2.7 Built-in Analog Specifications
The analog input/output specifications of the built-in analog function are explained below.
For details on the analog built-in function, refer to MELSEC iQ-F FX5 User's Manual (Analog Control).
Analog input
*1 "Digit" refers to digital values.
Analog output
*1 There is a dead band near 0 V output, which is an area where some analog output values do not reflect digital input values.
*2 External load resistance is set to 2 k when shipped from the factory. Thus, output voltage will increase somewhat if the resistance is
set higher than 2 k. When the resistance is 1 M, output voltage increases maximum 2%.
*3 "Digit" refers to digital values.
Item Specifications
Analog input points 2 points (2 channels)
Analog input Voltage 0 to 10 V DC (input resistance 115.7 k)
Digital output Unsigned 12-bit binary
I/O characteristics, Maximum resolution Digital output value 0 to 4000
Maximum resolution 2.5 mV
Accuracy
(Accuracy in respect to maximum digital
output value)
Ambient temperature
25 5 (77 41)
Within 0.5% (20 digit
