8 relay outputs for FX3U backplane
The FX2N-8EYR-ES is a PLC expansion module carrying 8 relay outputs, designed to mount on the FX3U series programmable controller backplane. Each relay output switches loads up to the module's 75 mA current draw from the 24 V DC supply rail — the relay contacts themselves handle higher load currents per the FX3U output specification, but the module's own consumption stays at 75 mA.
End-of-life sourcing reality
Available through independent surplus and broker channels; quantities are lot-specific and confirmed at RFQ.
Panel integration fit
The module snaps onto the FX3U DIN-rail backplane alongside the CPU and other I/O slices — the 8 relay outputs occupy one slot position and connect via the ribbon-cable bus at the rear of the rack. Wiring the relay commons and individual output terminals follows the standard FX3U terminal layout; the 24 V DC supply is drawn from the backplane bus, not a separate field power terminal.
