M-7046/M-7046D
15-channel Isolated Digital Input Module

~ NEW ~

Model: M-7046	Model: M-7046D


Sink- or Source-type Digital Input Photocouple Isolation All Channels can be used as 16-bit Counters ±8 kV ESD Protection ±4 kV EFT Protection ±3 kV Surge Protection 5000 VDC Isolation Voltage Dual Watchdog Wide Operating Temperature Range: -25 to +75°C

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.
