-
Extensive I/O Capacity: The controller supports a wide array of native and expandable Input/Output points, including:
-
Universal Inputs (UI): Configurable for analog (0-10V, 4-20mA, RTD, etc.) or digital (dry contact) signals.
-
Analog Outputs (AO): Typically 0-10V or 4-20mA for modulating devices like valves and dampers.
-
Digital Outputs (DO): Triac or relay-based for on/off control of fans, pumps, and alarms.
-
-
Robust Networking: Features an integral Infinity (RS-485) LAN port for communicating with other Continuum controllers, field devices, and user interfaces. It also includes an Ethernet port for high-speed, direct connection to the enterprise network, facilitating easy integration with the Continuum workstation and other IT systems.
-
Non-Volatile Memory: All application programs and historical data are stored in flash memory, ensuring no data loss during a power cycle. This guarantees that control strategies resume immediately upon restoration of power without manual intervention.
-
Flexible Power Options: Supports a range of power supply voltages (typically 24VAC or 24VDC), making it adaptable to various electrical infrastructures on-site.
-
Rugged Industrial Design: Housed in a durable, compact enclosure suitable for installation in mechanical rooms, plenums, and other demanding environments.
