These two questions are often asked by design engineers, machine programmers, and safety personnel alike. Before we list our broad offering of these products, let us answer these two questions. What is a Panel Interface Connector? A panel interface connector (herein referred to as PIC) is a device that typically mounts to the outside of a control panel housing a PLC, computer, or other type of programmable device. Once in place, the PIC, which houses convenient
pass through connections, allows the user to interface with the computer, PLC, or other devices inside the control panel without opening the panel door. This in essence addresses the second question.
Why should I use a PIC?
The ability to interface with the contents of the cabinet without opening the door eliminates some potential safety hazards associated with having an open electrical panel. One of the main safety concerns is usually Arc Flash. An arc flash explosion is an extremely dangerous system malfunction that occurs when a short is created between electrified conductors.
This can happen when the conductors can no longer contain the applied voltage, or when the isolation between the conductors is breached. As a result, the air surrounding the short can ionize and create an intense “arc flash.” These explosions, with temperatures capable of exceeding 5000°F, have been know to cause severe burns and fatalities. In an effort to help protect individuals on the shop fl oor, the National Fire Protection Agency (NFPA) has written standards (NFPA 70E) that require protection boundaries, training, and clothing, for operators. Only properly trained personnel, with fi re-resistant suits, hoods, and gloves, with non-conductive tools, are allowed access to enclosures capable of producing an arc fl ash. The training, the equipment, and the time are all expensive. The use of a PIC eliminates the need to open the door, thus eliminating the need for extra training, equipment, and time.
A basic PIC typically contains a power outlet (single, duplex, or GFCI) along with one or more of the connectors
commonly used by the PLC, computer, or other programmable device within the control cabinet. These connectors include, but are not limited to, D-Subminiature (9, 15, 25, 37, or high density 15,) RJ45, RJ11, mini Din, BNC, USB, Ethernet, & Device Net. The above describes the content of a typical PIC, however, a PIC can be provided with almost any combination of connectors, those listed above plus others, and can come with or without a power outlet.
Currently there are over 2000 PIC designs in production. However, new ones are being created on a regular basis, so if you do see the layout you require please contact #800-966-2345 or sales@majorelectronix.com
