CT-3238: 8-channel analog input module for voltage and current signals

C Series remote I/O system
The C Series is a modular remote I/O system, composed of a network adapter and pluggable I/O extension modules, ideal for distributed industrial applications.

The analog input module CT-3238 is an 8-channel analog input I/O unit designed for high-precision acquisition of both voltage and current signals. It supports multiple input ranges including 0–5 V, 0–10 V, ±5 V, ±10 V, 0–20 mA, and 4–20 mA, with a high-resolution 16‑bit A/D conversion for accurate signal measurement in Odot analog module applications.

Key features

Input channels: 8 independent analog input channels, ideal as an analog input 8 channel module.
Supported signal types:

• 0–5 VDC
