Description
Product Overview
The D201130L is an 8-channel digital output module for Metso DNA / D200 DCS system (now Valmet DNA). It converts internal control logic signals into discrete field drive signals to operate solenoid valves, contactors, relay coils and field indicators. Widely deployed in pulp & paper, power plants and chemical process plants as spare replacement for legacy Metso D200 rack-based distributed control hardware.

Key Features
- Eight galvanically isolated digital output channels for driving 24VDC field actuators and relay loads.
- Per-channel status LED indicators for quick local diagnostics of output state and fault conditions.
- Built-in overcurrent and short-circuit protection for each channel to prevent module damage from field wiring faults.
- Seamless integration with D200 ACN controller nodes; receives control setpoints over D200 backplane bus.
- Robust industrial PCB construction designed for continuous operation in control room cabinet environments.
- Supports online hot swap when the D200 system is in redundant configuration.
- Legacy EOL hardware; available as new surplus or refurbished spare for existing DNA DCS fleet maintenance.
Installation & Testing Notes
- Mandatory ESD protection when handling the PCB; static discharge can damage output drive circuits.
- Install only inside compatible D200 rack; verify rack backplane power before inserting the module.
- Check field wiring for short circuits before energizing outputs to avoid triggering channel protection.
- After installation, confirm module OK LED, download control application and perform point-to-point loop testing.
- Validate each channel’s on/off switching and fault detection function.
- Inspect edge connector pins, PCB traces and solder joints for oxidation, bent pins or burn marks before spare deployment.
- Match firmware revision with existing D200 controller to avoid bus communication errors.
FAQ
Q: What system is D201130L for? A: It belongs to Metso (Valmet) DNA D200 DCS, used mainly in pulp and paper mills and power stations.
Q: How many output channels does D201130L have? A: 8 channels of isolated digital outputs, model alias DO8N.
Q: Is it hot swappable? A: Hot replacement is allowed in fully redundant D200 rack configuration; non-redundant racks require system shutdown.
