GE FANUC IC670MDL640 Positive/Negative Discrete Input Module

Description

The GE FANUC IC670MDL640 Positive/Negative Discrete Input Module is a 16-channel digital input unit belonging to the Field Control series. Designed for industrial automation systems, its core function is to receive digital signals from external devices and convert them into signals recognizable by PLCs, serving as a critical component for controlling industrial processes and integrating into standalone controller networks.

Key technical specifications include 16 discrete input channels, an input voltage range of 0 to 30V DC, and a rated operating voltage of 24V DC. It supports flexible positive or negative logic input configurations: positive logic inputs draw current from external devices and return it to the common bus, while negative logic inputs draw current from the common bus and return it to external devices, with a logic 1 signal triggered when the switch closes regardless of logic type. Each channel has an independent LED indicator to display input status, and a dedicated power indicator shows the presence of field and backplane power.

Constructed for rugged industrial environments, it features a DIN rail mounting design for quick, easy installation. Operating parameters include a temperature range of 0 degrees Celsius to 55 degrees Celsius, relative humidity of 5% to 95% without condensation, a typical switch response time of 6 milliseconds, maximum 10 milliseconds, per-channel input current of 7.5 mA at 24V DC, typical total current draw of 75 mA, and maximum bus interface unit power draw of 83 mA. It is compatible with IC670 and IC670MDL series PLC systems.
