Product Brief:

15A0026H08 is upgraded‑revision safety function module of Emerson Ovation DCS system, succeeding 15A0026H06. It undertakes safety‑related signal collection, logic voting and interlock output for boiler, turbine and other critical equipment in thermal power plants. Compared with H06 version, it optimizes hardware circuit, strengthens channel fault identification and signal filtering capability, adapts to harsh electromagnetic field environment on site. It monitors safety‑loop working state in real‑time and triggers protective interlock under abnormal 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 status 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 matching before purchase. Strict ESD anti‑static protection shall be followed during installation and replacement
