Product Brief:

AH116‑2 is legacy plug‑in interface board for ALSTOM Alspa turbine control rack. It acquires temperature,pressure,speed and other field sensor signals,performs signal conditioning and filtering,then transmits valid data to main controller through backplane bus. Meanwhile,it outputs control drive signals to on‑site actuators to realize auxiliary closed‑loop control for turbine unit. Panel LED indicators support quick on‑site fault checking without extra testing tools. Plug‑in cabinet mounting structure enables convenient disassembly and module replacement. This is EOL discontinued spare part,widely used for thermal power plant steam turbine control system maintenance and renovation. Please confirm hardware revision,rack compatibility and signal configuration before purchase. Strict ESD anti‑static protection must be followed during installation.
