Connecting the inputs The easySafety device is provided only with safety outputs.
For safety applications, the IS safety inputs must be read in
the safety circuit diagram, processed and output exclusively
with the QR output (redundant relay output) or one of the QS
outputs (safety transistor/relay outputs).
The inputs of the easySafety devices switch electronically.
Once you have connected a contact via an input terminal,
you can reuse it as a switching contact in the safety and
standard circuit diagram as often as you like.
When using special function blocks, certain inputs are
permanently assigned to these function blocks and cannot
be used for any other purpose. The relevant function block
description describes which inputs are affected.
Example: “Overspeed monitoring” safety function block, for
which the device inputs IS1 and IS2 are connected directly.

Connect the contacts, for example buttons or switches, to
the input terminals of the easySafety device.
