Voltage level, logic’1’ PNP ................................................................................................... >20 V DC
Nominal input current at 24 V ........................................................................................... 50 mA rms
Nominal input current at 20 V ........................................................................................... 60 mA rms
Input capacitance .................................................................................................................. 400 nF
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 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.
4) FC 302 and FC 301 A1with Safe Stop only.
