GENERAL SPECIFICATIONS
Construction
: Plug-in
Connection
: M3.5 screw terminals
Screw terminal:
Chromated steel
Housing material
: Flame-resistant resin (black)
Deadband
: Automatically adjusted from 0.1 to 2 % of span to avoid hunting
Output delay
: Approx. 0.5 sec. from an input change to the output in order to protect the internal motor; when the input continuously or repeatedly changes, there is approx. 3-sec. delay after the output becomes steady and then resumes changing.
