GDB Series 28 lbf (125 N) Linear Stroke

  • Floor distribution

  • Registers

  • Short stroke dampers

Feature

Function

Benefit

28 lbf (125 N) Nominal Force

Appropriate force for small dampers

Provides linear force to operate damper actuators up to 8 sq. ft.

Floating (3P) and Proportional Control

Variants available for floating or proportional analog controllers

Compatible with all common controller output signals

Position indicator

Visual indicator of position

Allows quick and easy troubleshooting, set-up, and commissioning

Position feedback available

0-10 v (proportional)

Provides accurate feedback regarding actual position

Self-adapting (proportional control)

Automatically calibrates to actual stroke of application

For applications with less than full physical stroke available, actuator will scale full signal input range to fit actual stroke

Adjustable auxiliary switches available (Floating control)

Provides accessory switching

Adjustable position allows accessories to be switched on/off or position proofs

Direct/Reverse acting

Select input signal operation of direct acting (0-10Vdc) or reverse acting (10-0Vdc).

Operate two actuators off one signal
