Product Details
The CMA136 3DDE300416 is serial communication control module for ABB SYNPOL‑D generator excitation & protection systemstuckegrou....
This CMA136 module is connected via system cable C inside SYNPOL‑D rack, equipped with multiple DB9 serial ports, it undertakes communication data forwarding and signal conversion tasks for the whole protection systemstuckegrou.... It realizes data exchange between core logic board CMA131, local operation panel and remote upper‑level monitoring system.
It transmits generator real‑time operating parameters, fault alarm information and event log data to external monitoring devices, supports on‑site parameter debugging and status viewing.
Built‑in communication fault diagnosis function can identify serial port abnormality and link failure, and feed back fault status to main logic unit.
Compact DIN‑rail installation saves cabinet space, easy for maintenance and module replacement.
Conformal coated circuit board resists electromagnetic interference, adapts to complex electromagnetic environment of power plant control room.
Widely used in legacy SYNPOL‑D excitation‑protection system overhaul and renovation projects for thermal and hydropower generators.
It is important spare hardware for generator protection communication loop debugging and defective CMA136 module replacement.
