R-IB IL AI 2/SF-230-PAC

The Bosch Rexroth Indramat R-IB IL AI 2/SF-230-PAC is a precision analog input module in the R-IB Interface Modules series designed for industrial automation applications. Manufactured by Bosch Rexroth Indramat, this module features 2 analog single-ended inputs and a high resolution of 16 bits, providing fine granularity in signal measurement. It supports a versatile voltage input measuring range of 0 to 10 V and ±10 V, allowing seamless integration with a wide array of sensors and transducers. The primary function of this module is to convert analog voltage and current signals into digital process data for Inline station networks, ensuring real-time monitoring and control in automated production environments.

In technical operation, the R-IB IL AI 2/SF-230-PAC delivers a Conversion Time Of A/D Converter of typically 120 µs, enabling rapid acquisitions of analog signals. It employs an Input Filter Frequency of 230 Hz (–3 dB) to suppress noise and stabilize measurements. The module offers three selectable Current Input Measuring Ranges (0 to 20 mA, ±20 mA, and 4 to 20 mA) alongside its voltage ranges. With an Input Resistance exceeding 220 kΩ for voltage channels and precision shunt resistors for current inputs, the module ensures stable signal conditioning. It operates from a Peripheral Supply Voltage (uana) of 24 V DC, drawing typically 12 mA, and consumes 45 mA from the local bus (ul), with a logic reference voltage of 7.5 V.

Built to withstand industrial conditions, the R-IB IL AI 2/SF-230-PAC is rated IP20 for protection against solid objects and fits a compact housing of 12.2 x 135 x 71.5 mm. Weighing only 47 g, it minimizes panel load while maintaining structural integrity. The module communicates at a Transmission Speed of up to 500 kbaud in process data mode, handling two data words per cycle and ensuring under 1.5 ms response times for critical control loops. The dual-input architecture and automatic voltage channel default to 0 V on power-up enhance operational safety. Overall, this analog input module offers reliable signal acquisition, efficient data throughput, and robust durability—key advantages in modern industrial automation systems.
