Core Technical Specifications

DS200RTBAG1A DS200RTBAG1ABB manages discrete I/O signals for GE Mark V turbine control systems. This relay terminal board measures 28.0 cm in width and 24.5 cm in depth. The unit weighs approximately 0.95 kg without any attached cables. You will find 16 screw-type terminal blocks on this assembly. Each terminal accepts wires ranging from 14 to 22 AWG. The board includes 8 relay components in total. Two of these relays specifically handle high-current switching duties. For power input, the board requires 24 V DC. It draws roughly 150 mA under normal operating conditions.

Component Layout and Energy Storage

The PCB uses a dual-layer design for reliable signal routing. Four onboard LEDs show each relay’s current status at a glance. DS200RTBAG1A DS200RTBAG1ABB features one 16-pin header connector for backplane communication. Regarding energy storage, the board contains three electrolytic capacitors. Each capacitor stores 220 µF at 35 V. This configuration effectively smooths out power supply noise. Accordingly, the board tolerates input voltage ripple up to 5%. One jumper switch lets you configure the relay default state. The operating temperature range spans 0°C to 50°C. Meanwhile, humidity tolerance reaches 90% without any condensation forming.

Interface and Mechanical Details

Two mounting brackets securely hold the board to standard racks. DS200RTBAG1A DS200RTBAG1ABB offers 1000 V isolation between field and logic sides. Each relay supports switching up to 1.5 A at 24 V DC. Transitioning to physical protection, a conformal coating covers all copper traces. This coating effectively resists dust and moisture ingress. You can replace the board in under 10 minutes during routine maintenance.
