FC 300 Operating Instructions
General Specifications
Input resistance, R
i
...................................................................................................... approx. 4 kΩ
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) Terminal 37 is only available in 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).
3) Exception: Terminal 37 is fixed PNP logic.
