Description
The FX2N-2AD is a 2-channel analog input module designed for Mitsubishi FX2N series PLCs. It converts analog signals (voltage or current) into digital values for processing in industrial automation systems.
Key Features
-
Channels: 2 isolated analog inputs.
-
Signal Types: Supports 0–10V DC voltage or 4–20mA current per channel (configured via wiring, not software).
-
Resolution: 12-bit (0–4095 digital range).
-
Conversion Time: 2.5ms per channel.
-
Isolation: Photocoupler isolation between analog and PLC circuits.
-
Compatibility: Integrates with FX2N PLCs via the extension bus.
