HMI & Displays

Human-Machine Interfaces (HMIs) are how your operator sees machine state, alarms, recipes and diagnostics. Modern industrial HMIs are essentially purpose-built Linux or RTOS tablets with capacitive or resistive touch, a hardened front, IP65/66-rated bezel, and a fieldbus interface speaking the controller's native protocol. Sizes range from 4-inch keypad units beside a single VFD up to 22-inch panels driving a full SCADA view.

Teach pendants are a specialised cousin — handheld programming devices for industrial robots and CNC machines, with an enable switch and emergency-stop required by ISO 10218 / IEC 60204. CNC displays cover the LCD panels and monitor units used on FANUC, Mitsubishi M-series, and similar machine tool controllers, where exact replacement (model, backlight, connector pinout) matters more than equivalent functionality.

When specifying a new HMI, think about three things first: screen size and orientation (suited to your operator's distance and content density), the protocol stack you need to talk to controllers and peripherals, and how the panel will be mounted and sealed. We carry HMIs from the major automation vendors and can supply both new panels for new builds and direct replacements for failed units on existing machines.
