Product 7/9
Description:
This controller has been upgraded with many new features. The cold junction compensation circuit has been improved for better accuracy when used with thermocouple sensor. A true on/off control mode is added. It is useful for controlling a refrigerator, motor, or solenoid valve that does not like to be switched too frequently. User can set the temperature and hysteresis band. It will work like a mechanical thermostat with better accuracy and tighter temperature range. A manual control function is also added. The manual control mode allows the user to control the heater power just like a dimmer switch for the light bulb. This is a useful function for the beer brewer to control the strength of boiling. The latest addition is the limit control function. It can be used for safety protection. When connected to a contactor or SSR, it can function as a latching relay. It will shut off the system if the temperature is out of control. The heater will not be turned on until reset manually. The limit control is also useful for applications that once the set temperature is reached, the system needs to be shut off automatically. e.g., ceramic kiln firing, meat cooking, and distillation. All of the control mode can be set for either relay output or SSR control output by the user.
