Model Relationship:  

0552N1QLG132A-01 = Product Model (Firmware Version V1.0)  

853-172404-101 = GE Original Manufacturer Part Number; both refer to the same industrial communication board.  

I. Product Overview  

The GE Intelligent Platforms Industrial Communication Interface Module / Gateway Card is an I/O communication sub-card designed for use in GE gas turbine and power plant DCS systems, specifically for MARK VI control systems. It serves as a data relay between the main CPU and field I/O devices, sensors, and valve actuators. This board is a standard spare part used in thermal power plants and gas turbine units.  

Origin: Germany / USA original manufacturing.

Key Electrical Specifications  

Power Supply: DC 24V, rated operating current 3.4A, total power consumption < 2W  

Communication Interfaces: RS485, CAN, Ethernet port; supports Modbus RTU/TCP and proprietary gas turbine bus protocols  

Operating Environment  

Operating Temperature: -20°C to +55°C; Storage: -40°C to +85°C  

Protection: Industrial-grade PCB card, installed on cabinet rails  

Dimensions / Weight  

Size: Approx. 170 × 100 × 25 mm; Net weight ≈ 0.28–0.6 kg (varies by original factory batch)

Functional Description  

Signal Zones: The board features two primary signal zones  

Reset + Fault Alarm Zone: Monitors module faults, hardware resets, and system interlock alarm signals  

Command Code Zone: Transmits control commands from the CPU and provides feedback on field device operational status  

Function: Enables data exchange between the main CPU and remote I/O modules and field instruments (pressure/temperature transmitters, solenoid valves, actuators). Serves as a core board for gas turbine start-stop interlocks, speed, and temperature parameter acquisition and transmission.

Application Scenarios  

GE heavy-duty gas turbines and steam turbine MARK VI / MARK VIe control systems  

Refinery captive power stations and coal chemical power workshops using DCS control systems  

Remote I/O communication expansion in large-scale PLC systems
