Product Description:
Bosch Rexroth Indramat produces the S20-DI-16/1-HS digital input module for the S20 IndraControl Modules series. As a 16-channel, high-speed input device, it captures discrete sensor states and forwards them over the S20 local bus so that PLCs can react to machine events with minimal latency. The module serves decentralized control architectures, allowing field devices to be wired locally while maintaining deterministic data exchange with the central controller.
The module is designed for installation on a DIN rail, and its housing width of 35 mm keeps cabinet space usage low when multiple modules are lined up side by side. The IP20 protection class indicates that fingers and similar objects are guarded from live parts, but the unit must be mounted in an enclosure where dust or fluid exposure is possible. Logic electronics are supplied by the local bus at 5 V DC, eliminating separate power jumpers for the internal circuitry. Each input contact is rated for a maximum switching current of 8 A, a margin that supports inductive loads when surge suppression is present. The enclosure follows Housing Type 3 guidelines and provides the mechanical strength needed for installation in standard control panels.
Front wiring uses push-in terminals, allowing conductors to be inserted without tools and preventing loose screw connections during vibration. The housing has a depth of 54 mm and a height of 126.1 mm, which must be considered when arranging rows of I/O modules next to cable ducts or door braces. Continuous operation is permitted at elevations up to 3000 m above sea level, allowing the module to be used in elevated facilities such as mountain test benches or high-altitude process plants. The housing dimensions help determine the necessary clearances around adjacent equipment and wiring channels. Appropriate spacing also supports airflow through the enclosure when several S20 modules are installed together.
