IC3600SSVB1B1B Servo Pressure Control Card

The IC3600SSVB1B1B is cataloged as a servo pressure control card within GE's Mark I / Mark II Speedtronic (IC3600) turbine control system, and is offered here as a clean, tested, used board. It belongs to the same IC3600 servo group as the SSVA control card and SSVG valve-drive card, but the fourth letter B marks it as a distinct function within that group.

The SSVB's Place in Speedtronic Servo and Pressure Regulation

Across the IC3600 servo series, each card handles one part of the chain that turns a control reference into precise hydraulic actuator motion. The SSVB is identified by GE-parts references as the servo pressure control member of that chain, associated with the pressure-regulation side of the hydraulic servo control rather than the valve-drive or feedback functions handled by the SSVG and SSVF. Detailed public documentation for the SSVB is sparse as is common for Mark I-II era boards so we describe its role at the level the sources support and avoid asserting pin-level or electrical specifics we cannot confirm. If you can share the schematic reference or elementary sheet for your panel, we can help confirm exactly where your SSVB sits.

Before You Replace: Isolating a Pressure or Servo Symptom

As with any servo-loop board, the symptom that looks like the card frequently originates elsewhere in the hydraulics or feedback. Work outward before swapping the SSVB:

• Check hydraulic supply and pressure. Confirm the servo/hydraulic supply is within its normal band; a pressure symptom often starts at the pump, filter or relief, not the card.
• Verify feedback and command. Confirm the feedback signal and the incoming reference are present and sensible.
• Inspect adjustments. A drifted trim or null can shift behavior without a failed component.
• Service the connector. Reseat the board and clean the edge fingers; oxidation is a common intermittent-fault source on aged cards.
• Confirm DC supplies. Rule out a marginal supply rail feeding the servo nest.

Understanding the SSVB1B1B Ordering Code

The number is function code IC3600SSVB followed by the variant and revision string 1B1B. The leading SSVB fixes the function; the trailing characters identify the specific variant and hardware revision. Because SSVA, SSVB, SSVE, SSVF, SSVG and SSVJ are genuinely different cards, confirm the full letter-and-dash string against your installed board before ordering. The GE Speedtronic Part Number Decoder walks through these fields.

Related IC3600 Servo-Series Boards

Alongside the SSVB you will typically find the SSVA servo control card, the SSVG servo valve drive card and the SSVF servo valve feedback card, together with the analog and power-supply cards in the same rack.

Getting an Accurate Quote for the SSVB

Please send the full part number (IC3600SSVB1B1B), the revision printed on the board, a photo of the label and component side, your turbine model and Speedtronic generation, the quantity, and how urgent the requirement is. If you have the panel's elementary or schematic reference, include it it helps us confirm the exact card.
