Automation Control Panels
Custom PLC and HMI control panels engineered for process automation, machine control, and industrial monitoring. Built to UL 508A with full documentation packages for commissioning and maintenance.
Custom Automation from Engineering to Commissioning
Our automation control panels are engineered from the I/O list up — PLC program, HMI screen development, field wiring, and site commissioning are all in scope. We work with Rockwell Allen-Bradley, Siemens, Schneider, and other major platforms.
- PLC programming: Allen-Bradley (Studio 5000), Siemens (TIA Portal), Schneider (EcoStruxure)
- HMI screen development with alarm management and trending
- I/O list, control narrative, and functional description included
- UL 508A listed panel with UL labelled components
- NEMA 12 (standard indoor) or NEMA 4X (washdown / outdoor)
- Full shop acceptance testing before shipment
What's Included
- PLC rack with CPU, power supply, and I/O modules
- HMI touchscreen (7"–21") mounted or remote-mount option
- Ethernet switch for plant network integration
- UL 508A listed panel — NFPA 79 compliant wiring
- Terminal block wiring with ferrule-terminated field connections
- Main disconnect and branch protection per NEC/CEC
- Control power transformer (CPT) with fused secondary
- Door-mounted operator interface (pushbuttons, pilot lights)
- Structured wiring: power in conduit duct, signals in separate duct
- +Redundant PLC CPU configuration for critical processes
- +Remote I/O rack at field equipment (distributed I/O)
- +UPS (24 VDC or 120 VAC) for power failure ride-through
- +Ethernet/IP to Modbus TCP gateway
- +Cellular or fibre modem for remote access (VPN)
- +Vision inspection camera integration
- +SCADA host software and historian integration
- +Witnessed factory acceptance testing (FAT) with client

Common Questions
Both options are available. We can write the full PLC program from your control narrative and P&ID (functional design specification), or we can wire and test a panel using your supplied PLC program. We can also support existing programs with modifications and testing.
UL 508A is the North American standard for industrial control panels. A UL 508A listed panel has been inspected and tested by a nationally recognized testing laboratory (NRTL) and meets the component and wiring requirements of the standard. Most jurisdictions in the U.S. and Canada require this listing for industrial control panels.
Yes — commissioning support is available and typically includes loop testing, I/O check-out, PLC sequence verification, and operator training. We can provide commissioning services at any site in Canada or the United States.
