Product Description:

This temperature controller offers great value for its price as it is accurate, smart, reliable and equipped with more features than most controllers on the market. The artificial intelligence enhanced PID algorithm and auto-tune function will control the temperature within one degree accuracy without complicated PID parameter fine tuning. This controller is not only made with all the primary functions of an industrial grade PID controller but also made simple for the amateur user. 

This controller has been upgraded with many new features. 0 - 20 mA and 4 - 20 mA linear outputs can be used to drive proportional valve. Relay output can be used to drive small load or mechanical contactor. The cold junction compensation circuit has been improved for increased accuracy when used with thermocouple sensor. A new true on/off control mode is useful for controlling a refrigerator, motor, or solenoid valve that does not favor frequent switching. Users can set the temperature and hysteresis band. It will work like a mechanical thermostat with increased accuracy and tighter temperature range. A manual control function is also added that allows the user to control the heater power just like a dimmer switch for a 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 that can be used for safety protection. When connected to a contactor or linear load, it can function as a latching relay that 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 automatic shutdown applications when a certain temperature is reached. e.g., ceramic kiln firing, meat cooking, and distillation. All of the control modes can be set for either relay output or linear control output by the user.

Two models are available: SYL-2381-mA is the standard model. SYL-2381-mA-S is the model with RS-485 (Modbus_RTU). SYL-2381-mA-S has all the features of SYL-2381-mA, plus the RS-485 serial communication feature. User can use host (like PLC, Arduino, Raspberry Pi or computer) to get access to this controller over RS-485 port.  

Note: SYL-2381-mA and SYL-2381-mA-S cannot drive SSRs.
