Description
Core Product Summary
The Metso D201376 is a D-series analog signal I/O board used within Metso Automation (now Valmet) process control and DCS/PLC systems. It is stocked as a board-level automation spare for plants that operate Metso-based control cabinets, where it handles analog signal processing between field instrumentation and the controller.
The board belongs to the Metso D-series module family alongside boards such as the D201126 DI8 digital input, D201129 DO8 digital output, D201134 AI8 analog input, and D201190 AO4H HART analog output, which are commonly maintained together as a system spares group. An L-suffixed variant (D201376L) is documented in the spare-parts market. One point deserves particular care with this part number: available third-party descriptions do not agree on whether the board’s primary function is analog input or analog output, and no manufacturer datasheet figures in the public research trail resolve it. For ordering purposes, the module type printed on the original board’s own label — read in the I/O rack and checked against the station’s configuration record — is the only reliable identification basis.
Key Technical Specifications
| Parameter | Value |
|---|---|
| Product type | Analog signal I/O board (PLC / DCS control system module) |
| Manufacturer / family | Metso Automation (Valmet), D-series I/O boards |
| Platform context | Metso DCS / PLC process control systems |
| Known variant | D201376L (L-suffixed) |
| Related family boards | D201126 (DI8), D201129 (DO8), D201134 (AI8), D201136 (AO4C), D201189 (AI8H), D201190 (AO4H) |
Channel counts, signal ranges, and resolution figures are intentionally omitted here: the available public material for this exact order number does not include a manufacturer datasheet with those values, and third-party descriptions conflict on the board’s function.
Engineering Selection Highlights
- Function must be verified from the board label, not from listings: Public third-party descriptions of the D201376 split between analog input and analog output roles. Similar Metso board families carry distinct AI/AO designations (AI8, AO4C, AI8H, AO4H), so the type marking on the physical board is the decisive identification.
- Part of the D-series spares group: The D201376 appears consistently alongside the D201126/D201129/D201134/D201136/D201189/D201190 boards in Metso spares listings, indicating it belongs to the same cabinet-level I/O ecosystem. Sites maintaining this platform typically stock these boards as one package.
- L-variant revision check: A D201376L variant is documented. As with the rest of the family, revision differences can carry hardware or firmware changes within the same base order number, so the replacement should match the revision marking of the original board.
- Configuration-record cross-check: Because board functions in this series are sometimes misdescribed by resellers, the I/O station’s configuration database — which records slot position and module type — should be consulted before ordering, alongside the physical label.

Detailed Product Overview
The D201376 is a Metso D-series automation board, and the most useful thing a product page can do for this part number is explain how to identify it correctly rather than assert specifications that the public record does not firmly support. Across the available spare-parts listings, the board is described as an analog input module by most sources, but at least one reference places the D201376L variant as an analog output module, and no manufacturer datasheet for the exact order number appears in the publicly retrievable material. Under those conditions, any confident statement of channel count, signal range, or resolution would be guesswork.
What can be established is the board’s ecosystem. It is consistently listed alongside the core Metso D-series I/O boards — the D201126 DI8 digital input, D201129 DO8 digital output, D201134 AI8 analog input, D201136 AO4C analog output, D201189 AI8H HART analog input, and D201190 AO4H HART analog output. This family populates the I/O racks of Metso (now Valmet) process control systems, and plants running those systems generally manage the whole family as one spares inventory because a single cabinet can contain several of the board types.
For procurement, three verification steps matter. First, read the original board’s label in the rack: the order number, the module-type designation, and any revision marking. Second, check the I/O station’s configuration record, which documents which module type occupies which slot — this resolves the input-versus-output question authoritatively. Third, note that an L-suffixed variant (D201376L) exists, and treat the suffix as part of the part number when matching stock.
The board should be approached as a legacy-platform spare: the practical risk in ordering is not performance but misidentification, and the mitigation is label-and-configuration verification rather than reliance on catalog descriptions.
System Compatibility & Integration Requirements
| Item / Dependency | Verified Compatibility or Requirement | Practical Note |
|---|---|---|
| Control platform | Metso Automation (Valmet) DCS / PLC systems using D-series boards | Verify slot and station configuration against site documentation |
| Family context | Same D-series ecosystem as DI8, DO8, AI8, AI8H, AO4C, AO4H boards | Typically stocked as a group of cabinet spares |
| Revision check | D201376L variant documented | Match the revision marking on the original board |
| Identification basis | Module type marking on the original board’s label | Third-party descriptions conflict on input vs. output function; the label is authoritative |
Applications & System Role
Within a Metso-based control architecture, the D201376 belongs to the analog signal-handling layer of the I/O system — the boards that move continuous measurement or command signals between field instrumentation and the controller, as distinct from the digital boards that handle discrete on/off signals. Its exact position on the input or output side of that layer should be established from the board’s own type marking and the I/O configuration record.
Typical fit scenarios are those common to D-series board spares: restoring an I/O slot after a board failure in a Metso-based cabinet, supporting cabinet expansion, or holding critical-inventory stock in plants whose control systems depend on this legacy platform. It is relevant wherever the site’s spares list calls for the D201376 order number against a specific slot in the I/O station.
FAQ

It is a D-series analog signal I/O board used in Metso Automation (Valmet) process control systems, stocked as a board-level automation spare.
Is the D201376 an analog input or analog output module?
Available public descriptions conflict on this point, and no manufacturer datasheet for the exact order number resolves it. The module-type marking on the original board’s label and the I/O station’s configuration record are the authoritative sources.
Is there an L revision of this module?
Yes, a D201376L variant is documented in the spare-parts market. Match the revision marking on the original board before ordering.
Which boards belong to the same family?
The D201126 (DI8), D201129 (DO8), D201134 (AI8), D201136 (AO4C), D201189 (AI8H), and D201190 (AO4H) are the related boards in the Metso D-series I/O family.
How should I verify this part before ordering?
