TTC.. Electric heating controller

210...415 V, 25 A, DIN mounting
For control of electric heating coils or radiators. The controllers pulse the whole load on/off and utilise
time-proportional triac control. Automatic control function adaptation, P- or PI-control. The controllers
can also be controlled by an external 0...10 V DC signal.
