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 in-
5
stallations 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 and instructions
in the Design Guide.
