GE Fanuc IC670MDL643 Positive/Negative Logic Input Module

The GE Fanuc IC670MDL643 is a versatile logic input module. It belongs to the Field Control product series. This module accepts both positive and negative logic signals. You can use it with 5V DC or 12V DC systems. It provides sixteen discrete inputs in a compact package.

Technical Specifications of the IC670MDL643

The GE Fanuc IC670MDL643 offers sixteen (16) discrete input channels. These inputs are arranged in two groups. Each group can use positive or negative logic independently. The rated voltage is 5/12 Volts DC. The input voltage range spans 0 to 15 Volts DC. This wide range accommodates many logic families.

Logic Voltage and Current Details

For positive logic, the GE Fanuc IC670MDL643 requires +3.6V DC to +15V DC for on-state. The off-state voltage for positive logic is 0 to +1.6V DC. For negative logic, on-state requires -3.6V DC to -15V DC. The off-state for negative logic is 0 to -1.6V DC. User input current is 5 mA at 5V DC. At 15V DC, the input current reaches 16 mA. The typical input impedance is 1K Ohms.

Isolation and LED Indicators

The GE Fanuc IC670MDL643 provides 150 Volts AC of group-to-group isolation. There is no point-to-point isolation available. Each input point has its own LED indicator. A separate PWR LED shows module power status. The top of the module has a transparent section. This allows easy viewing of all individual LEDs.

Power Consumption and Data Format

This module draws 80 mA from the power supply of the bus interface module. The GE Fanuc IC670MDL643 uses 2 bytes of discrete input data. The bus interface module performs intelligent processing. It then provides the input data to the host or local processor. The module includes capacitors, diodes, and resistors for input filtering.

Installation Guidelines for the IC670MDL643

The terminal block accepts wire sizes from AWG #14 to AWG #22. The GE Fanuc IC670MDL643 creates a logic one when the switch is closed. Positive or negative logic can drive the inputs as configured. The module mounts easily in a Field Control system. Ensure proper grounding for reliable operation.
