All digital inputs are galvanically isolated from the supply voltage (PELV) and other high-voltage termi-
nals.
1) Terminals 27 and 29 can also be programmed as output.
2) Except safe stop input Terminal 37.
3) Terminal 37 is only available in FC 302 and FC 301 A1 with Safe Stop. It can only be used as safe
stop input. Terminal 37 is suitable for category 3 installations according to EN 954-1 (safe stop according
to category 0 EN 60204-1) as required by the EU Machinery Directive 98/37/EC. Terminal 37 and the
Safe Stop function are designed in conformance with EN 60204-1, EN 50178, EN 61800-2, EN 61800-3,
and EN 954-1. For correct and safe use of the Safe Stop function follow the related information and
instructions in the Design Guide.
