TM

Digital Indicating Controller

SDC40A

The DigitroniK TM SDC40A is a compact (96mm x 96mm) digital controller. The SDC40A features a wide variety of input options: thermocouples, resistance temperature detectors, DC voltage and DC current inputs are supported.

Control outputs consist of time proportional PID (relay output, voltage output), current output PID, position proportional

PID, and heat/cool PID. The SDC40A simplifies control with

PID auto tuning and systems. The SDC40A can optionally be provided with a maximum of 12 remote switch inputs and a maximum of 8 event outputs for automatic operation in combination with a PLC.

Variable gain If the load characteristic of the control system is non-linear, stable control characteristics are obtained by changing the gain according to the deviation. Control conforms to the following equation:

Set proportional band (p) X

Gain value

= Real proportional band.

Set value range: 0.01 to 300.00

Gain 1: when –20% FS

Gain 5: when 0% FS

Gain 6: when 2% FS

Gain 7: when 5% FS

Gain 8: when 10% FS

The gain ramp is automatically calculated using set gains, when the deviation is less than –20% or more than

20%, calculation uses the extended characteristic.
