GE Fanuc Series 90-30 IC693MDL655 24VDC 32-Point Discrete Input Module

Detailed Technical Specifications

The following performance data defines the electrical and operational boundaries for the IC693MDL655 input card:

• Input Channels: 32 discrete points organized into four isolated groups of eight

• Voltage Rating: 24 VDC nominal (acceptable operating range of 0 to 30 VDC)

• Input Logic: Positive/Negative (Sink or Source) compatible

• On-State Voltage: 11.5 VDC to 30.0 VDC

• Off-State Voltage: 0.0 VDC to 5.0 VDC

• On-State Current: 3.2 mA minimum at 11.5 VDC

• Off-State Current: 1.1 mA maximum allowable leakage

• Input Impedance: Approximately 7 mA per channel at nominal voltage

• Signal Response Time: 2 ms typical for both On and Off transitions

• Internal Power Consumption: 195 mA from the 5V bus; 224 mA from the 24V relay bus on the backplane

• Wiring Interface: Front-facing terminal block (compatible with standard 90-30 connectors)

System Integration and Application

The IC693MDL655 is frequently utilized in high-density automation environments where rack space is at a premium. By providing 32 points in a single slot, it doubles the capacity of standard 16-point modules. It is ideal for material handling systems, packaging machinery, and general sequence control. Users should ensure that the external 24VDC power supply is sized correctly to handle the aggregate current of all active inputs to maintain signal integrity.

Common Technical Inquiries

How do I configure this module for Sinking vs. Sourcing?

The logic type is determined by the external wiring of the common terminals for each group. Connecting the common to the negative rail enables positive logic (sinking), while connecting it to the positive rail enables negative logic (sourcing).

Can this module be used in a Series 90-30 Expansion Rack?

Yes, the IC693MDL655 is compatible with local, expansion, and remote VME-based racks within the Series 90-30 architecture.

What is the status of this product's lifecycle?

The Series 90-30 has been officially moved to a mature/discontinued status by the manufacturer. However, these modules remain critical for maintaining legacy installations and are widely supported through refurbished and surplus channels.
