Core Technical Specifications

DS200RTBAG2A DS200RTBAG2AGC handles discrete I/O interfacing for GE Mark V turbine controls. This relay terminal board measures 30.5 cm wide and 25.4 cm deep. The unit weighs approximately 1.05 kg without cables. You will find 20 screw-type terminal blocks on this assembly. Each terminal accepts wires from 12 to 22 AWG. The board includes 12 relay components in total. Three of these relays specifically manage high-current switching paths. For power input, the board requires 28 V DC. It draws roughly 200 mA during normal operation.

Component Layout and Energy Storage

The PCB uses a four-layer design for reliable signal separation. Six onboard LEDs indicate each relay’s current status. DS200RTBAG2A DS200RTBAG2AGC provides two 16-pin header connectors for backplane links. Regarding energy storage, the board contains four electrolytic capacitors. Each capacitor stores 330 µF at 50 V. This setup effectively smooths out power supply fluctuations. Accordingly, the board tolerates input voltage ripple up to 4%. Two jumper switches let you configure relay default positions. The operating temperature range runs from 0°C to 55°C. Meanwhile, humidity tolerance reaches 95% without condensation forming.

Interface and Mechanical Details

Four mounting brackets lock the board securely into standard racks. DS200RTBAG2A DS200RTBAG2AGC offers 1500 V isolation between field and logic circuits. Each relay supports switching up to 2 A at 30 V DC. Transitioning to physical protection, a conformal coating covers all copper traces. This coating resists dust and moisture effectively. You can replace the board in under 15 minutes during scheduled maintenance.
