CEM-AA-B
Description:
This adaptable power amplifier is configurable to drive either single or dual solenoid, or two
independent proportional valve coils up to 2.6A. A wide range of analog or digital signals are
accepted dependent on the configuration. User may select either voltage, current or digital input
mode. These inputs are easily scaled to match system requirements.
The CEM-AA-B module has three selectable function modes:
Function mode AA
for operating one single or dual solenoid Proportional Control Valve
Function mode A-B
for operating independently two single solenoid Proportional Control
Valves
Function mode RA
, This mode accepts 3 independent switch inputs, each which has
independently adjustable speed and ramp controls. Inputs are additive, for up to 8 unique
preset speed and ramp profiles.
Independent Ramp of acceleration and deceleration, IMIN and IMAX, PWM, DITHER settings are
programmable. In addition the valve characteristics can also be linearized via 10 X-Y points per
solenoid output.
The module is disabled if the coil outputs are shorted or open. If command current signal is
outside of the proper range, the module is disabled.
This module is easily adapted to a variety of system requirements. All variables are user adjusted
with easy to use CHI-PC 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.
