High‑Precision Analog Input
for CONPROSYS nano

The CPSN‑AI‑1604LI is an expansion I/O module for the CONPROSYS nano series, adding 4 channels of 16‑bit differential analog input. The module supports both voltage and current input — switchable per module via on‑board switch — and input ranges are software‑selectable. Bus isolation (500VDC) ensures reliable measurement even with potential differences between the module and signal source.

Analog Input
  • 4 differential channels
  • 16‑bit resolution
  • Voltage or current input
  • Software‑selectable ranges
  • Bus isolated (500VDC)
Key Features
  • ‑20 to +60°C operation
  • Tool‑less installation
  • No electrolytic capacitors
  • Differential input
  • 10‑pin terminal connector

Differential input – accurate measurement even when potential differences with the signal source occur. Voltage and current input are switchable via the on‑board switch, with ranges set by software.

Built for Harsh
Industrial Environments

Designed for demanding factory and process automation applications. The CPSN‑AI‑1604LI operates across a wide temperature range (-20 to +60°C) and is built without electrolytic capacitors for extended product life. The module installs and removes without tools, simplifying system maintenance.

  • Wide temperature range – Operates from -20 to +60°C for installation in diverse environments.
  • Long life design – No electrolytic capacitors, which have limited operational life.
  • Tool‑less installation – Easily install and remove from the CPU unit without any tools.
  • Bus isolation – 500VDC isolation protects the system from ground loops and transients.
  • Compact form factor – 15.6(W) × 52.6(D) × 84(H) mm, weight only 50g.
