Power output
Proper parameters of maximum current, PWM, dither and set the output supplied to
solenoids.
Separate parameters are available for each output channel in EDM-M3 card version (two
valves with single solenoid)
Moreover, the output value can be compensated using the deadband compensation
parameter set.
The maximum current that can be provided to a coil is 120% of the CURRENT parameter.
The upper limit of CURRENT is set by CURRENT_LIM parameter and it can’t go over the
maximum current of 3600 mA for the output a 2600 mA.
Analog input
Analog inputs type can be selected by SIGNAL_TYPE parameter and signals can be scaled by
SIGNAL_OFFSET and SIGNAL_GAIN parameters.
M1 version (for one valve with one coil) require unipolar voltage (0…10 V) or current signal
(4…20 mA)
M2 version (for one valve with two coils) generates a proportional current on solenoid A with
a positive value of voltage or a current between 12…20 mA and a proportional current on
solenoid B with a negative value of voltage or a current between 4…12
mA.
M3 version (for two valves with one coil each), requires that both the analogue inputs must be
used.
