Features:
- Each of the four channels can be independently configured for current or voltage output; 16‑bit resolution; ±0.1% accuracy; supports control of valves, VFDs, and actuators
- Module can be replaced under power without system shutdown; 250V AC channel‑to‑ground isolation prevents ground loops and protects the controller; ideal for high‑availability processes
- LED indicators for power, communication, and channel status; automatic online recalibration; open/short circuit detection; software configurable fail‑safe modes (hold last value or set to safe value)
The A413135 AOU4 is a 4‑channel analog output module that serves as the interface between the Valmet DNA DCS and final control elements such as positioners, I/P converters, variable frequency drives, and actuators. Each of the four channels can be independently configured via software to output either 4‑20 mA (or 0‑20 mA) current signals or ±10 V voltage signals. The 16‑bit resolution provides 65,536 discrete steps over the full range, enabling extremely fine adjustments.
In continuous process industries such as pulp and paper, power generation, and chemical manufacturing, unplanned downtime is measured in thousands of dollars per minute. The A413135 AOU4 addresses this by supporting hot‑swapping – the ability to remove and replace a faulty module while the system remains powered and operational. Only the output channels on the failed module are affected; other I/O continues normal operation. This feature dramatically reduces mean time to repair (MTTR) and eliminates the need for a full system shutdown for routine maintenance.
The A413135 AOU4 includes a suite of diagnostic features that simplify troubleshooting and ensure long‑term accuracy. On the front panel, LED indicators show power status, communication activity, and per‑channel fault conditions (e.g., open circuit, short circuit, or overload). These visual indicators allow a technician to instantly identify a faulty channel without any test equipment. Internally, the module performs automatic self‑calibration at power‑up and periodically during operation. This online recalibration compensates for component aging and temperature drift, maintaining the specified ±0.1% accuracy over the entire operating temperature range (-25°C to +70°C).
The A413135 AOU4 Metso Auttomation Analog Output Module may still be available for purchase and support from Apter Power beyond
End-Of-Life (EOL)by the manufacturer (OEM).

- Power Generation: Used in power plant control systems for regulating turbines and balancing electrical loads.
- Pulp, Paper, and Energy: Common in Valmet (formerly Metso) Damatic DNA environments to manage complex chemical and thermal processes.
- Minerals & Mining: Controls equipment like crushers, screens, and conveyors in minerals processing plants.
- Field Device Control: Specifically drives control valves, actuators, and signal converters where precise 4-20mA or 0-10V positioning is required.
- Output Channels: Features 4 analog output channels providing high-resolution signal transmission (typically 14-bit or higher).
- System Integration: It integrates seamlessly with Valmet/Metso DNA control stations (ACN controllers) via a dedicated backplane or Ethernet field bus.
- Field Communication: Supports standard industrial signal loops and is often HART-capable, allowing for remote diagnostics and configuration of connected smart instruments without additional hardware.
- Diagnostics: Includes LED status indicators on the front panel for immediate visual confirmation of power, communication health, and channel status.
- Electrical Isolation: Provides significant isolation (e.g., channel-to-channel and field-to-logic) to protect sensitive control electronics from field-side electrical surges.
- Cybersecurity: As part of the Valmet DNA ecosystem, it adheres to high cybersecurity standards, including ISO 27001 and IEC 62443-4-1.
- Environmental Resilience: Designed for harsh industrial environments, with optional G3 conformal coating to resist corrosion in chemical-heavy atmospheres.
- Redundancy: Supports system-level redundancy configurations, ensuring that a single module or cable failure does not cause a process shutdown.
