IC3600SLEH1G1C New-Surplus Logic Element Card

This is the IC3600SLEH1G1C offered as new-surplus, no-box stock: an unused SLEH logic element card at the "1C" revision, backed by a one-year warranty. It is aimed at operators who want an unused spare on the shelf for a Mark I or Mark II Speedtronic turbine rather than waiting for a unit-down emergency.

Inside the SLEH: OR Elements, AND Gates, and Relay Drivers

The SLEH's usefulness comes from a simple, repeated logic cell. Reference material describes each cell as an 'OR' logic element controlled by two 'AND' gates the output latches to '1' when either AND gate sees all-'1' inputs with three such cells on the one board. Each cell feeds a relay or driver output that connects to a common terminal when its output is true. Because the inputs accept high-level signals, expander gates can sit directly on the standard inputs, and an OR-E expander input is provided for pairing with an expander card like the LLXA. The board is listed on a 51-pin edge connector and can be tied to external annunciators.

A Field Checklist Before You Commit to a Purchase

Keeping an unused spare is smart; replacing a working card for the wrong reason is not. If the card in service looks suspect, confirm the fault first:

• Inputs before outputs. The output only asserts when the gated inputs are all present, so trace the inputs before assuming the gate has failed.
• Check the supply. Rule out a marginal DC rail from the Speedtronic power-supply cards.
• Clean the edge connector. Reseating and cleaning the 51-pin fingers clears a surprising number of "faults" on aged cards.
• Confirm the driven device. Test the downstream relay or annunciator and its wiring.
• Include the expander. If an LLXA and the OR-E input are in use, verify them too.

Matching the Full IC3600SLEH1G1C Ordering String

Order to the whole number: IC3600SLEH is the function, 1G the variant, and 1C the revision. The trailing character is what separates this dash from the 1B revision, so confirm it against the board you are replacing. The GE Speedtronic Part Number Decoder shows how each segment is read.

Where the SLEH Fits Among GE Speedtronic Generations

The IC3600 series is the Mark I / Mark II era the oldest Speedtronic hardware, built from discrete logic and analog cards rather than microprocessors. Later Speedtronic generations replaced these plug-in logic cards with software function blocks, so the SLEH is specific to the early panels. For matching hardware, our GE Mark I-II IC3600 Cards collection covers the same generation, and the full GE Speedtronic Turbine Control Boards range spans the wider Speedtronic line.
