programmed as temperature control, fan or high and/or low alarm outputs.
The CN530 series is a unique microprocessor-based, fully programmable, combination temperature and timer controller. It is ideal for use on "batch" type equipment where accurate time and temperature "cycles" are required to produce a high quality end product. The CN530 combines both temperature and timer functions into a single 1Ž4 DIN size enclosure. This facilitates both mounting and wiring which reduces installation and labor costs.
The CN530 is an economical alternative to individual electromechanical or electronic timers, thermostats, and temperature controllers. For foodservice equipment applications, the CN530 offers many of the same features found on "cooking computers" at a fraction of the cost.
Large easy to read digital displays on the CN530 show both temperature and timer simultaneously. Additional visual indication is provided by front panel LEDs. A built-in beeper audibly informs the user that the "cycle" is complete. Programming the CN530 is made easy through the use of a menu driven programming structure with user friendly prompts.
Versions are available with one, two, or three outputs and with RTD or thermocouple input. Outputs can be programmed as temperature control, fan, or high and/or low alarm outputs.
