FAQ
Q Why 24 VDC?
A
International standard (IEC 61131-2, EN 60204-1) — low shock risk, battery-backable, universal sensor voltage. AC in cabinets only for servos and heaters.
Q Redundant N+1 supply?
A
Two independent AC inputs + two power supplies + redundancy module (Phoenix Contact REL) — fail-safe. Mandatory in critical cabinets (hospital, process).
Q UPS?
A
24-VDC UPS in cabinet (Phoenix Contact UPS-CP, Siemens SITOP UPS) with 20-40 Ah battery for graceful controller shutdown; server UPS (APC, Eaton) is separate.
