Each output point regulates 24 VDC power to field relays and solenoids, maintaining strict current limiting across shared commons (6 A maximum per common, 8 A total per module). The integrated optical isolation barrier attenuates high-frequency electrical noise and prevents ground potential loops from degrading control system signals.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Does the 621-2100R support hot-swapping during system operation?\u003c\/p\u003e\n\u003cp\u003eA: Yes, the module features hot-swappable rack mounting, allowing maintenance personnel to replace the module while the UCN chassis remains energized without interrupting backplane communications or adjacent channel operation.\u003c\/p\u003e\n\u003cp\u003eQ: What are the maximum continuous and surge current limits for individual channels on the 621-2100R?\u003c\/p\u003e\n\u003cp\u003eA: Each channel supports up to 2 A continuous load at 24 VDC, with non-repetitive surge handling up to 15 A for 2 AC cycles.
