Digital output
Valve control component for gas group IIB, 60 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.
This driver is suitable for switching solenoid valves or alarm devices.
