The FX2N-4AD analog special function block has four input channels. The input channels receive analog signals and convert them into a digital value. This is called an A/D conversion. The FX2N-4AD has maximum resolution of 12 bits.
• The selection of voltage or current based input/output is by user wiring. Analog ranges of -10 to 10V DC (resolution: 5mV), and/or 4 to 20mA, -20 to 20mA (resolution: 20 μA) may be selected.
• The FX2N-4AD can be connected to the FX0N/FX1N/FX2N/FX2NC/FX3U/FX3UC series Programmable Controllers (PLC).
• Data transfer between the FX2N-4AD and the main unit is by buffer memory exchange. There are 32 buffer memories (each of 16 bits) in the FX2N-4AD.
• The FX2N-4AD occupies 8 I/O points on the FX2N expansion bus. The 8 I/O points can be allocated from either inputs or outputs. The FX2N-4AD draws 30mA from the 5V rail of the main unit or powered extension unit.
