Standards & Approvals

blank: Without CE

/CE: CE marking

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.

Isolation

Power input code K, R:

Input to to output to power

Power input code M2:

Input to to output to power to FE

Zero adjustment: -20 to +20 % (input) (front)

Span adjustment: 80 to 120 % (input) (front)

INPUT SPECIFICATIONS

■ DC Current:

Shunt resistor attached to the input terminals (0.5 W)
