Product Description:

The Bosch Rexroth Indramat S20-EC-BK is an emergency stop button, being part of the IndraControl series of modules S20 that are used in industrial automation.

This is an emergency stop unit with a 1NO (normally open) contact type, with a rating of 250V AC and 10A. This device is very suitable for halting control acts in an emergency. It has an actuator that is controlled through a pushlock mechanism with a turn reset that causes logical and safe engagement and reset of the emergency stop function. The S20-EC-BK is designed to be panel mounted and can be used in the standard cutout 22mm design. This facilitates the ease of fitting the module into any large selection of control panels. The unit has a durable plastic housing that has an ingress protection rating of IP65, which allows effective sealing of dust and water, making it useful in tough industrial environments. The screw terminal connection provides a safe, solid electrical bonding connection to be used long term.

Diagnostic and communication interfaces embedded in this module consist of two RJ45 Ethernet ports, a Micro USB service port, and rotary switches that allow simple network addressing. This aspect qualifies it to fit in the current industrial networks with an upgrade of system visibility and maintainability. The unit is compact with a weight of about 177 grams (including connector and bus base module) and hence easy to handle. Operating within an ambient temperature range of -25°C to +60°C, and may be safely stored between -40°C to +85°C. The product also meets any industry standards of vibration and shock, with 5g (EN 60068-2-6) and 30g (EN 60068-2-27) ratings.
