Product Description:
The S20-DO-16/3 digital output module belongs to the S20 IndraControl Modules series produced by Bosch Rexroth Indramat. Intended for decentralized machine architectures, the module attaches to an S20 backplane and converts controller commands into switched power for as many as sixteen field actuators. Its compact, channel-dense design simplifies the wiring of solenoids, contactors, and indicator devices in automated production cells. The module’s narrow form also allows multiple output slices to be arranged together inside a control cabinet while maintaining organized connections to field equipment.
On the supply side, the module accepts a nominal 24 V DC feed and tolerates supply ripple of ±5%, allowing stable operation during minor voltage fluctuations. Each channel can conduct up to 8 A, supporting the inductive and resistive loads used in material-handling and assembly processes. Backplane communication reaches 100 Mbps, providing rapid data exchange between the station controller and the output drivers. The internal logic domain is powered by an isolated 5 V DC rail, which helps maintain signal integrity between the control electronics and field circuits. Field conductors are secured by a push-in connection system that eliminates the need to tighten screws and supports efficient wire installation. The housing has an IP20 protection rating, so the module must be installed inside an enclosed panel that limits access to its electrical components.
The enclosure is made from V0-classified plastic with self-extinguishing properties and uses a wide, two-terminal-field layout that provides space for organized cable routing. The housing measures 53.6 mm wide, 129.9 mm high, and 54 mm deep, permitting dense row mounting on a DIN rail without obstructing adjacent modules. Its plastic enclosure also reduces the risk of conductive contact around the internal electronics. Electrical insulation meets protection class III requirements, indicating that protection against electric shock relies on safety extra-low voltage and that hazardous supply voltages are not generated within the module. The unit is assigned to overvoltage category II, making it suitable for circuits in which transient energy is limited by the upstream electrical installation. Proper conductor sizing and adequate cabinet ventilation remain necessary for managing channel loads and heat during continuous operation.
