Support for legacy and current systems
Where we support
Automation parts for demanding oil and gas environments.
Oil and gas sites often combine long-service equipment with newer control platforms. Our focus is helping maintenance and procurement teams identify compatible replacement parts by complete model number.
Process Control
PLC, DCS, controller and I/O modules used for continuous process and utility control.
Safety Systems
Safety PLC, ESD, SIS and critical I/O components for shutdown and interlock functions.
Remote I/O & Networks
Communication, interface and remote I/O hardware connecting field devices to control rooms.
Drives & Power
Drive, power-supply and cabinet components supporting pumps, fans and auxiliary systems.
Industry knowledge
Where industrial automation spare parts fit in the oil and gas value chain.
The same replacement part can support very different operating risks depending on where it is installed. Understanding the application helps maintenance teams choose the right automation component and avoid compatibility problems.
Upstream production
At wellheads, gathering stations and production facilities, automation equipment monitors pressure, flow, temperature and rotating machinery in remote or harsh environments.
- Remote I/O and communication modules collect field signals.
- Pressure, flow and level inputs support process visibility.
- Vibration monitoring helps protect pumps and compressors.
Midstream pipelines & compression
Pipeline stations and compressor packages depend on continuous control, reliable communications and fast protective actions to keep product moving safely.
- PLC and DCS modules control packaged equipment.
- ESD and safety I/O support emergency shutdown logic.
- Proximity probes and overspeed systems protect compressors.
Refining & petrochemical
Refineries run complex continuous processes where a failed controller, I/O module or safety device can affect an entire production unit.
- DCS hardware maintains stable process control.
- SIS, burner-management and interlock systems reduce risk.
- HMI, network and power components support operators.
Maintenance insight: Oil and gas facilities frequently operate legacy automation systems for many years. For an urgent replacement, confirm the complete part number, revision, system family, environmental rating and installed application before ordering.
Evidence & technical resources
Real applications and public technical documentation.
Use the links below as technical reference points when evaluating machinery monitoring and hazardous-area requirements. Product configuration and certification must always be checked against the exact order code.
Gas processing compressor: rising bearing vibration
Baker Hughes describes a gas-processing compressor case where increasing bearing vibration crossed the trip limit. Diagnostic review was used to investigate the machine condition before further damage.
Application takeaway: vibration monitoring data can support maintenance decisions for critical compressor trains.
Read the public case study →Refinery reciprocating compressor: early fault detection
In a published NATREF refinery case, Bently Nevada monitoring was used on a reciprocating compressor to identify abnormal crosshead vibration and help locate a valve/unloader issue.
Application takeaway: sensor location and monitored parameter should match the compressor failure mode.
Read the public case study →Public hazardous-area references
These documents show the type of certification information engineers should review: ATEX/IECEx marking, zone, temperature class, installation conditions and compatible barriers or isolators.
3500 regulatory and technical resources →How to use certification documents
Do not treat a general product-family approval as approval for every variant. Match the complete model, each option, barrier/isolator arrangement, area classification and local project requirements.

Replacement part buyer guide
How to choose the right oil and gas automation spare part.
Use these checks before ordering a PLC module, DCS card, safety component or vibration-monitoring part for an operating facility.
Match the complete part number
Compare the full order code, suffix, revision and connector type—not only the product family name.
Confirm the installed system
Identify whether the part belongs to a Bently Nevada monitoring rack, Honeywell DCS, ABB PLC, Emerson DeltaV or another platform.
Check the application and environment
For hazardous areas or rotating equipment, confirm certification, signal type, temperature range and required protection function.
Send the BOM or nameplate photo
A clear photo helps reduce wrong-part risk and allows our team to check availability, condition and lead time.
Can legacy automation parts still be sourced?
Many oil and gas sites continue to operate long-service control systems. Exact-model sourcing may be possible for surplus, discontinued or hard-to-find parts, subject to availability and verification.
What information should I include in an RFQ?
Send the full model number, quantity, required condition, installed system, destination and any nameplate or connector photos available.
Can one order include several brands?
Yes. A single requirement can include monitoring, PLC, DCS, HMI, drive, power and safety components from several manufacturers.
Oil, gas & gasification Q&A
Questions maintenance and project teams ask before ordering.
RefineryGas processingGasificationCompressor stationTurnaround maintenance
These questions are written for engineers, EPC contractors and local trading companies supporting oil, gas and gasification facilities.
Which automation parts are commonly needed in a refinery or gasification plant?
Typical requirements include DCS and PLC modules, remote I/O, communication cards, power supplies, HMI components, safety I/O, ESD/SIS parts and vibration-monitoring equipment for compressors, pumps, turbines and other rotating machinery.
What should we check when replacing a module in a DCS or PLC system?
Confirm the complete part number, hardware revision, firmware compatibility, rack or backplane type, I/O signal requirements, connector arrangement and the installed system architecture.
Why are vibration monitoring parts important for compressors and turbines?
They provide information about shaft vibration, position, speed and machine condition so maintenance teams can recognise abnormal behaviour and protect critical rotating assets.
Can you help with ESD, SIS or gas safety system spare parts?
Yes. Send the complete model and installed platform details. Safety-related components must be checked carefully against the approved system design and project documentation.
What if the required part is obsolete during a turnaround?
We can review the exact legacy model, possible compatible revisions and available sourcing options. Any replacement or migration decision must be approved by the site engineering team.
What documents do EPC contractors usually need?
Requirements often include a quotation, model confirmation, datasheet or manufacturer reference, unit condition, lead time, packing information and available compliance documentation.
Can a local trader send a multi-brand requirement for one gas project?
Yes. Multi-brand BOMs are welcome and can include control, monitoring, safety, communication, HMI, drive and power components.
What information helps us quote quickly?
Provide the complete model number, quantity, condition preference, destination, required delivery date and clear photos of the nameplate or installed part.
