Control, drive and protection hardware for plants that are still running equipment the original manufacturer no longer supports. Most of what sits in this category is obsolete, discontinued or end-of-life — Reliance Electric drives, GE Fanuc PLC racks, GE Multilin protection relays, Woodward governors, Allen-Bradley I/O, Foxboro DCS cards. These are the parts that cannot be bought new from the OEM and that a plant cannot run without.
What this category covers
AC and DC variable-frequency drives and their control, power and interface boards; PLC processors, racks, power supplies and discrete/analog I/O modules; protection and metering relays; turbine and generator governors, synchronisers and load-sharing controls; HMI and operator interface panels; machine-vision cameras, sensors and controllers; servo drives and motion controllers; process control cards and DCS modules.
Why part numbers matter more here than anywhere else
Industrial control boards carry revision levels, and a revision mismatch is not cosmetic — it changes firmware compatibility, backplane addressing and sometimes the physical connector. A DS200 board at one revision and the same board number at another are not always drop-in equivalents. We quote against the exact part number and revision printed on the board you are replacing, and we will tell you when a substitute is genuinely equivalent and when it is not.
