Application scenarios
Pneumatic valve control in industrial automation systems
For controlling EBRO pneumatic valve actuators in industrial automation systems. Supports on/off applications and connects to control systems via SIO binary signals, analog signals, or IO-Link, outputting status signals such as closed, open, fault, or intermediate position.
Modulating control of pneumatic valves
For modulating valve control with single- or double-acting pneumatic actuators. Supports 4-20 mA or 0-10 V analog signals and captures the actual valve position via 90° non-contact position detection.
IO-Link valve condition monitoring and configuration
For EBRO pneumatic valve actuators with IO-Link communication. Device configuration is performed via IO-Link, and device condition is monitored using position, acceleration, and temperature sensors, with on-site status indication provided by the RGB LED.
Pneumatic valve control in potentially explosive atmospheres
For on/off or modulating control of EBRO pneumatic valves in potentially explosive industrial environments, provided the customized ATEX 3GD or ATEX 2GD version is selected.
