Product Brief:

15A0026H10 is the latest‑revision safety function module of Emerson Ovation DCS system, succeeding 15A0026H06 and 15A0026H08. It is responsible for safety‑signal acquisition, logic voting and interlock output for critical equipment such as boilers and turbines in thermal power plants. It further optimizes safety‑logic arithmetic algorithm and multi‑layer channel fault diagnosis mechanism, strengthens signal filtering and anti‑interference performance for complex field electromagnetic environment, adds fault‑record storage and graded safety‑abnormality alarm function. It monitors safety‑loop operating status in real‑time and triggers protective interlock quickly under abnormal working conditions. It supports hot‑swap, online module replacement without cutting off system power supply. Multi‑group LED indicators intuitively display power‑on, operation, safety‑channel and fault information for convenient on‑site inspection and rapid fault location. This is EOL discontinued spare part,widely used for maintenance and renovation of thermal power plant Ovation DCS system. Please confirm hardware revision and controller firmware version before purchase. Strict ESD anti‑static protection shall be followed during installation and replacement。
