Product Description:

The S20-DO-64/1 is a slice-type output module manufactured by Bosch Rexroth Indramat as part of the S20 IndraControl Modules series. It provides a compact means of adding discrete outputs to an IndraControl automation node, translating control-level signals into field-side switching for actuators and status indicators. The module plugs directly into the S20 backplane, shares the internal local bus, and aligns mechanically with adjacent slices, allowing high channel density without increasing cabinet width.

The unit offers 64 individually driven channels that provide the digital output function, so one slice can replace several lower-density cards. Each channel can energize loads up to 8 A under steady operating conditions. Galvanic separation between the logic and load domains withstands an isolation test of 500 V AC for one minute at 50 Hz. The housing carries an IP20 rating, limiting installation to protected enclosures but eliminating the need for external sealing gaskets. Mechanical durability includes bump endurance of 10 g and vibration resistance of 5 g. Transient immunity conforms to overvoltage category II for installations on the load side of a low-voltage distribution network.

The logic electronics draw only 5 V DC from the local bus, so the slice imposes minimal power demand on the head station. Transport safety is improved by a shock resistance of 30 g. The enclosure is molded from self-extinguishing V0 plastic, supporting flame-retardant requirements inside electrical panels. Field wiring uses a push-in connection method with single-conductor technology, allowing toolless insertion of solid or ferruled leads. Protective earth is not needed because the device falls under protection class III and relies solely on the SELV supply provided by the system power distributor.
