S20-SSDI-8/4
The Bosch Rexroth Indramat S20-SSDI-8/4 is a high-performance interface module in the S20 IndraControl Modules series, designed by Bosch Rexroth Indramat for safety-related digital input applications. This Type DIN Rail Terminal Block boasts a compact Module Width of 12.5 mm and accommodates Number Of Digital Inputs 8 channels for comprehensive signal acquisition. It operates on a standard Input Voltage of 24 V DC and provides built-in Short-circuit Protection for each channel, ensuring system integrity under fault conditions. The module’s Connection Type screw terminals deliver secure, vibration-resistant wiring, while its Number Of Connections 8 ports facilitate efficient topology design. With its minimal footprint, the S20-SSDI-8/4 integrates seamlessly into safety control cabinets and panel assemblies.
Performance-oriented design is evident in the module’s electrical characteristics: a Rated Current capacity of 8 A ensures stable power delivery, and an Input Current draw of approximately 3 mA per channel minimizes loading on upstream devices. The module supports conductor sizes from Wire Size 0.2 to 2.5 mm², allowing both solid and ferruled conductors to be accommodated. Constructed with durable Housing Material polyamide (PA), the enclosure withstands harsh industrial environments and resists mechanical stress. Operating reliably across an Operating Temperature Range of –20 °C to +60 °C, the module maintains consistent performance under temperature extremes. The Output Type digital input architecture delivers crisp, noise-immune signal discrimination for emergency stop buttons, light curtains, and other safety interlocks. The standardized Mounting Type DIN rail installation simplifies system build-out and supports rapid maintenance cycles.
Built for integration into complex automation systems, the S20-SSDI-8/4 module aligns with CIP Safety protocols to ensure certified, high-integrity data exchange across industrial networks. Its screw-terminal interface reduces downtime during installation and maintenance, and the narrow 12.5 mm profile maximizes cabinet density without compromising serviceability. The module’s robust design supports continuous operation in high-vibration settings and contributes to overall machine uptime. Ideal for manufacturing, process control, and machine tool safety systems, the S20-SSDI-8/4 delivers reliable, scalable performance and streamlines compliance with international functional safety standards.
