5 General Specifications
Safe stop Terminal 37 3) (Terminal 37 is fixed PNP logic):
Voltage level
Voltage level, logic'0' PNP
Voltage level, logic'1' PNP
Nominal input current at 24 V
Nominal input current at 20 V
Input capacitance
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 can only be used as safe stop input. Terminal 37 is suitable for category 3 installations in accordance with EN 954-1 (safe stop according
to category 0 EN 60204-1), and as required by the EU Machinery Directive 98/37/EC. Terminal 37 and the safe stop function are designed in accordance
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
