GENERAL ACTUATOR DESCRIPTION
The GPSA is a high precision linear actuator. It is
capable of producing 200 pounds of force over its 1.38
inch stroke length at a speed of up to .13 inches per
second. At a speed of .25 inches per second the unit is
capable of producing 100 pounds of thrust.
It can utilize up to three input signals, independently
configurable as either current (4-20 ma) or voltage
(1-5 V) for control. Two dry contact inputs are
available and may be configured to energize or de-
energize on fault. The actuator provides three output
relays which are configurable as to their trigger and to
act as NO or NC. A position feedback signal is pro-
vided via a 4-20ma transmitter, which is configurable
as either internally powered or externally loop
powered.
A two line, 16 character VFD display and rotary
switches comprise the actuators HMI. This provides
access for viewing and modifying changeable
parameters and data feedback.
