1.Main Functions

Serves as core logic processing board for Sulzer legacy turbine / compressor control rack, executes closed‑loop regulation, sequence logic and interlock protection for rotating‑machinery equipment.
Communicates with other I/O boards via back‑plane bus, collects field sensor signals including speed, pressure, vibration and temperature; distributes control commands to drive peripheral modules.
On‑board integrated EPROM / RAM memory stores system configuration parameters, operating set‑points, runtime data and fault event logs.
Provides multi‑channel galvanic‑isolated digital input & output channels for equipment interlock, alarm triggering and external actuator driving.
Built‑in hardware self‑diagnosis function, detects board hardware failure, bus communication errors and channel abnormal status, outputs fault indication via front‑panel LED indicators.
Designed for rack plug‑in installation; operates under industrial cabinet temperature range 0 ℃ ~ +60 ℃, meets EMC anti‑interference requirements for heavy‑duty industrial sites.
Supports real‑time safety interlock logic to realize emergency trip protection for turbines and compressors upon abnormal working conditions.

Sulzer RM41 Control Board

Sulzer RM41 Control Board

Applied in legacy Sulzer turbomachinery control systems for steam turbines, gas turbines and centrifugal compressors in petrochemical, oil‑gas and power‑generation plants.
Responsible for equipment sequence control, safety interlock protection and signal interaction inside the control cabinet.
Used exclusively as maintenance spare‑part for existing running Sulzer equipment; this model is factory‑obsolete and not applicable for new‑project deployment.
Cannot work independently. It must be inserted into the matched Sulzer system rack, cooperating with power‑supply unit and other I/O interface boards to achieve full control functions.
Transmits operating data and alarm signals to upper‑level DCS / PLC system for remote monitoring.
