Analog Input Module – 4 Current/Voltage Inputs

Product Overview

A compact 4‑channel analog input module designed to extend signal acquisition in modular PLC systems. Each channel supports both current and voltage signals, making it suitable for a wide range of industrial sensors and transducers. With selectable 14‑bit or 16‑bit resolution and conversion speeds under 0.5 ms, it ensures fast and precise measurements. Screw‑type terminal connectors provide secure wiring, while the external 24 VDC supply delivers stable operation.
