Each channel is optically isolated from the PLC backplane via photocouplers, and the input voltage is DC 5 V — matching standard differential encoder outputs. The adapter draws 30 mA from both the DC 5 V and DC 24 V internal PLC supplies. ## Counting range and I/O mapping The hardware counter supports a signed 32-bit count range from -2,147,483,648 to +2,147,483,647, with count direction and comparison output handled by the sequence program. The adapter occupies four input points on the base unit: connecting the first adapter uses X000–X002 and X006; a second adapter uses X003–X005 and X007. A function expansion board is required on the base PLC when also connecting analog or communication adapters, but not when only the high-speed input/output adapter is used. ## Grounding and environmental limits Class D grounding (grounding resistance 100 Ω or less) is specified, with the instruction that grounding should be dedicated or common — not shared with high-noise equipment. The withstand voltage between the high-speed input terminals and the PLC earth terminal is AC 500 V for 1 minute; insulation resistance is 5 MΩ or more at DC 500 V. Operating ambient temperature is 0 to 55 °C, storage -25 to 75 °C, with 5 to 95% RH non-condensing. The adapter is not rated for use above 2000 m altitude or in atmospheres with corrosive gas or conductive dust. ## Lifecycle and sourcing The FX3U-4HSX-ADP is in a mature lifecycle stage — still available through distribution channels, not marked for discontinuation. No official successor or cross-reference to the LJ71E71-100 or FX5-CCLGN-MS exists; those are different-function modules (Ethernet and CC-Link respectively) and do not drop in as replacements.","metaTitle":"Mitsubishi Electric FX3U-4HSX-ADP High Speed Input Adapter","metaDescription":"Mitsubishi Electric FX3U-4HSX-ADP high-speed input adapter, 4 channels, 200 kHz 1-phase input, differential line receiver.
