S20-AI-8

The S20-AI-8 analog input module from Bosch Rexroth Indramat is part of the S20 IndraControl Modules series, designed for precise acquisition of industrial signals. This module features eight isolated input channels capable of handling both 0-10V DC and 0-20mA/4-20mA ranges, ensuring compatibility with a wide array of transmitters and sensors. With a high resolution of 12-Bit, the S20-AI-8 delivers accurate digital encoding for applications in process control, monitoring, and data acquisition within automation systems.

Building on its core capabilities, the S20-AI-8 offers a fast conversion time of 1 ms per channel, allowing real-time processing in dynamic environments. Each channel provides channel-to-channel and channel-to-bus isolation, significantly reducing electrical noise, ground loops, and cross-channel interference to enhance measurement reliability. The module supports an input impedance of 100 kΩ for voltage inputs and 250 Ω for current inputs, and operates over a temperature range of –20 °C to +60 °C on a standard 24 V DC supply. Its robust design ensures stable performance in harsh industrial settings, maintaining signal integrity and system uptime.

For installation, the S20-AI-8 mounts easily on DIN rails and occupies a compact footprint of 52.5 mm × 100 mm × 70 mm (W×H×D), weighing approximately 180 g for streamlined control cabinet layouts. It sustains storage conditions from –40 °C to +85 °C, supporting long-term durability during transport or downtime. Featuring rugged construction and comprehensive isolation, this module meets the demands of modern automation architectures. By integrating the S20-AI-8, system designers gain enhanced signal fidelity, improved noise immunity, and efficient space management—delivering reliable performance across industrial automation, building control, and energy-monitoring applications.
