Yes, in two areas. Adgo builds HMIs as a UL 508A- and UL 698A-certified panel. UL 508A is the standard for constructing general-use industrial control panels, and the label applies to a given panel when the specification calls for a third-party listing mark. UL 508A panel certification governs how the panel is built:
- General-use panels rated 1000 volts or less in ordinary locations are governed by UL508A. Also, the HMI, PLC, breakers and terminal blocks carry their own recognized ratings before assembly.
- Short-circuit current rating (SCCR) is calculated and marked on the panel, which UL 508A and NEC Article 409 both require pre-install.
- Operator-interface devices such as pushbuttons, pilot lights and selector switches are wired to construction rules alongside the HMI.
If an inspector requires a third-party mark, then a panel built to UL 508A carries the listing label that satisfies the AHJ (authority having jurisdiction). We build every HMI control panel to UL 508A as a certified panel shop, with a listing applied when the spec calls for one. See the same build standards on our Electrical Control Panels page.
