STBACI1230K | Schneider Analog Input Kit Supplier

Introduction to the STBACI1230K

When your distributed I/O system demands reliable analog input processing, the STBACI1230K from Schneider Electric provides a compact solution. This standard analog input kit is part of the Modicon STB distributed I/O family, engineered for industrial environments where accuracy and durability matter. With two current input channels supporting 0-20 mA signals, it handles common process measurements with ease.

Core Specifications of the STBACI1230K

The STBACI1230K offers a 12-bit resolution for each analog input, ensuring fine granularity in signal conversion. Key parameters include:

• Input type: Current 0-20 mA
• Number of inputs: 2
• Resolution: 12 bits
• Absolute maximum input: 25 mA / 50 V DC
• Response time: 5 ms
• Update time: 10 ms
• Integral linearity: +/- 0.1 %FS
• Input impedance: <= 300 Ohm
• Supply current for sensors: 100 mA per input channel
• Absolute accuracy error: +/- 0.5 % of full scale at 25 °C

The kit includes the STBACI1230 module, STBXBA1000 base, and both screw-type and spring clamp connectors for flexible wiring.

Applications for the STBACI1230K

Engineers commonly deploy the STBACI1230K in process control and monitoring systems. It suits applications requiring precise current loop measurement, such as pressure, flow, or level sensing. Because it supports cold swapping and hot swapping with standard NIMs, maintenance teams can replace modules without system downtime, reducing production interruptions.

Installation and Setup Guide

Mount the STBACI1230K on a 35 mm DIN rail using the included STBXBA1000 base. Connect sensor wiring to the 6-terminal connectors (STBXTS1100 screw type or STBXTS2100 spring clamp). The module requires a 24 V DC supply from a power distribution module like STBPDT3100/3105. Addressing uses 4 input words, and the module draws 30 mA from the 5 V DC logic bus.

Maintenance and Reliability

Routine inspection of connections and environmental conditions helps maintain reliable operation. The STBACI1230K operates from -25 to 70 °C and withstands 95% relative humidity without condensation. Its IP20 protection suits clean industrial cabinets. The single low-pass input filter at 25 Hz reduces noise, improving signal stability over time.

Compatibility and Integration

The STBACI1230K integrates with Modicon STB distributed I/O systems. It works with standard NIMs for user-configurable fallback states and basic NIMs for state 0 fallback. The module supports CE marking and carries certifications including ATEX Cat 3G, CSA, C-Tick, FM Class 1 Division 2, and UL, making it suitable for hazardous locations.

Troubleshooting Common Issues

If the module does not respond, check the green RDY LED and red ERR LED on the front. Verify the 24 V DC supply from the power distribution module and ensure the logic bus current is within limits. For accuracy problems, confirm the input current does not exceed 25 mA and that wiring impedance is below 300 Ohm.
