:
Terminal 37 is fixed PNP logic
Voltage level .................................................................................................................. 0 -24VDC
Voltage level, logic’0’ PNP .................................................................................................... < 4 V DC
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-volt
age terminals.
1) Terminals 27 and 29 can also b e programmed as output.
2) Exc ept 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 suit
able
for categ ory 3 installations according to EN 954-1 (safe stop according to category 0 EN 60204-1) as
required by the EU Ma chinery Directive 9 8/3 7/EC. Terminal 37 and the Safe Stop function are designed in
conformance with EN 60204-1, E N 50178, EN 61800-2, EN 61800-3, and EN 954 -1. For correc
tandsafe
use of the Safe Stop function, follow the related information and instructions in the Design Guide.
4) FC 302 only.
