Product Brief:

AM164 is legacy plug‑in analog output module for ALSTOM Alspa 3300‑50 control rack,mainly used in steam turbine governor system. It converts digital control commands from main controller into standard analog 4‑20mA or 0‑10V signals to drive hydraulic actuators,valve positioners and field regulating equipment. Each channel features galvanic isolation to suppress field interference and improve control stability. It receives configuration data and power supply through rack backplane bus. Front‑panel LED indicators support quick on‑site channel fault diagnosis 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 turbine governor system maintenance and renovation. Please confirm hardware revision,signal range configuration and rack compatibility before purchase. Strict ESD anti‑static protection shall be performed during installation.
