Digital input module DIM76401-C1 (FAPI.421459.764-02)

The module is a functional module and is designed to measure the time characteristics of signals fed to eight single-wire discrete input channels with a common "plus" (inverse logic) and a field supply of 24 VDC. Each channel can be used as a conventional discrete input, as well as a pulse counter, pulse frequency meter, time interval meter, pulse sequence phase shift meter, quadrature counter, etc. Each channel can be used as an ordinary discrete input. Each channel of the module has hardware filtering of input signals and LED status indication. OM751, OM752 and OM753 modules can be used for input of field supply potentials. The module can be used with incremental quadrature encoders that have HTL output levels. The maximum encoder pulse frequency is 50 kHz.
