I/O modules

The GE DS200SLCCG1A DS200SLCCG1ABA handle network communication for GE Mark V turbine systems. These LAN communication control cards connect the turbine control to plant-wide networks. You can use either card for data exchange with host computers and HMIs. The units support multiple industrial protocols for flexible integration.

Communication and Network Specifications

The GE DS200SLCCG1A DS200SLCCG1ABA provide high-speed Ethernet connectivity for Mark V controllers. These LAN communication control cards auto-negotiate between 10 and 100 Mbps speeds. You can connect them to standard industrial Ethernet switches and routers. The units support Modbus TCP/IP for seamless plant integration.

Physical Dimensions and Weight

Each LAN communication control card weighs 0.34 kg for secure chassis mounting. The unit measures 235 mm long by 152 mm wide. Its PCB thickness reaches 1.6 mm with four internal copper layers. You can mount either card using four M4 screws through the designated holes.

Interface and Connection Points

One shielded RJ45 connector provides the Ethernet network interface. Two LED indicators show link status and network activity on the port. The GE DS200SLCCG1A DS200SLCCG1ABA include a 50-pin ribbon header for connection to the main controller. You will find a 4-pin power input connector for DC supplies. Additionally, six test points provide access for diagnostic measurements.

Energy Storage and Internal Circuitry

These LAN communication control cards store minimal energy for network buffering. Eight electrolytic capacitors provide 330 µF of total bulk storage. These capacitors filter power supply noise for the communication processor. The cards do not contain any battery for configuration retention. An onboard EEPROM stores MAC address and network settings permanently.

Component Layout and Construction

A dedicated 32-bit communication processor manages all network protocol tasks. The card includes an Ethernet PHY transceiver with auto-MDIX support. You will find 96 resistors, 62 capacitors, and 14 integrated circuits on the board. The GE DS200SLCCG1A DS200SLCCG1ABA include transformer isolation on the Ethernet port. A metal shield covers the processor section for electromagnetic interference reduction.

Variant Equivalence and Use

The GE DS200SLCCG1ABA represents a functional equivalent or later revision. Both versions share identical dimensions, connectors, and mounting hole locations. You can substitute one for the other without hardware modifications. Transitioning to these cards adds modern networking to legacy Mark V systems. Use GE DS200SLCCG1A DS200SLCCG1ABA for remote monitoring and data logging applications. For best results, use shielded Ethernet cables in industrial environments.
