Main features

Fast sampling of 0.025 sec.

Feedback control with sampling time of 0.025 sec. enables handling of fast changing process applications

PID and other parameters can be set in the unit of 1/100 seconds

Max. 2-CH control on a single instrument

Switchable between 1-loop, 2-loop, and cascade control.

Direct access keys

Switching between Auto/Manual, Remote/Local, Run/Stop is quick using direct access keys.
※Direct access keys can be disabled to prevent accidental key operation.

PFF (Power Feed Forward) input for excellent control stability

Excellent stability can be achieved using Feedforward control by detecting voltage fluctuation of the controlled object.
