Technical Specifications

Key Features and Benefits
High-Resolution Signal Conversion
The KJ4110X1-BA1 employs a 24-bit analog-to-digital converter (ADC) to capture minute variations in sensor signals, ensuring precise control in critical processes. This high resolution minimizes quantization errors, making it suitable for applications like pharmaceutical manufacturing and semiconductor fabrication where accuracy is paramount.

Flexible Input Configuration
Each channel supports multiple signal types, including voltage (±10 V) and current (0–20 mA), with software-configurable scaling and offset adjustments. This eliminates the need for external signal conditioners, reducing system complexity and cost. The module also features programmable digital filtering to suppress noise from industrial environments.

Robust Isolation and Reliability
Channels are galvanically isolated to prevent ground loops and electrical interference, enhancing measurement stability. The KJ4110X1-BA1 includes overvoltage and overcurrent protection, safeguarding against accidental sensor failures or power surges. Its rugged design meets IEC 61131-2 standards for industrial use.

Seamless System Integration
With support for Modbus RTU/TCP and PROFIBUS DP, the KJ4110X1-BA1 integrates effortlessly with PLCs, DCSs, and SCADA systems from major vendors. The module’s compact size (120 x 100 x 40 mm) allows dense mounting in control cabinets, while LED indicators provide real-time status feedback for easy commissioning.
