Product Overview
When you need reliable analog signal acquisition in a distributed I/O system, the Schneider Electric STBACI1230K standard analog input kit delivers precision and flexibility. This kit combines the STBACI1230 module, STBXBA1000 base, STBXTS1100 screw connector, and STBXTS2100 spring clamp connector for quick installation. Designed for the Modicon STB distributed I/O solution, it handles 0-20 mA current signals with 12-bit resolution, making it ideal for process monitoring and control.
Technical Specifications Breakdown
The STBACI1230K offers two analog current inputs with a 12-bit resolution, ensuring accurate measurement of 0-20 mA signals. A single low-pass input filter at 25 Hz reduces noise, while the response time of 5 ms keeps data fresh. The update time is 10 ms, and integral linearity is ±0.1% FS, with absolute accuracy error of ±0.5% of full scale at 25 °C. Temperature drift is only ±0.01%/°C, maintaining stability across the operating range of -25 to 70 °C. Input impedance is ≤300 Ohm, and each channel provides 100 mA supply current for sensors, with short-circuit protection.
Industry Applications
In manufacturing, the STBACI1230K monitors analog sensors like pressure transmitters or flow meters. For example, in a water treatment plant, it reads 0-20 mA signals from level sensors, feeding data to a PLC for pump control. The 1500 V insulation between channels and the logic bus ensures reliable operation in electrically noisy environments. Its compact dimensions (70 mm depth, 13.9 mm height, 128.3 mm width) allow dense mounting on DIN rails.
Installation & Setup Guidance
Mount the STBACI1230K on a 35 mm symmetrical DIN rail using the STBXBA1000 base. Connect sensor wiring to the provided STBXTS1100 screw or STBXTS2100 spring clamp terminals. Use a power distribution module like STBPDT3100/3105 for 24 V DC supply. The module consumes 30 mA from the 5 V DC logic bus. Addressing requires 4 input words. The green RDY LED indicates module status, and the red ERR LED signals errors.
Maintenance & Reliability
The STBACI1230K supports cold swapping and hot swapping fallback for standard NIMs, minimizing downtime. Fallback state is configurable for standard NIMs. With IP20 protection and pollution degree 2 compliance, it suits clean industrial environments. The module withstands vibration up to 3 gn at 58-150 Hz and shock up to 30 gn. Regular inspection of connections and LED status ensures long-term reliability.
Compatibility & Integration
This kit integrates with the Modicon STB distributed I/O solution. It uses EN 61131-2 and IEC 61131-2 data formats. The module is compatible with the STBXBA1000 mounting base and power distribution modules STBPDT3100/3105. It carries certifications including CE, ATEX Cat 3G, CSA, C-Tick, FM Class 1 Division 2, and UL.
