Technical FAQ
What types of loads can the ARM55C control?
The dry contact outputs are suitable for solenoid valves, motor starters, annunciators, and interposing relays, where galvanic isolation is required.
Does the ARM55C support redundant power supplies?
Yes. The board is compatible with dual-redundant power configurations to maintain output availability during a single power source failure.
How does the ARM55C manage high wiring density?
The use of M3.5 screw terminals provides secure wiring while accommodating high channel density and resisting vibration common in industrial environments.
