Working Principle: After‑24 VDC‑power‑supply‑energizes‑5501‑365‑REV‑C‑module,‑hardware‑initialization‑and‑self‑diagnosis‑routine‑executes. Field‑sensor‑analog‑input‑signals‑pass‑through‑on‑board‑signal‑conditioning‑circuits‑and‑convert‑into‑digital‑measurement‑data‑via‑analog‑to‑digital‑converter. Digital‑measurement‑data‑transmits‑to‑MicroNet‑main‑controller‑through‑chassis‑backplane‑bus. Main‑controller‑computes‑control‑output‑set‑points‑according‑to‑turbine‑governor‑control‑logic‑and‑sends‑digital‑commands‑back‑to‑5501‑365‑REV‑C‑module. Module‑internal‑digital‑to‑analog‑converters‑transform‑digital‑set‑points‑into‑analog‑output‑signals‑which‑drive‑field‑turbine‑actuators‑and‑valve‑positioners.
