Product Introduction

Architecture Hook

Inside the RMS-EX1 expandable refiner-monitor rack, the HPM-RM1 occupies an internal monitoring position and handles hydraulic-pressure measurement associated with the refiner’s hydraulic system. Its stated function is to excite and measure pressure transducers on both the A-chamber and B-chamber sides. The specified sensor type is a 2-wire 4–20 mA pressure transducer; the module then provides two analog outputs, one for each monitored chamber, together with four pressure-limit digital outputs.

This is not a general-purpose analog input card. The hardware is tied to the RMS refiner-monitoring architecture, including its rack backplane and dedicated HPM signal connections (which is critical when replacing a field-worn card). The broader RMS-EX1 rack operates from +24 VDC ±10%, with a documented operating range of 0 to 55°C, storage range of -40 to +70°C, and IP00 protection.

Core Technical Specifications

The published documentation provides the functional I/O arrangement and system-level environmental specifications, but it does not provide a reliable standalone dimensional or weight specification for the card.

🚨 Global Compliance & Industry Certifications

• CE: The system documentation cites CE approval against EN 50081-2:1993, EN 50082-2:1995, and 89/336/EEC, with test report reference Enator TR976011. This is system-level evidence and should not be interpreted as a standalone certificate.
• UL / cUL: No standalone UL or cUL listing for was established in the documentation reviewed. Do not add a UL claim to the asset record without certificate evidence.
• ATEX / IECEx: No standalone hazardous-area certification was established for . The documentation reviewed specifies IP00, so the module should not be treated as a field-exposed hazardous-area device.
• Marine / DNV: No -specific marine approval was verified. A marine certification should only be recorded when the exact assembly and installation configuration are covered.
• EMC: The system’s historical CE/EMC reference is relevant when auditing the installed system, particularly where a replacement card is being introduced into an existing certified cabinet.

Audit requirement: Verify specific lot certifications with OEM. Preserve any declaration, test report, or certificate with the serialized asset record rather than relying on a generic product listing.

🚨 Long-Term Storage & Asset Preservation Guide

Keep the inside ESD shielding material. The module is a rack-mounted electronic assembly with PCB contacts and internal signal-conditioning circuitry. Do not store loose cards in ordinary plastic bags; maintain the original antistatic packaging where possible.

Control moisture even though the system manual permits broad humidity during operation. The documented humidity range is 15–95% non-condensing, while the rack itself is rated IP00. For warehouse storage, a practical target below 60% RH is preferable, with desiccant used when the card is sealed for long periods.

Avoid repeated thermal cycling. The published system storage range is -40 to +70°C, but stable indoor storage is preferable to moving the card between hot machinery areas and cold warehouses. Before installation, inspect connector contacts for oxidation and allow a cold-soaked module to reach cabinet ambient temperature before energization.

Physical Installation Prerequisites

Install the only in its compatible refiner-monitor rack architecture. The rack uses internal PCB connectors for its monitoring units and separate screw-terminal interfaces for external signals.

The rack itself is designed for mounting inside a protective cabinet and is grounded through the rack ground connection. Keep the cabinet dry and protected because the system-level IP00 rating provides no dust or water protection at the rack level.

No universal 50 mm clearance requirement could be verified specifically for . Do not invent a clearance value in an installation drawing; instead, preserve the manufacturer’s cabinet arrangement and allow enough space for connector access, card insertion, wiring bend radius, and cabinet heat removal.

Before removal, identify the A-chamber and B-chamber pressure connections. Label the four limit outputs and two analog outputs before disconnecting the cabinet wiring (this prevents a surprisingly common A/B channel reversal during maintenance).

Buyer’s FAQ — Logistics & Compliance Focus

Q1. What HS tariff code should be used for ?
There is no defensible universal HS code that can be assigned from VAL0122850 alone. Classification can depend on the importing country’s tariff schedule and whether customs treats the item as a dedicated measuring/control apparatus, a part of a measuring system, or another electrical instrument. Have the customs broker classify it against the technical description “Hydraulic Pressure Monitor, electronic industrial monitoring module” and retain the ruling or classification rationale in the shipment file.

Q2. Does the Country of Origin follow Metso because the part carries a Metso VAL number?
No. The VAL number identifies the Metso spare-part reference, while the accessible RMS documentation identifies the underlying hardware as Dametric equipment and maps to VAL0122850 and SKC9068256. The COO must be based on the actual manufacturing origin of the shipped unit, supported by supplier documentation and the physical nameplate where available.

Q3. Should shipping insurance cover the replacement-value exposure?
Yes, particularly for a legacy RMS installation. The module itself is relatively small, but a failed hydraulic-monitoring channel can delay refiner commissioning or force operation with reduced monitoring capability. Record the serial number, condition, packaging state, and pre-shipment photographs, then insure the shipment according to the documented replacement value.

Q4. Does include the latest firmware pre-loaded?
No standalone firmware package or upgrade process is identified in the accessible documentation. The module is described as a dedicated hydraulic-monitoring unit that processes two 4–20 mA pressure inputs and produces corresponding analog and limit outputs. Treat configuration and calibration as the engineering concern rather than assuming a firmware-flash step.

Q5. What should be included on the commercial invoice and packing list?
Use the complete identity: , Metso VAL0122850, SKC9068256, followed by a functional description such as “Hydraulic Pressure Monitor Module for RMS Refiner Monitor System.” Include quantity, unit value, COO, net/gross weight, package dimensions, and serial number where applicable. For audit-sensitive shipments, keep the supplier’s product identification and inspection record with the customs documentation.
