GENERAL SPECIFICATIONS

Construction: Plug-in

(3.15)

Operation mode: Front-accessed DIP siwthces; direct or

reverse operation; failsafe operation when there is no

position input signal (full-open, full-closed or stop)

Connection: M3.5 screw terminals

136

(5.35)

mm (inch)

Screw terminal: Chromated steel (standard) or stainless

steel

Housing material: Flame-resistant resin (black)

Deadband adj. (control output): 0.25 – 4 % (front)

Restart limiting timer: Approx. 1.5 seconds

Lock protection timer: Power supply to the motor is stopped

when the feedback signal does not enter to deadband for

approx. 2 minutes; reset by power off or by repeating 0 %

and 100 % setpoint input.
