I Features

The DigitroniK SDC25/26 is a digital indicating con-

troller featuring multi-range inputs and PID control sys-

tem using new algorithms "RationaLOOP" and "Just-

FiTTER".

Up to two control output points (this number of points

may vary depending on the model) can be used, which

are selectable from the relay contact, voltage pulse, and

current.

The smart loader package ensures easy setting opera-

tion and monitoring.

This controller is compliant to the IEC directives and

the CE marking.

• Space saving design with a depth of 65mm.

• High accuracy of ±0.3%FS and sampling cycle of 0.3s

• Multi-range inputs are available for selection, where

• The control method can be selected from any of the ON/
