TEMPERATURE -30ºC to +1370ºC INDICATOR / MONITOR incl 24h TIMER THERMOCOUPLE NOT INCLUDED
This device incorporates a digital temperature controller and a 24 hour timer with two “on” times and two “off” times.
The two functions operate independently and control separate relays.
The temperature controller interfaces directly with Type J,K,R,S,N,T & E thermocouples and offers adjustable hysteresis, offset, maximum and minimum set point limits.
The relay may be configured for heating or cooling applications.
In case of a power failure the clock’s time is saved to non volatile memory. When the power is re-applied, the clock continues from where it left off.
The menu can be reduced and the parameters locked with an access code to protect programmed values
Temperature must rise to set point value before relay de-energizes, then it must drop by the hysteresis amount before being re-energized.
Temperature must drop to set point value before relay de-energizes, then it must rise by the hysteresis amount before being re-energized.
The timer relay is energised whenever the clock’s time falls between “ON 1” time and “OFF 1” time, or “ON 2” time and “OFF 2” time.
