FX2N-4AD SPECIAL FUNCTION BLOCK USER’S GUIDE JY992D65201A This manual contains text, diagrams and explanations which will guide the reader in the correct installation and operation of the FX2N-4AD and should be read and understood before attempting to install or use the unit. Further information can be found in the FX SERIES PROGRAMMING MANUAL, FX2N SERIES HARDWARE MANUAL . 1 INTRODUCTION 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: 20µA) may be selected. Data transfer between the FX2N-4AD and the FX2N 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 points of I/O on the FX2N expansion bus. The 8 points can be allocated from either inputs or outputs. The FX2N-4AD draws 30mA from the 5V rail of the FX2N main unit or powered extension unit. 1.1 EXTERNAL DIMENSIONS Weight : Approx. 0.3 kg (0.66 lbs) 87(3.43) Mounting holes 4.5mm(0.18)dia. 4 55(2.17) Dimensions : mm (inches) 55(2.17) 24+ 24+ 24V+ 24V+ CH1 CH1 VI- VI- 90(3.54) 80(3.15) DIN rail Mounting slot 35mm(1.38) I+ POWER FG VIFG VIFG VI- CH2 CH3 CH4 V+ I+ V+ FX2N-4AD I+...
