1.0 Digital Actuator Model G2 Datasheet
Emech
®
G2 actuators offer all the benefits of intelligent control. High performance closed-loop temperature control is achieved when the
G2 actuator is combined with Emech
®
3-port and 2-port disc valves and sensors. Control with butterfly and other quarter-turn valves can
also be significantly enhanced by the Emech
®
G2 actuator.
Multiple sensor connectivity options and onboard software for stand-alone closed-loop control are included as standard features.
Emech
®
G2 actuators provide compact, configurable, high-speed actuation solutions for 0° - 350° applications and torques up to
885 in/lb continuous.

G2 Actuator Features
G22 Model: 310 in/lb torque, 24vDC 5 Amp
G23 Model: 885 in/lb torque, 24vDC 5 Amp

G2 Actuator Sizes
• Keypad and display allows for full actuator configuration without external
devices required
• Three operating modes:
• Standalone control via onboard keypad and remote control options
• Analog (4-20mA input and output ports)
• Modbus (RS-485)
• Extra digital input for interfacing ancillary devices (e.g. flow switch, level
switch)
• Electrical stepper motor control
• 90° stroke time as low as 1.5 seconds for fast control action
• Precise positioning achieving 0.03° valve seat placement
• Local closed loop control of temperature
• Failsafe position feedback (non-contact absolute encoder)
