A process control panel houses the controls, instrumentation, and safety equipment that keep an automated system running. Its design must match the specific process, field instrumentation, and operating environment of the facility.

Panel-Fab’s custom electrical control panels for the process control industry are built for your specifications. We work from your drawings, BOM, and system architecture to determine the panel layout, components, wiring, and enclosure specs without relying on pre-set configurations.

The Role of Control Panels in Process Control

Industrial process control panels must handle complex input/output (I/O), field instrumentation, and integration with supervisory and safety systems. Poor panel design leads to wiring errors, thermal management issues, and documentation gaps that delay commissioning and increase operational risk.

The primary benefits of customized control panels in process control applications are maximized fit and long-term reliability. A panel built to your exact specifications means:

Optimized footprint: Ensures correct component sizing and layout for your thermal and spatial constraints.
Matched wiring: Aligns directly with field instrument loop diagrams for efficient field installation.
Accurate documentation: Delivers as-built schematics that reflect actual panel construction.
Streamlined commissioning: Reduces startup delays and lowers long-term maintenance overhead.

Off-the-shelf panels can fail to meet the specific signal routing and safety requirements that process control environments demand.

Systems We Support

We build panels across a full range of process automation and safety architectures.

SIS, DCS, and SCADA Integration

We build panels for Safety Instrumented Systems (SIS), Distributed Control Systems (DCS), and SCADA architectures. Each system type has distinct wiring and segregation requirements, and we design to those distinctions from the start, including SIL-appropriate component ratings for SIS applications.

DCS and SCADA panels are built to handle high-density I/O, marshalling, and terminal strip layouts matched to your control system architecture. We work from your system vendor’s loop drawings and interface specifications, not from generic templates.

Valve Manifold and Instrumentation Panels

We fabricate valve manifold panels and instrumentation panels for field-mounted and control room applications. These panels manage pneumatic and electrical signal routing to pressure transmitters, flow meters, temperature instruments, and final control elements.

Our pneumatic control panels are built with the same precision as our electrical assemblies: correctly labeled, routed, and tested before shipment.

Meeting UL 508A and Functional Safety Standards

All panels we build for industrial process control applications meet UL 508A, the standard for industrial control panels. UL 508A compliance covers component ratings, wiring methods, spacing, and short-circuit current ratings (SCCR). These requirements are commonly enforced for facility safety and insurability.

For applications requiring functional safety compliance, we build to support ISA-84 / IEC 61511 standards through circuit segregation, SIL-rated hardware selection, and structured documentation packages. We also build panels to UL 698A, CE, ETL, VDE, ESA, and military specifications as project scopes require.

How Panel-Fab Fabricates Panels for Process Control

Our fabrication process is consistent and repeatable across project sizes. Here is how a typical process control panel moves through our facility:

Design review. We review your drawings and BOM before any fabrication begins. Wiring diagrams, layout drawings, and component specifications are reconciled upfront to prevent rework downstream.
Enclosure preparation. Cutouts are machined using our Steinhauer equipment. Painting and engraving are handled in-house.
Component mounting and wiring. Components are mounted to the approved layout and wired point-to-point, with correct torque and labeling throughout.
Testing. Every panel is functionally tested against the original drawings before it leaves our facility. Nothing ships without passing verification.

We operate two shifts across six facilities with more than 100,000 square feet of workspace. Standard lead times run 4 to 6 weeks, depending on project size and parts availability. See a full breakdown of our process on the panel building page.

Custom Engineering, Documentation, and Testing

Every Panel-Fab project is managed by a single point of contact from kickoff through delivery. You are not passed between departments or left chasing updates.

For process control projects, documentation feeds directly into your HAZOP, your safety case, or your facility’s inspection records.
