MELSEC-F Series Analog Input/Output

MELSEC-F Series Analog Input/Output

It is a high-accuracy analog input/output adapter with 12-bit binary resolution.
[Features]
・ Two channels of input (voltage: 0 to 10 V DC, or current: 4 to 20 mA DC) and 1 channel of output (voltage: 0 to 10 V DC, or current: 4 to 20 mA DC) are possible
・ Voltage or current input can be specified for each channel
・ Data can be transferred without a program (without dedicated instructions)
[Applications]
・ It is convenient for converting analog input signals to digital values and digital values to analog output signals
