Модуль расширения WEG MOD1.00: 24 bidirectional digital inputs (NPN and PNP)

The MOD1.00 has 24 isolated digital inputs that must be excited by an external 24 Vdc source. The inputs are bidirectional, which means the input common can be connected to either the negative or the Vdc of the power supply.

Three common pins are available, one for DI1 to DI8, another for DI9 to DI16 and another for DI17 to DI24, thus allowing a group to be connected to V+ and the other to the GND. This feature gives more flexibility to the project, since it allows both PNP and NPN contacts of a device to be connected to the MOD1.00 inputs.

The input activation levels are 10 to 28.8 Vdc for high level and below 3 Vdc for low level.
