Product Description

CT-4234 4 channels analog output /0&4-20mA/16-bit single-terminal

Module features

In process control applications, analog output modules often suffer from signal noise, fixed ranges, or insufficient isolation—leading to inaccurate actuator response and system instability.

The CT-4234 4-Channel Analog Output Module from Sichuan Odot Automation delivers a robust solution for high-fidelity continuous control. Featuring four 16-bit precision current outputs, it supports user-selectable ranges of 0–20mA or 4–20mA, enabling accurate driving of control valves, pneumatic actuators, VFDs, and transmitters—common in chemical processing, water treatment, HVAC, and energy management systems.

Its single-ended, common-ground output architecture simplifies field wiring, while magnetic isolation between the internal bus and field outputs provides exceptional immunity against ground loops and electrical noise, ensuring long-term reliability without external isolators. This reduces system complexity and total cost of ownership.

As a core output component of the ODOT open automation platform, the CT-4234 combines high accuracy, industrial-grade robustness, and engineering-friendly integration—empowering smarter, more dependable analog control loops for global industrial applications.
