Digital output
Valve control component for gas group IIC, 35 mA
The ACT20X-SDI-HAO-S solenoid/actuator driver takes a switched input from e.g. a safe area controller and
delivers an corresponding output to operate an actuator in a hazardous area, e.g. Zone 0. It is available in a
single-channel or double-channel version.
