Basic device ESM-BA2.., 2 safety contacts, cat. 4

The outputs are electrically decoupled and of redundant design.

By using suitable wiring, the following functions can be selected:

Short circuit monitoring to detect short circuits between the connecting cables and to shut down the outputs or prevent relay starting if necessary

Earth fault/ground fault monitoring to detect short circuits between the connecting cables and earth or ground and to shut down the outputs or prevent relay starting if necessary.

Optionally, the ESM-BA... devices are also available as version with plug-in connection terminals.
