DS200RTBAG1A GE

Key Technical Parameters

Advantages & Core Features

• Remote termination capability – The DS200RTBAG1A is designed to be installed in remote junction boxes or marshalling cabinets, consolidating field wiring from sensors, actuators, and other field devices located at a distance from the main control rack.

• High-density 64-terminal capacity – Provides 64 terminals (4x 16-terminal blocks) for field wiring, consolidating a large number of I/O connections onto a single board.

• Multi-signal type support – Supports analog inputs (4-20mA, 0-10V), digital inputs (24-125 VDC), digital outputs (relay/transistor), thermocouple, and RTD connections.

• Individual channel fusing – Each output channel is protected by a user-replaceable fuse, preventing field wiring faults from damaging the board or backplane.

• Channel status LEDs – 16 LEDs provide immediate visual indication of output channel status (green = active, red = fault/overload), simplifying troubleshooting in remote locations.

• Screw-clamp terminals – Rise-clamp screw terminals with dual-wire entry provide secure, reliable connections for 12-22 AWG solid or stranded wire.

• Galvanic isolation – 2,500 VAC isolation protects the Mark V backplane and processor from field-side voltage spikes and ground loops.

• Compact 1-slot form factor – Occupies a single slot in the remote junction box or main rack.

Application Cases

• Distributed steam turbine control – A chemical plant uses the DS200RTBAG1A in a remote marshalling cabinet located near the steam turbine, consolidating 32 analog inputs and 16 digital outputs from field sensors, with a multi-conductor cable connecting back to the main Mark V rack in the control room.

• Offshore platform with distributed I/O – A North Sea platform uses the DS200RTBAG1A in remote junction boxes located near compressors and pumps, reducing the length of individual field wiring runs.

• Gas turbine with remote auxiliary systems – A combined-cycle plant uses the DS200RTBAG1A to terminate I/O from auxiliary systems (lube oil, cooling water) located at a distance from the main turbine control rack.

• Hydroelectric plant with distributed architecture – A dam facility uses the DS200RTBAG1A in remote cabinets near the turbine hall, consolidating I/O from multiple turbine auxiliary systems.

Comparison with Related Variants

Selection Suggestions

1. Assess distribution requirements – Select the DS200RTBAG1A if your field devices are located at a distance from the main Mark V rack and you need to consolidate wiring in a remote location.

2. Count your I/O terminations – The DS200RTBAG1A supports up to 64 terminals. Ensure this is sufficient for your remote I/O requirements.

3. Confirm signal types – Ensure the board supports the required field signal types (analog, digital, thermocouple, RTD).

4. Verify communication interface – Ensure the board’s backplane or multi-conductor cable interface is compatible with your Mark V rack configuration.

5. Verify fuse ratings – Ensure that the fuse ratings on the board match your output channel current requirements.

6. Assess environmental conditions – The DS200RTBAG1A has no conformal coating. For harsh environments, consider the coated DS200RTBAG1ADC variant or use external protective measures.

7. Procurement – The DS200RTBAG1A is rare. Purchase from reputable suppliers offering functional testing (channel verification, fuse testing, LED testing). Lead times: 6-10 weeks.

Important Precautions

• Power down completely – De-energize the entire system before inserting or removing the DS200RTBAG1A. Hot-swapping is not supported.

• ESD protection – Use wrist strap and anti-static mat.

• Wiring termination – Ensure field wires are properly stripped and securely clamped. Use appropriate wire gauge (12-22 AWG).

• Fuse replacement – Replace fuses only with specified types and ratings.

• Cable routing – Ensure multi-conductor cables are properly shielded and routed away from high-voltage cables to avoid noise coupling.

• Signal segregation – Route analog and digital signals separately to avoid noise coupling.

• Cleaning – Use compressed air only (max 50 PSI). No liquids.

• Storage – Store at 10-30°C, 20-50% RH.

Final Expert Recommendation

The DS200RTBAG1A is a remote terminal board designed for Mark V installations with distributed control architectures, where field devices are located at a distance from the main control rack. Its 64-terminal capacity, individual channel fusing, and channel status LEDs make it an efficient and maintainable solution for remote I/O consolidation.

Select the DS200RTBAG1A when:

• Your field devices are located at a distance from the main Mark V rack

• You need to consolidate I/O wiring in a remote junction box or marshalling cabinet

• You need up to 64 field connections in a remote location

• You have a clean indoor environment (no conformal coating required)

For most applications, the DS200RTBAG1A is the standard remote terminal solution for Mark V distributed systems. For harsh environments, consider the coated DS200RTBAG1ADC variant or use external protective measures (sealed enclosures, field-applied conformal coating).

When sourcing the DS200RTBAG1A, ensure functional testing of all channels and LEDs is performed. With proper installation and maintenance, this board will provide years of reliable, remote I/O termination for Mark V turbine control systems.
