All digital inputs are galvanically isolated from the supply voltage (PELV) and other high-voltage terminals.
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 the FC 302. 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.
4) FC 302 only.
