Optimized temperature control

Functions convenient for temperature control are built in

The control unit with thermistor inputs enables temperature control

at low cost

Two thermistor inputs, which cost less than thermocouples,

can be connected to the FP

S (Sigma) unit via thermistor inputs

(FPG-C28P2HTM, FPG-C32T2HTM and FPG-C24R2HTM).

Optimized temperature control with PID and PWM instruction

You can easily set multi-stage temperature control and time

control usually available only in high performance type

temperature controllers.

Various FPWIN Pro libraries simplify the programming of closed loop

controlled electrical installations and consequently save valuable human

resurce costs. The process and temperature control Library NCL-PTC-LIB,

for example, includes linear and non-linear controller types such as the

P/I/PI/PID controller and two-point / three-point controllers with and without

hysteresis. Functions for dead band, interpolation, ramp limiting, dead time

and averaging are also included.

Using a simple linearization command, measuring

the temperature by the thermistor can be programmed easily.

Four- and eight-channel type thermocouple input expansion unit

Up to three units can be added to each control unit, enabling temperature

control of up to 24 channels.

Advantages over multiple temperature controllers:

Information collection and computer-based storage.



On-site error monitoring using programmable display.



Significant reduction in total costs.



Power supply stabilisation by protecting synchronisation



between heater ON and OFF states.

Temperature settings can be easily changed using batch function.
