Key Features

Benefits

• Reduces the need for additional interface hardware in some installations due to integrated digital and analogue signals.
• Supports remote operation and commissioning, reducing site visits for routine parameter changes.
• Allows centralised management of multiple devices within one system manager.
• Provides local and network-based connectivity options for system integration.
