Discrete Input Module GE Fanuc | IC670MDL643

GE Fanuc IC670MDL643 DC Input Module

The IC670MDL643 is a low-voltage DC input module for precise control tasks. It handles both 5V and 12V DC systems and supports positive and negative logic. This 16-point module from GE Fanuc is designed for Field Control applications requiring accurate signal reading.

Key Features

• 16 discrete input points in 2 groups
• Dual voltage support (5V/12V DC)
• Both positive and negative logic operation
• Individual LED indicators for each point
• Group-to-group isolation for safety
• Compact design weighing only 2 pounds

Technical Specifications

• Part Number: IC670MDL643
• Input Points: 16 points, 2 groups
• Rated Voltage: 5/12V DC
• Voltage Range: 0-15V DC
• Input Current: 5 mA at 5V, 16 mA at 15V
• Input Impedance: 1K Ohms typical
• Power Draw: 80 mA from bus
• On Voltage (Positive): +3.6V to +15V

Electrical Characteristics

The module operates with low voltage signals. Positive logic requires +3.6V to +15V to activate. Negative logic needs -3.6V to -15V. The off-state range is 0 to ±1.6V for both logic types. The 1K Ohm impedance ensures stable operation.

Design & Operation

This module features clear LED indicators for every input point. The transparent top cover allows easy status monitoring. It uses capacitors, diodes, and resistors for signal filtering. The terminal block accepts #14 to #22 AWG wires for flexible installation.
