About the 8005-DN-108
The 8005-DN-108 is a 24 VDC 8 Function Input Module that was created by Square-D. This module is a part of the Schneider Electric product line but is no longer supported. It may be a little hard to locate, but AX Control still tries to keep this module stocked.
The 8005-DN-108 has a total of 8 optically isolated inputs with one common connection per 8 points. These are compatible with PNP-output sensors. It is classified as a sink type model. It has a rated input of 24 VDC. It has an input voltage of 10VDC to 30VDC. It has an input current of 10 mA/ points at 24VDC. it has an input impedance of 2.3K ohms. It has a 7 millisecond maximum turn on time and an 11 millisecond maximum turn off time. It needs a 10 VDC must turn on voltage and a 3 VDC turn off voltage. It has a 4.10mA at 10 VDC turn on current and a 0.98mA at 3 VDC turn off current. This module has a 20mA maximum internal current draw. It has a photocoupler isolation mode of 1500V RMS/1 minute.
This module has an LED input indication. There are 8 LEDs total that are numerically labeled 0-7. These LEDs light up when there is a connection to the correspondingly labeled terminal I/O strip. There are two additional terminal screw connections that are labeled NC and com (-). The NC label means that the user should not connect an input or any other type of wiring to this terminal screw.
