We typically use Hoffman and Rittal NEMA-12 or NEMA-4/4X enclosures. After we have met with the end user for engineering and project documentation review (ours or yours), we generate and authorize the BOM bill of materials and place orders to manufacturers and dealers.

PLCs, communication interfaces, operator panels, industrial computers, variable speed drives VFDs, standard and smart (DeviceNet, Profibus, ASi, Ethernet) motor control devices, power supplies, instrumentation and analyzers, to be installed in a control panel are carefully inspected and tested. Data sheets, user's manuals, wiring diagrams, manufacturer's recommended practices and specs are carefully considered for a trouble free and seamless integration.

We use industry standard components, control devices, robust terminal blocks and wiring systems from Siemens and Allen-Bradley. We follow color, gauge, wiring and protection NEC standards. Stainless steel bolts and screws, labels from Brady are used in all of our control panels. Besides a PLC and other major control devices, we include a control transformer and power supplies with semiconductor grade over current protection, MCR master control relay, thermomagnetic circuit breaker protected branch circuits, emergency stop wiring and buttons; every digital output is fuse-protected, 3 terminals for each analog channel, many more details.

We specialize in Smart MCCs Motor Control Centers and Networked control panels (Data Highway DH, DeviceNet, ControlNet, Industrial Ethernet TCP/IP, AS-i, Profibus, etc.), including wireless RF and Satellite links.

ControlSystemsUSA provides wireless networking solutions with applications in SCADA, telemetry, telecommunications and online transaction markets.


Just to give you a cost estimate, a control panel like the one shown above, is assembled, wired and tested in approximately 50 hours, including front door buttons.
