Product Brief:

15A0026H27 is the late‑generation safety function module of Emerson Ovation SIS safety I/O series, iterated on the basis of 15A0026H13. It completes safety‑signal collection, logic voting and interlock output for critical equipment such as boilers and turbines in thermal power plants. It optimizes hardware surge‑immunity circuit design, improves anti‑interference performance under severe electromagnetic interference site conditions, further upgrades channel fault‑diagnosis accuracy and fault‑event recording stability. The module monitors safety‑loop operating status in real‑time and triggers fast protective interlock under abnormal working conditions. It supports hot‑swap for 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.
