CEM-AC-E0-A
CEM-AC-E1-A
Description:
This power amplifier mounts directly to a single solenoid proportional valve coil with a DIN style
connector, and will drive up to 2.5A. It is suitable to control current to either a proportional flow or
pressure valve coil.
A wide range of analog signals are accepted. There are two product choices for input, one
accepts voltage commands, the other accepts current commands. These inputs are easily scaled
to match system requirements. Two independent ramps are available for acceleration and
deceleration control.
Min and Max output current are adjustable. Output characteristics can be independently
customized. The module is disabled if the coil outputs are shorted or open. If command current is
outside of the proper range, the module is also disabled. PWM and Dither are user adjustable.
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.
