S20-DI-16/1

The S20-DI-16/1 input module from the S20 IndraControl Modules series by Bosch Rexroth Indramat delivers robust digital signal acquisition optimized for modern industrial automation. This compact unit features 16 inputs accommodating both digital sink or source inputs and operates at a nominal input voltage of 24 V DC within a broader input voltage range of 15 V DC ... 30 V DC. With a module width of 53.6 mm and weight of only 0.19 kg, it preserves valuable rack space while simplifying system expansion. The design incorporates a configurable input filter of 3 ms typical to suppress signal noise, ensuring clean transitions and reliable detection. Rated for operation between –20 °C and +60 °C ambient temperature, the S20-DI-16/1 maintains consistent performance across a wide thermal envelope. An integral LED status indicator per channel provides immediate visual feedback on input states and diagnostics.

Performance characteristics are engineered for high-speed, low-latency digital processing. Each channel draws typically 2.5 mA per channel, resulting in a modest maximum power dissipation of 0.8 W for the entire module, which minimizes heat buildup in densely populated I/O racks. The push-in connection method supports rapid conductor insertion without tools and promotes secure termination even under vibration. Thanks to the 1-wire connectivity topology, installation complexity is reduced by requiring only one conductor per input, which streamlines wiring effort and lowers system costs. The module’s IP20 protection class and rugged construction uphold signal integrity in industrial environments, while CE and cULus listed approvals certify compliance with global safety and EMC standards. Real-time data flow between the controller and peripherals is ensured by the module’s fast signal scanning, facilitating immediate response in critical automation tasks.

Built for seamless integration into control cabinets, the S20-DI-16/1 mounts effortlessly on a standard DIN rail mounting system, enabling quick deployment alongside other S20 modules. The IP20-rated housing and robust connection technology deliver dependable operation in applications subject to mechanical stress or electrical interference. Its broad temperature rating and international certifications underpin system availability in manufacturing, packaging, material handling, and process control. Reliability is further enhanced through built-in diagnostics and clear LED indicators that simplify troubleshooting and reduce downtime. This versatile module is ideal for expanding digital I/O capacity in complex automation networks where precision, durability, and ease of integration are paramount.
