The Mitsubishi A1S64AD module is a MELSEC-A series A/D converter module that was designed to be used in analog-to-digital signal conversion applications. It accommodates both voltage and current analog input signals. The A1S64AD module’s analog input voltage signal range is -10 to 0 to +10VDC with an input resistance rating of 1MΩ, and the analog input current signal range is -20 to 0 to +20mA with an input resistance rating of 250Ω. The A1S64AD module supports 16-bit coded binary digital input signals. It also supports a maximum conversion speed of 20ms per channel. The A1S64AD module can handle maximum absolute input ratings of ±15V for voltage and ±30mA for current. It provides 4 analog input channels. The A1S64AD module uses photocoupler isolation between the input terminal and the PLC power supply. The module’s dielectric withstand voltage rating between the input terminal and the PLC power supply is 500V AC for 1 minute, and insulation resistance measures 5MΩ or more (tested using a 500V DC insulation resistance tester). The A1S64AD module occupies 32 special I/O points. The module’s connection terminal features a 20-point terminal block, and it does not require an external power supply. The applicable wire size range for this module is from 0.75mm² to 1.5mm², with compatible crimp terminals including 1.25-3, 1.25-YS3, V1.25-3, and V1.25-YS3A. The A1S64AD A/D converter module has an internal current consumption rating of 0.4 A at 5V DC, and it weighs 0.25 kg. The A1S64AD module can be used with a Mitsubishi MELSEC-A series CPU module.
