DS215SLCCG1AZZ01B GE LAN Communication Board

Description

The DS215SLCCG1AZZ01B is a GE LAN Communications Card within the Mark V control system. It features isolated and non-isolated communication circuits with drives or exciters. The card connects to a 16-position alphanumeric display and integrates a LAN Control Processor (U1) as its main microprocessor. Two replaceable EPROMs (U6 and U7) house the LCP software, while U8 and U9 provide LCP-specific memory. Communication with the Drive Control Processor occurs through dual-ported RAM (U5), allowing concurrent access by multiple processors. The card's triple modular redundant (TMR) design enhances reliability, enabling continued operation and maintenance without turbine shutdown in case of processor failures.

Board Connections

2PL Connector: Connects ±5, 15, and 24 V dc I/O signals between components like the Power Supply/Interface Board and Drive Control Card, facilitating power and signal exchange.

3PL Connector: Connects inputs from the Drive Control Card to the SLCC, enabling effective communication and coordination for control functions.

10PL Connector: Interfaces I/O signals between the LAN I/O Terminal Board and the LAN Card, supporting data exchange and remote monitoring capabilities within the network.

Application Data

Berg-type Hardware Jumpers (JP): These physical connectors allow for manual adjustment to establish or break connections on the device, providing a standardized labeling system for easy identification.

Wire Jumpers (WJ): These physical wires create connections between specific points, offering flexibility in configuring the device's circuitry and ensuring proper functionality for various applications.
