Temperature Process Controllers

The controllers placed in this category are designed not only for keeping specific temperature in given limiting values but they have additional functions. These devices are multifunctional programmable controllers for temperature processes and transmitting information to other controller or computer.

The controllers are equipped with relay outputs and RS485 channel for data transmission and network relations.

SM927 may be specified as P, PI, PD, PID, ON-OFF controllers only by changing software parameters. There is internal function AutoTune which detect specific conditions and peculiarity of the controlled object and automatically changes the parameters into the controller to reach smallest possible diversion (some specific applications required additional manual changing of internal parameters).

The controller can work in three regimes: one set temperature; program set temperatures and network setting temperature. It is possible to set seven steps. Each one contains three parameters – temperature, regulating time and temperature growing speed.
