02 / FUNCTIONAL DESCRIPTION
Signal or Power Role in the Installed System
|
| FUNCTIONAL PATH | The module receives safety-logic commands and switches external 24 V DC loads through eight output channels. Its long-distance execution is used where field wiring and load conditions require the L variant. Permissible load current depends on ambient temperature and the number of energized channels, so application loading must be checked as a complete thermal case. |
