The Mitsubishi FX2N-1HC is a 1-channel high-speed counter block designed for the FX2N, FX3U, FX2NC, and FX3UC PLC families. It accepts encoder inputs in open collector or differential line driver format (the latter wired to the 5 V terminal). Maximum count rate hits 50 kHz in 1-phase-1-input mode, and with 2-phase inputs you get 50 kHz at 1x multiplication, 25 kHz at 2x, and 12.5 kHz at 4x. Power is drawn from the PLC backplane at DC 5 V 90 mA — no external supply needed, but it does occupy 8 I/O points in the PLC's address map.

Frequently asked questions
What is the mass of the FX2N-1HC?
0.3 kg per unit. Shipping weight is 2 kg due to packaging.
What are the key electrical specifications?
DC 5 V 90 mA from the PLC backplane. Max response frequency 50 kHz (1-phase-1-input). Inputs accept open collector or differential line driver at selectable voltage (5, 12, or 24 V). Two open-collector comparison outputs at 5–24 V, 0.5 A.
Does the FX2N-1HC work with FX3U or FX3UC PLCs?
Yes, it's compatible with FX2N, FX3U, FX2NC, and FX3UC. For FX2NC or FX3UC, an FX2NC-CNV-IF adapter is required; for FX3UC, the FX3UC-1PS-5V may also be needed.
