GE Fanuc IC610MDL158A Series One Discrete Output Module

The GE Fanuc IC610MDL158A, also cataloged as the IC610MDL158 Discrete Output Module, operates as a dedicated hardware component for discrete load switching within GE Fanuc Series One platforms. This 16-circuit module provides sourcing 24 VDC output signals from internal backplane logic states directly to external field actuators.

Suffix Breakdown & Model Matrix

• Base Model: IC610MDL158

• Module Function: 16-Circuit 24 VDC Sourcing Output Module

Hardware Specifications

Firmware Flash Compatibility and I/O Density Scaling

The IC610MDL158A interfaces directly with Series One backplane structures to handle discrete signal distribution across 16 sourcing output circuits. High-density output signal conditioning maintains rapid I/O density scaling without degrading CPU scan integrity or backplane communication velocity. Revision A board hardware ensures full firmware flash compatibility across standard Series One processor chassis, preserving deterministic output timing during heavy field load switching.

Frequently Asked Questions

Q: Does the IC610MDL158A support hot-swapping while the Series One system is running?

A: No, system power to the backplane rack must be completely turned off prior to installing or removing the IC610MDL158A to avoid electrical damage to connector contacts.

Q: How does a sourcing output module differ from a sinking output module in this series?

A: The IC610MDL158A sourcing module supplies 24 VDC current directly from the positive terminal to the load, whereas a sinking module routes current from the load to the common DC ground.

Field Installation Guidelines

1. Backplane Chassis Seating: De-energize the rack frame. Align the circuit board edges with the guide channels in the Series One slot, sliding the unit firmly until the backplane connector seats completely. Secure retention clips.
2. Field Wiring and Polarity: Wire external field devices to the removable terminal assembly, verifying that the 24 VDC power supply polarity matches the sourcing output requirements for all 16 circuits.
3. Transient Suppression and Cabling: Connect external suppression devices (flyback diodes or surge absorbers) across inductive loads, and isolate field power leads from communication cables inside the cabinet.
