Continental Hydraulics CEM-SD – Closed Loop Pressure Amplifier

~ scroll down to find the part you need ~
Continental Hydraulics are at the forefront of engineering hydraulic solutions for over 50 years-a testament to a long-standing reputation built upon your challenges and opportunities. A worldwide leader- a one-stop-shop for valves, pumps, power units and proportional products-all assembled in the USA.
The Continental Hydraulics CEM-SD closed loop position module is designed to quickly and accurately move hydraulic cylinder loads.
Position and velocity commands are from analog sources. Cylinder position feedback is from a digital (SSI) source.
Stroke dependent deceleration is used to provide quick and repeatable positioning. Internal ramp and velocity adjustments allow for easy system
A wide range of analog signals are accepted. User may select either voltage or current input mode. These inputs are easily scaled to match system.
Forward and Reverse “jog” inputs allow for manual load control. A user definable window for “in position” triggers an output for communication to the next machine function.
Output is an analog voltage, 0 to +10vdc , suitable for directly driving a proportional directional valve with on board electronics.
This module is easily adapted to a variety of system requirements. All variables are user adjusted with easy to use software on your Microsoft Windows® laptop.
Control variables are stored in non-volatile memory internal to the module. All variables can be read by the laptop, and reproduced exactly on other modules.
