Specifications Parameter Category Details Manufacturer & Series Schneider Electric, Advantys STB Complete Model Number STBACI1230K Module Type Analog Input Module (Current) Fieldbus System Part of the Advantys STB system; requires an STB island bus interface module (e.g., for Ethernet, PROFIBUS) to connect to a PLC or controller. Number of Channels 2 Input Signal Type Current Supported Current Ranges (Software Configurable) 0 to 20 mA and 4 to 20 mA Resolution 12 bits (including sign) Input Impedance 250 Ω Accuracy (at 25°C / 77°F) Typically ±0.3% of full scale Common Mode Rejection Ratio (CMRR) > 90 dB at 50/60 Hz Isolation Channel-to-channel isolation: Yes Channel-to-bus isolation: 500V AC Conversion Time per Channel Typically 3 ms Data Format • For 4-20 mA range: 0 to 27648 (4mA = 0, 20mA = 27648) • For 0-20 mA range: 0 to 27648 (0mA = 0, 20mA = 27648) Wiring Removable screw terminal block (front connector). Status Indicators • Module Status LED (Bicolor): RUN/ERR (Green/Red) for power and communication. • Channel Status LEDs (Green, one per channel): Indicates valid input within range. Power Supply Powered from the 24V DC Advantys STB island bus. Power Consumption from 24V DC Bus Typically 75 mA Operating Temperature 0°C to +60°C Storage Temperature -25°C to +85°C Relative Humidity 5% to 95% (non-condensing) Protection Rating IP20 (for installation inside an enclosure) Mounting Mounts on a standard Advantys STB mounting base (e.g., STBNDMxxxx), which is snapped onto a DIN rail (35mm). Configuration Software Advantys Configuration Software (ACS) or integrated within some PLC programming environments (like EcoStruxure Control Expert). Typical Applications Connecting 4-20 mA transmitters for temperature, pressure, level, flow rate, or analog signal monitoring in process control, HVAC, and industrial automation systems.
