METSO A413665: 8-Channel Analog Output Module
The METSO A413665 is a configurable 8-channel analog output module engineered for seamless integration into Metso Damatic XD and Valmet DNA automation platforms. It delivers precise 4-20mA current or 0-10V voltage output signals to drive positioners, I/P converters, variable frequency drives, and other analog actuators. Each channel features 16-bit DAC resolution, individual channel isolation, programmable output ranges, and advanced diagnostics including open-loop detection and load monitoring. Housed in a rugged DIN-rail mountable enclosure with conformal-coated PCB, the module operates from -20°C to +60°C, meets CE/UL standards, and supports hot-swap replacement. It is ideal for pulp & paper, power, chemical, oil & gas, and water treatment applications requiring reliable and precise analog control.
Platform Compatibility
The A413665 is a universal analog output module for Metso Damatic XD and Valmet DNA distributed control systems. It mounts in standard I/O racks or can be used as a standalone field module with optional IP65 enclosure. Full characterization within Valmet DNA Workbench ensures plug-and-play configuration.
Key Features and Functional Capabilities
8 Independently Configurable Outputs: Each channel can be individually set for current (0-20mA, 4-20mA) or voltage (0-5V, 0-10V, ±10V) output via software, eliminating the need for external converters.
High-Resolution 16-Bit DAC: Integrated digital-to-analog converter per channel provides exceptional setpoint resolution and low output ripple, ensuring smooth actuator response and precise positioning.
Galvanic Isolation: Channel-to-backplane isolation 1500V AC, channel-to-channel isolation 500V DC. Prevents ground loops and protects controller electronics from field transients.
Advanced Output Diagnostics: Per-channel open-wire detection (for current loops), load resistance monitoring, and overrange/underrange alarms. Module-level status LEDs for power, communication, and fault.
Programmable Ramp/Slew Rate: Software-selectable output slew limiting prevents abrupt actuator movements that could cause process upsets or mechanical stress.
Robust Industrial Design: Conformal-coated PCB (IPC-CC-830B) resists humidity, condensation, and corrosive gases. Operating temperature -20°C to +60°C, storage -40°C to +85°C. Vibration and shock tested per IEC 60068-2-6/27.
Hot-Swap Capable (Rack Version): Module can be replaced while backplane is powered without disturbing adjacent I/O modules, minimizing process downtime.
