Suntest IRDS-VA. Digital Amp Module For Proportional Solenoid Valve

Manufacturer: Suntest Co.,Ltd
Model: IRDS-VA

This is a slave module for proportional solenoid valve amp of IRD series.
It receives command signal from the host system through the industrial network and outputs current to proportional solenoid valve.

*Not possible to drive servo valve, proportional solenoid valve having LVDT inside or integrated amplifier.

[ Function and Features ]

Driving one proportional solenoid valve with 1800mA or 1000mA.
Possible to set or change inside parameters through IRD master module over the industrial network or the dedicated Windows software (IRD Manger).
Setting Max. and Min. current output values.
Possible to drive with switch signal to the valve as well (switch : max. 16 points). For directional flow control valve, 16 points for one direction, total 32 points.
Setting current output value (for ON and OFF) and each time constant. With emergency stop function.
Monitoring output current value and I/O signal status.
RoHS compliant
