SL209PI-T0121 Proportional-Integral Controller

   Abstract:

SL209PI-T0121 is one has two control loop independent intelligence general controller,
each control loop can be applied to two PI controls and four switch controls;
SL209PI-T0121 has the 1NTC thermistor sensor (internal) inputs,1 analog input;
SL209PI-T0121 also has two digital outputs and one analog output.These outputs needs
through the software programming to choose specific control loop.SL209PI-T0121 has
the formidable control function,users only need to change the parameter setting ,and
the control requirements can be achieved ,without the need for other tools or software
programming and so on.
