All digital inputs are galvanically isolated from the supply voltage (PELV) and other high-voltage terminals.
1) Terminals 27 and 29 can also b e programme d as output.
2) Exc ept safe stop input Terminal 37.
3) Terminal 37 is only availa ble in FC 302 and FC 301 A1 with Safe Stop. It can only be used a s safe stop input.
Terminal 37 is suitable for category 3 installations a ccording 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 602 04-1, EN 50178, EN 61800-2, EN 61800-3 , and EN 9 54-1. For correc
t
and safe use of the Safe Stop function follo w the related information and instructions in the Design Guide.
4) FC 302 and FC 301 A1with Safe Stop only.
