1.0 Digital Actuator - Model G1
Datasheet
G1 Actuator General Features
Emech G1 actuators offer all the benefits of intelligen
control. High performance Closed loop temperature control is
achieved when combined with Emech 3 and 2 port disc valves and
sensors. Control with butterfly and other quarter turn valves can be
significantly enhanced by the Emech actuato .
Multiple sensor connectivity options, and onboard software for stand
alone closed loop control are included as standard features. Emech
G1 actuators provide compact configurable high-speed actuation
solutions for 0° and 350° applications, and torques up to 885 in.lb
continuous.
Two sizes:
G12 model 310 in.lb torque: 24vDC 3.5 Amp
G13 model 885 in.lb torque: 24vDC 5 Amp
