Product Description:
Bosch Rexroth manufactures the S20-DO-8/2-2A control module for automation machines with 8 digital outputs. Its each output channel possesses a nominal 24 V DC signal and carries a current of 2 A, with an overall 16 A maximum output current capacity. This module offers push-in spring connectors for wiring and it is enclosed in a light grey IP20 protective case.
The S20-DO-8/2-2A control module features terminals of 8 mm strip length to fit implantation and the terminals are provided with their specific ground points. Its output signal delay at all states is 150 ms and the switching frequency of ohmic loads is able to attain 3000 Hz while on inductive loads the switching is restricted to 1 Hz. The outputs have resistances of 10 k? and all the internal sections are isolated at 500 V AC. The S20-DO-8/2-2A module provides protection against short circuit and overload, when the load is above 2.8 A. It supports web-configurable fault reporting via FF8Fhex object and also the output behavior of substitute can be set using FF8Dhex. The panel LED confirms presence of supply voltage for output channels, E1 LED indicates output faults including short-circuit and overload. This S20-DO-8/2-2A module provides local bus communication of 100 Mbit/s speed. It draws a maximum of 150 mA and consumes up to 480 W under full load operation.
The S20-DO-8/2-2A control module is able to use altitude of up to 3000 m and it can tolerate 30 g of shock resistant while the standard resistance to vibration is up to 5 g. It has a small dimension of 35 mm width, 126.1 mm height and depth of 54 mm. With connectors and base included, the total S20-DO-8/2-2A module weight adds up to 136 grams.
Frequently Asked Questions about S20-DO-8/2-2A:
Q: How does the 500 V AC isolation in the S20-DO-8/2-2A module enhance safety?
A: It ensures separation between internal circuits and field outputs, reducing the risk of electrical interference or faults impacting the entire system.
Q: Why is a 10 k? output resistance used in the S20-DO-8/2-2A module?
A: This resistance provides internal leakage protection and helps stabilize output signals under variable load conditions.
Q: How does the 8 mm strip length terminal benefit wiring tasks?
A: It ensures secure connections with minimal exposed conductor, reducing the risk of accidental shorts or loose contacts.
Q: What is the advantage of using push-in spring connectors in the S20-DO-8/2-2A?
A: Push-in spring connectors allow tool-free, vibration-resistant wiring, enhancing installation speed and reliability in automated panels.
Q: Why is the 100 Mbit/s local bus communication important in the S20-DO-8/2-2A module?
A: It provides rapid data transfer for real-time output control, essential in high-speed automation systems.
