DS200RTBAG2A GE

Key Technical Parameters

Advantages & Core Features

• Increased terminal capacity – The DS200RTBAG2A provides 80 terminals (5x 16-terminal blocks), a 25% increase over the 64-terminal “G1A” models, accommodating more remote field connections on a single board.

• Higher output current capacity – Each output channel supports up to 2A (double the 1A capacity of G1A models), enabling direct control of higher-power field devices without external interposing relays.

• Multi-signal type support – Supports analog inputs, digital inputs, digital outputs, thermocouple, and RTD connections.

• Individual channel fusing – Each output channel is protected by a user-replaceable fuse (20 total), preventing field wiring faults from damaging the board or backplane.

• Channel status LEDs – 20 LEDs provide immediate visual indication of output channel status, simplifying troubleshooting in remote locations.

• Screw-clamp terminals – Rise-clamp screw terminals with dual-wire entry provide secure, reliable connections.

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

• Compact 1-slot form factor – Occupies a single slot.

Key Differences vs. DS200RTBAG1A (First-Generation “G1A” Model)

Application Cases

• Distributed steam turbine with high-power outputs – A chemical plant uses the DS200RTBAG2A in a remote marshalling cabinet to consolidate 40 analog inputs and 20 high-current outputs (2A each) for direct control of solenoid valves, eliminating external interposing relays.

• Offshore platform with dense remote I/O – A North Sea platform uses the DS200RTBAG2A in remote junction boxes near compressors, maximizing I/O density (80 terminals) in compact enclosures.

• Gas turbine with remote auxiliary systems – A combined-cycle plant uses the DS200RTBAG2A to terminate I/O from auxiliary systems (lube oil, cooling water) with higher current requirements.

• Large hydroelectric plant with distributed architecture – A dam facility uses the DS200RTBAG2A in remote cabinets near the turbine hall, consolidating I/O with the increased 2A capacity.

Comparison with Related Variants

Selection Suggestions

1. Assess distribution requirements – Select the DS200RTBAG2A if your field devices are located at a distance from the main Mark V rack and you need higher capacity remote I/O consolidation.

2. Count your I/O terminations – The DS200RTBAG2A supports up to 80 terminals. Use this board if you have more than 64 remote field connections.

3. Check output current requirements – Select the DS200RTBAG2A if your output devices require more than 1A per channel (up to 2A).

4. Confirm signal types – Ensure the board supports the required field signal types.

5. Verify communication interface – Ensure the board’s interface is compatible with your Mark V rack configuration.

6. Verify fuse ratings – Ensure that the 2A fuse ratings match your output channel current requirements.

7. Assess environmental conditions – The DS200RTBAG2A has no conformal coating. For harsh environments, consider using external protective measures (sealed enclosures, field-applied conformal coating). Note that there is no coated version of the “G2A” model – if coating is required, you must use the DS200RTBAG1ABB or DS200RTBAG1AEB (64 terminals, 1A per channel) or the DS200RTBAG1AFB (64 terminals, fieldbus, 1A per channel).

8. Procurement – The DS200RTBAG2A is exceedingly rare. Purchase from reputable suppliers offering functional testing (channel verification, fuse testing, LED testing). Lead times: 14-18 weeks.

9. Stock spares – Maintain at least one spare on-site.

Important Precautions

• Power down completely – De-energize the entire system before insertion or removal. 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 (2A). The higher current rating requires appropriately sized fuses.

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

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

• Check total current draw – Ensure the total current draw on each rail does not exceed the board’s capacity.

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

• Storage – Store at 10-30°C, 20-50% RH. Rotate every 24 months.

Final Expert Recommendation

The DS200RTBAG2A is a high-capacity remote terminal board designed for Mark V installations requiring enhanced terminal capacity (80 terminals) and higher output current capacity (2A per channel). It is the ideal solution for consolidating a large number of remote field I/O connections while supporting direct control of higher-power field devices.

Select the DS200RTBAG2A when:

• You have more than 64 remote field connections to terminate (up to 80)

• Your output devices require more than 1A per channel (up to 2A)

• You need remote I/O consolidation with higher capacity

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

• You cannot use the coated “G1A” variants due to insufficient capacity or current limitations

However, note that the DS200RTBAG2A has no conformal coating. For harsh environments, you must choose between:

• The DS200RTBAG1ABB, DS200RTBAG1AEB, or DS200RTBAG1AFB (coated, 64 terminals, 1A per channel) – if that capacity and current is sufficient

• The DS200RTBAG2A with external protective measures (sealed enclosures, field-applied conformal coating) – if the higher density and current are essential

For most applications, the DS200RTBAG1A (64 terminals, 1A per channel) is sufficient for standard remote I/O termination. The DS200RTBAG2A should be reserved for higher-density or higher-current remote applications where the “G1A” models are inadequate.

When sourcing the DS200RTBAG2A, ensure functional testing of all channels and LEDs is performed. With proper installation and maintenance, this board will provide years of reliable, high-capacity remote I/O termination for demanding Mark V turbine control systems.
