Beijer Electronics MAC 50/ML Operator Panel HMI Terminal | Type 00920A 24VDC

Beijer Electronics MAC 50/ML Legacy Industrial HMI Operator Panel

Keep your mission-critical vessel control configurations and automated lines operating smoothly with the Beijer Electronics MAC 50/ML Operator Terminal. Engineered in Sweden to handle continuous runtime cycles in high-vibration engine rooms and industrial plant installations, this robust textual display panel provides smooth process monitoring and variable parameter adjustments over older, highly stable automation busses.

The front layout houses an industrial-grade membrane keypad with specialized quick-action hotkeys designed for instant alarm auditing, local control diagnostics, and menu navigation arrays (MAIN MENU, direction arrows).

The rear configuration enclosure is outfitted with hard-wearing communication channels and hardware overrides:

• Dual Protocol Support: Standard DB25 layout for multi-node differential RS-422 communication loops alongside a standard DB9 interface for RS-232 localized laptop programming or printer logs.

• Mode Toggle Switch: Mechanical slider switch to quickly shift operational states between system programming upload runs (PROG) and active execution cycles (RUN).

• Memory Integrity: Features an internal Lithium memory backup battery bay to prevent critical screen parameters or data logs from dropping during sudden factory blackouts.
