I/O modules

The DS200PANAH2A DS200PANAH2ADD manages ARCNET communication for GE LM gas turbine systems. This control board operates without a local area network connection. You can rely on it for standalone turbine monitoring and control tasks.

Key Technical Parameters

The table below lists all essential technical specifications for this ARCNET control board.

Physical Characteristics and Installation

This control board weighs approximately 0.45 kg for secure rack mounting. Its dimensions measure 260 mm x 75 mm x 25 mm for Mark V turbine racks. First, align the DS200PANAH2A DS200PANAH2ADD with the backplane slots. Then, press evenly until the board seats completely. Finally, tighten the top and bottom retaining screws. A conformal coating protects the board from harsh turbine environments.

ARCNET Communication and No-LAN Operation

The DS200PANAH2A DS200PANAH2ADD uses ARCNET protocol for deterministic data exchange. This board operates at a fixed rate of 2.5 Mbps for reliable communication. The No-LAN mode allows standalone control without external network connections. Consequently, this design suits remote turbine installations with limited infrastructure. The embedded microcontroller handles all protocol timing and error checking.

Component Layout and Board Variants

This board contains 6 integrated circuits for logic and communication functions. Twelve capacitors provide power filtering and signal conditioning. Eight resistors establish proper signal termination levels. The DS200PANAH2A DS200PANAH2ADD units share identical electrical specifications. The “ADD” suffix indicates a revised PCB layout or newer component revision. You can use either variant interchangeably in most LM turbine systems.
