MELSEC-Q Series

Analog I/O

A wide range of application specific intelligent modules

A range of analog modules ideal for process control applications.

Isolated analog modules suitable for process control

System configuration example

Channel isolated high resolution analog-digital converter module Q64AD-GH

Channel isolated high resolution analog-digital converter module (with signal conditioning function) Q62AD-DGH

Channel isolated high resolution digital-analog converter module Q62DA-FG

Channel isolated analog-digital converter module Q68AD-G

Channel isolated analog-digital converter module (with signal conditioning function) Q66AD-DG

Channel isolated digital-analog converter module Q66DA-G

The channel isolated analog modules are specifically designed for process control applications by offering high accuracy conversion combined with high isolation voltage. Flow meters, pressure gauges, etc. can be directly connected to the analog input, and control valves to the analog output. Hardware and installation costs can be substantially reduced because external isolation amplifiers are not required.
When used with a general purpose controller, a low cost process control solution can be created.

High dielectric withstand voltage

High dielectric withstand voltage

High conversion speed analog modules

System configuration example

High speed analog-digital converter module Q64ADH

Analog-digital converter module Q68ADV Q68ADI

Analog-digital converter module Q64DAH

Digital-analog converter module Q62DAN Q64DAN Q68DAVN Q68DAIN

Analog-digital/Digital-analog converter module Q64AD2DA

Many high-speed A/D and D/A conversion (analog) modules are available.
These modules are feature packed to allow maximum flexibility when connecting to devices. Both speed and accuracy are great enough to control sensitive motion applications using servos or inverters.
