INTRODUCTION
The M-7046 is a 15-channel Digital Input module. Each channel features photocoupler isolation and can be used as a 16-bit counter. In addition, the Digital Input type can be selected as either sink or source via wire connections. The M-7046D module includes 15 LED indicators that can be used to monitor the status of the DI channels. 8 kV ESD protection and 5000 VDC intra-module isolation are also provided to enhance noise protection capabilities in industrial environments, making the M-7046(D) module an ideal solution for Digital Input applications.
