Input Characteristic Curve for Digital Inputs
IEC 61131, Type 1 in the Case of the Digital Input Module (6ES7421-1BL01-0AA0)
The input current in the case of the digital input module (6ES7421-1BL01-0AA0)
reaches 1.5 mA only above the +5 V switching threshold but under the switching
threshold of the module (typ. 9.5 V). Therefore only type 1 can be specified with the
IEC 61131 standard.
