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 2006/42/EC installations according to
EN 954-1,PL d acc. EN ISO 13849-1 and SIL 2 acc. EN 62061 (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 61800-5-2, EN 62061, EN ISO 1384 and EN 954-1. For correct and safe use of the Safe Stop function follow the related
information and instructions in the VLT AutomationDrive Design Guide, MG33BXYY.
