GracePort and Grace Permanent Electrical Safety Devices (PESDs) drive innovation, enhance productivity and keep people safe and assets secure through simple and affordable solutions. GraceSense Predictive Maintenance System offers predictive maintenance capabilities and provide continuous monitoring and alert personnel when an unplanned shutdown is about to occur.


GracePorts® are Panel Interface Connectors, also known as Programming Ports, that typically mount on the exterior of Industrial Control Panels. The thru-door interface technology offered by the GracePort® provides users a safer and more productive method of programming PLCs and other devices within the control panel by bringing their component connections to the outside of the panel. We offer 16,000+ combinations of our Panel Interface Connectors. They are fully customized with a variety of components, domestic and international outlets, housing sizes, mounting options and enclosure types. We also offer personalization such as your company logo or custom text. If we don’t have a solution that meets your needs, we will built it.

Grace PESDs

Grace PESDs (Permanent Electrical Safety Devices) are fixed mounted safety devices that accomplish a variety of tasks including easy visual indication of voltage presence and satisfying industry requirements for absence of voltage testing.

Featured GRACEPORT® and PESDs

Voltage Test Station

The Voltage Test Station (VTS) combines our Safe-Test Point with a voltage indicator conveniently placed within a protective housing. The VTS test point jacks allow measurement of AC/DC voltages either phase to phase or phase to ground. The R-3W Series voltage indicators with either flashing or non-flashing LEDs visually represent the presence of voltage. Following facility safety procedures, insert the insulated meter probes with .080” tips into any two test point jacks to take a voltage reading with properly rated test equipment.

Voltage Indicators

Voltage Indicator PESDs are self-powered, UL listed, and permanently installed devices that visually represent the presence of voltage with flashing or non-flashing, redundant LED lights. Typically hardwired to the load side of an electrical feeder or a disconnect switch, voltage indicators illuminate whenever hazardous voltage is present in any individual phase. Voltage indicators greatly assist task qualified personnel with enhanced productivity and reduced risk while performing mechanical LOTO tasks by verifying energy presence.

Safe Test Point

A Safe-Test Point can be mounted on the side of an enclosure, door, or flange and provides four test point jacks to allow measurement of AC/DC voltages either phase to phase or phase to ground. By inserting insulated meter probes with .080” tips into any two test point jacks, you can take a voltage reading with your properly rated test equipment. Installation of a Safe-Test Points allows qualified personnel to perform absence of voltage tests from outside an electrical cabinet. By following proper safety procedures, the risks of an arc flash or shock hazard are significantly reduced.

The GracePort® Inside-Outlet® Panel Interface Connector, is typically mounted to the exterior of an Industrial Control Panel and has three GFCI protected receptacles, two outside and one inside the panel. This unique GFCI receptacle provides a trouble-free step toward NFPA 79 compliance which states all externally-mounted utility receptacles must be GFCI protected and tested every 30 days. Testing is now easy!

GracePort®+ is a UL listed large enclosure that is designed to provide protection for Human Machine Interface (HMIs) from dust, dirt, oil, water and other environmental contaminants found in industrial settings. They have a Formed-In-Place (FIP) polyurethane gasket to protect HMI equipment and other electronics, and they are UV rated, which make them well suited for outdoor applications. Use them as a stand-alone HMI cover or customize them with any of our GracePort® components.

Our suite of smart devices provide advanced analytics with deep insights about machine health to prevent unplanned downtime. Wireless condition monitoring solution capable of providing real-time, sensor-based insights to almost any industrial application. Advanced analytics provide asset managers with deep insights to machine health to effectively prioritize resources and maintenance spend. Improve overall plant reliability, safety, and maintenance metrics by remotely monitoring asset health. 


Wireless sensor nodes that monitor vibration and temperature to insightfully assess the health of rotating equipment.

Using advanced edge processing and IEEE 802.15.4 ZigBee compatible communication, these nodes enable plant floor personnel to continuously monitor equipment, detect defects, and predict health on any rotating equipment. 


The GraceSense™ Hot Spot Monitor (HSM) is a continuous, non-conductive temperature monitoring device that detects potential hot spots and alerts personnel of abnormalities in electrical equipment. Continuously monitor temperature in critical equipment real-time, for inaccessible locations with the doors closed. Providing maximum safety and protection for personnel and identify equipment failures before they occur to avoid unplanned downtime and equipment failures. Integrate the Hot Spot Monitor with a panel-mount node to remotely monitor in the browser-based Maintenance Hub or via MODBUS TCP/IP or EtherNet IP into your existing SCADA system.
