Core Technical Specifications

DS200RTBAG3A DS200RTBAG3AFB manages discrete I/O signals for GE Mark V turbine systems. This relay terminal board measures 30.5 cm in width and 25.4 cm in depth. The unit weighs approximately 1.1 kg without any attached cables. You will find 24 screw-type terminal blocks on this assembly. Each terminal accepts wires ranging from 12 to 22 AWG. The board includes 16 relay components in total. Four of these relays specifically handle high-current switching duties. For power needs, the board requires 28 V DC input. It draws roughly 250 mA under normal operating conditions.

Component Layout and Energy Storage

The PCB uses a four-layer design to ensure better signal isolation. Eight onboard LEDs show each relay’s status at a glance. DS200RTBAG3A DS200RTBAG3AFB features two 16-pin header connectors for backplane communication. Regarding energy storage, the board contains six electrolytic capacitors. Each capacitor stores 220 µF at 50 V. This configuration effectively filters out power supply noise. Consequently, the board tolerates input voltage ripple up to 5%. Three jumper switches let you configure each relay’s default state. The operating temperature range spans 0°C to 55°C. Meanwhile, humidity tolerance reaches 95% without any condensation.

Interface and Mechanical Details

Four mounting brackets securely hold the board to standard racks. DS200RTBAG3A DS200RTBAG3AFB offers 1500 V isolation between field and logic sides. Each relay supports switching up to 2 A at 30 V DC. Transitioning to physical protection, a conformal coating covers all traces. This coating effectively resists dust and moisture ingress. You can replace the board in under 15 minutes during routine maintenance.
