HMI Enclosure Accessories
The accessories for HMI enclosures are vital to the setups that integrate these command and control panels. If the user requires a specific type of command access to an HMI, then a setup where the HMI is housed inline with the HMI enclosure is a specific command panel solution. The HMI enclosures come with a variety of accessories or can be upgraded with accessories for aesthetic appeal, durability in specific environments, and even certain hardware integrations that can allow the use of a touchscreen in an HMI setup under certain conditions.
Easy assembly and secure location are the objectives in the installation of HMI devices. Secure placement of HMI devices along with the mounting mechanism that delivers easy access to the HMI is an integral part of HMI device design. Mounting options for HMI devices include direct surface mounting, wall mounting, and even through-panel mounting, which essentially allows the HMI to be integrated into the surface of a panel. In cases where a clear view into the enclosure is required, a window can be integrated into the door of the HMI enclosure. A keyboard is a commonly sought-after accessory for HMI enclosures.

HMI vs OIT, What's the Difference?
Human Machine Interface (HMI) is a software interface that allows operators to interact with various pieces of electrical hardware and controls systems. HMI typically utilizes monitors or screens to display information, which are referred to as HMI screens. The screens are not the actual HMI, but are a tool used to display HMI software. For example, electrical enclosures often have screens mounted on the outside of them to provide users with information about ongoing process and to allow users to make changes to the system.
Operator Interface Terminal (OIT) typically displays basic information about the electrical hardware that it is attached to. It provides only local information about the environment it is interfacing with and allows control and monitoring for that one piece of hardware, not an entire system.
