MeloAuto-Trusted PLC & DCS Parts Supplier
The GE DS200SLCCG4A DS200SLCCG4ACC multi input PC control board provides versatile communication for Mark V systems. This board connects the turbine controller to multiple field devices and networks. You will find this control board in Speedtronic Mark V turbine cabinets. Its multi-port design supports simultaneous communication with various device types.
Multi-Input Architecture
This control board uses a 200 MHz 32-bit network processor. Consequently, it manages multiple communication protocols simultaneously. The GE DS200SLCCG4A DS200SLCCG4ACC provides two Ethernet ports and four serial channels. Moreover, onboard memory buffers data from all input sources. You can configure each port independently for different field devices.

Multi-Port Connectivity and Protocol Handling
The unit includes two auto-sensing Ethernet ports for network redundancy. Therefore, you can connect to plant networks and local HMIs simultaneously. This board replaces the DS200SLCCG4ACC version without any configuration changes. Simply remove the old board and install this one. GE designed this control board for hot-swappable installation. Hence, you can replace it without shutting down the turbine.
Eight PCB layers separate high-speed communication traces from power circuits. Seven connectors handle all Ethernet, serial, and power signals. The GE DS200SLCCG4A DS200SLCCG4ACC holds 2200 µF of capacitance for stable operation. Accordingly, it maintains connectivity during minor power fluctuations. Seven status LEDs show power, link, activity, and fault conditions clearly.
Serial Interface and Installation Guide
Four software-selectable serial ports support both RS-232 and RS-485 standards. You can connect PLCs, drives, and operator panels to this board. The GE DS200SLCCG4A DS200SLCCG4ACC works with all GE Mark V control systems. Always use shielded cable for serial connections longer than 15 meters. Proper termination of RS-485 networks prevents signal reflection errors.
The onboard processor handles multiple protocol conversions simultaneously. This offloads communication tasks from the main turbine controller. The GE DS200SLCCG4A DS200SLCCG4ACC delivers reliable multi-input control for turbine systems. Installation requires only a screwdriver for power and serial connections. This board operates in non-condensing environments with adequate ventilation.
