S20-DI-32/1

The S20-DI-32/1 from Bosch Rexroth Indramat represents a high-performance module within the S20 IndraControl Modules series, designed for advanced industrial automation environments. This digital input module features a compact profile of 12.5 mm x 120 mm x 54 mm and integrates seamlessly with DIN rail infrastructures. Engineered to handle 32 digital inputs at 24 V DC, it delivers reliable signal acquisition for a wide range of automated systems. The robust plastic housing provides IP20 protection while maintaining a lightweight form factor that simplifies installation in densely populated control cabinets. With a typical current consumption of 40 mA and lightning-fast data handling, this module is ideal for modern servo and motion control applications.

Technical capabilities of the S20-DI-32/1 include an input filter time of 0.05 ms (typical), ensuring rapid response to state changes and precise synchronization in high-speed processes. The module communicates via the S20 system bus at 100 Mbps transmission speed, enabling low-latency data exchange with the central controller. Each input channel is isolated to 500 V (test voltage) between channels and bus, safeguarding system integrity against electrical interference and ground loops. Status LEDs per channel provide instant visual feedback for diagnostics and channel status, while the spring-cage connection method guarantees secure wiring without the need for tools. The digital input type is engineered to interface with standard 24 V DC sensors and switches, facilitating straightforward integration into existing control schemes.

Operationally, the module withstands industrial stresses with an operating temperature range from –25 °C to +60 °C and can survive transport extremes of –40 °C to +85 °C prior to installation. Its design meets over-voltage category II requirements, and it has been tested to endure vibration levels up to 5 g and shock levels up to 30 g, ensuring dependable performance in vibration-intensive environments. The module’s DIN rail mounting type simplifies field upgrades and maintenance, reducing downtime and labor costs. With a minimal footprint and a wire-to-bus cycle time optimized for servo systems, the S20-DI-32/1 enhances machine responsiveness and throughput.

Integration of the S20-DI-32/1 into automation architectures is straightforward: it slots directly onto the S20 bus base, automatically recognizing its identity and allowing plug-and-play commissioning. Compatible with Bosch Rexroth IndraControl controllers, it supports expansion up to 63 modules per station, offering scalable I/O configurations. Its combination of compact dimensions, high channel count, and comprehensive protection features makes it ideal for packaging machines, conveyor systems, robotics, and process control applications where space is limited but performance cannot be compromised.
