Product Type: Vibration Detector Board (SCB)
IC3600SVDC1D is a Vibration Detector Board manufactured by GE Fanuc. It is a part of Mark I and II used in gas turbine control systems. Its primary function is to detect excessive vibration levels from connected sensors and initiate protective or warning actions when necessary. This is critical in turbine applications where high vibration can indicate mechanical imbalance, misalignment, or failure of rotating equipment.
Once latched, the alarm output can be reset by either:
This latching behavior ensures that transient or momentary vibration spikes are not ignored and require operator acknowledgment.
To enhance reliability, the SVDC card includes a sensor fault detection feature, which identifies:
When a sensor fault is detected:
The fault latch must be reset either via the local pushbutton or a remote signal similar to the vibration latch circuit.
The card uses input impedance monitoring to validate sensor health. Depending on the installed jumper configuration, the expected impedance range for a no-fault condition is as follows:
These impedance values ensure that sensors are functioning correctly and help distinguish between wiring issues and actual sensor faults.
The vibration trip point (via R1) is adjustable over the range of 0.25 to 1.6 inches/second, providing flexibility for various equipment and sensitivity requirements.

What is GE Fanuc IC3600SVDC1D?
It is a Vibration Detector Board used in gas turbine control systems.
How does the card detect sensor faults?
The card uses input impedance monitoring to check whether the connected sensor is operating within an acceptable range. If the impedance falls outside the specified limits, it identifies the sensor as faulty (shorted or open).
What happens when a sensor fault is detected?
When a fault is detected, the card Latches Output A to 1, illuminates the trouble light, and requires a manual or remote reset to clear the fault indication.
