IC3600SIXK1C1C Power Sensor Card overview

The IC3600SIXK1C1C is a power sensor card from the IC3600SIX group of GE's Speedtronic Mark I / Mark II turbine control, the oldest Speedtronic generation. Where the SIXJ in the same group selects a power source, the SIXK monitors one: it senses the panel's power supply and gives the control system status on whether the supplies are present and healthy. That distinction matters when you order, because the two cards share the SIX prefix yet do completely different jobs.

As a monitoring card, the SIXK is only as meaningful as the supplies it watches. It reports what it sees — which is exactly why it is so often blamed for faults that actually live in the power supply it is reporting on.

A sensed-power alarm may be telling the truth

The single most important thing to understand about a power sensor card is that a power alarm from it may be correct. Before you replace the SIXK to clear a warning, make sure you are not about to silence a valid one:

• Check the supplies it senses first. If the card is flagging a power problem, measure the actual EPS-group rails and incoming supplies. A genuine sag, ripple or missing rail should be corrected at the source, not masked by swapping the sensor.
• Separate a real fault from a sensing fault. Only if the monitored supplies are confirmed good does a persistent alarm point to the sensor's own input or reference circuitry.
• Reseat and clean the edge connector. A poor connection can feed the sensor a false reading; clean the edge fingers and reseat before condemning the card.
• Correlate with other symptoms. If other cards are misbehaving too, the common cause is far more likely to be the supply itself than the card that noticed it.

Replacing a power sensor to make an alarm go away, while leaving a real supply fault in service, is one of the more costly mistakes on a legacy panel. Confirm the supply before you decide the sensor is wrong.

Interpreting the IC3600SIXK1C1C code

IC3600 is the Mark I / Mark II card series, SIX the group and K this specific card — the power sensor — distinct from the J selector, the L extender and the M interface in the same group. The trailing 1C1C is the revision or dash detail to match alongside the base. Because the SIX group mixes several functions, always confirm the letter after SIX and the full suffix. See our GE Speedtronic Part Number Decoder for how the pieces fit together.

SIXK among the IC3600SIX cards

The group's four cards are easy to confuse: the SIXJ power supply selector, this SIXK power sensor, the SIXL relay module extender and the SIXM interface card. Catalog listings for these boards are sometimes swapped or mislabeled, so identify the card you need by its full part number rather than by the words beside it. You can review the group in our GE Mark I-II IC3600 Cards collection and the wider range in GE Speedtronic Turbine Control Boards. These cards are specific to Mark I-II and do not interchange with later Speedtronic generations, which also introduced the triple-redundant R/S/T voting architecture that this era predates.
