2.5.1.3.3. Timeout-protection
The timeout-protection gives the possibility to switch-off automatically the
outputs on its own to prevent damage. This takes place, if in a predefined time
frame no communication with the module was possible. Reasons could be cable
disruption, PC-crash and more. This way damage control, surcharge of
connected equipment and risk of accidents can be avoided. Switching off the
outputs is indicated by a LED.
2.5.1.3.4. Plug-in connector on the module
As terminal block, user-friendly terminal strips with locking protection and
ejection mechanism are used. They are reverse-polarity protected and allow
quick replugging. The wire connection itself is realised with a screwless
connector system. A tool is included with each module.
2.5.1.3.4.1. Optocoupler-outputs (galvanically isolated, max. 2A DC)
Every output is realized using high current optocouplers. Using optocouplers
provides a secure galvanical decoupling of the module-driven equipment to the
module itself.
Pay attention to the optocoupler’s output polarity while wiring (see figure below)!
