Built‑in function

62HD‑4EJ6‑0H single‑loop PI controller receives 4‑20mA process variable signal from field transmitters and executes closed‑loop regulation. It supports local set‑point modification and bumpless auto‑manual switching to prevent output shock during mode change. Metal shield housing suppresses electromagnetic interference,stable for pressure,flow and temperature control loops in petrochemical and chemical plants.
