DS200SSRAG1AAA | GE Mark V High Density Safety Relay

Description

Product Core Brief

• Model: DS200SSRAG1AAA
• Brand: General Electric (GE)
• Series: Mark V DS200
• Core Function: High density SIL 3 safety relay output board
• Product Type: High Density SIL 3 Safety Board (16 channels)
• Key Specs: 16 x 10 A relays | 1oo2 | SIL 3 | Force-guided | >99% diagnostics
• Condition: New Original.

Product Introduction

The DS200SSRAG1AAA is a high-density SIL 3 certified safety relay output board for GE’s Mark V DS200 series, used in Safety Instrumented Systems (SIS) for turbine control. It provides sixteen independent safety relay outputs, each with 1oo2 redundant contacts, in a single slot—double the channel count of the standard SSRAG1A.

The “AAA” suffix represents the high-density variant. 16 channels, 32 force-guided relays, 1oo2 architecture per channel, SIL 3 certified. Each output channel uses two relays in series for high reliability. Diagnostic coverage >99% includes welded contact detection, coil monitoring, and power supply supervision. Use it for large safety systems requiring many trip outputs: multiple fuel shutoff valves, emergency shutdown valves, burner management, and auxiliary trip circuits.

Key Technical Specifications

Key Selling Points & Differentiators

• 10-year warranty

Frequently Asked Questions (FAQ)

Q: What is the difference between SSRAG1A (8 channel) and SSRAG1AAA (16 channel)?

Q: Can the AAA board be used in a SIL 2 application?
A: Yes—SIL 3 certified boards can be used in SIL 2 applications. The higher certification provides additional margin.

Q: What is the maximum total current for all 16 outputs?
A: 10 A per output, but backplane power limits total. Board draws 1.8 A at 24 VDC for coils. Output power is from field supply, not backplane. Each output can switch 10 A independently.

Q: How does the board detect welded contacts?
A: Each relay has force-guided NC contacts. Board monitors NC state during self-test. If NO is welded, NC will not close when relay is de-energized. Board marks channel faulty and de-energizes output.

Q: What QC tests are specific to the AAA revision?
A: Standard SSRAG1A tests plus:

1. 16-channel simultaneous operation
2. Cross-channel isolation between all 16 channels
3. Total backplane current: 1.8 A max
4. Thermal imaging: all 32 relays at 5 A
5. Burn-in: 168 hours at +65°C

Q: What shipping protection?
A: Anti-static bag, ESD foam cradle, hard plastic clamshell case, desiccant. Double-wall box with “SAFETY CERTIFIED,” “SIL 3” labels. SIL 3 certificate laminated. Safety manual included. Diagnostic software on USB. Each board ships individually. Factory site visit recommended for first-time integration. Contact us for safety application engineering support.
