Description
Product Introduction & Engineering Value
Large field panels become difficult to maintain when individual input and output modules are scattered throughout a machine. The GE IC660BBD024 addresses this by combining thirty-two configurable discrete I/O circuits into a single intelligent Genius I/O block located close to field devices, reducing cabinet wiring and simplifying diagnostics.
Designed for the GE Genius distributed I/O architecture, the module supports proximity switches, pushbuttons, relays, solenoids, pilot lamps, and other discrete devices. Each circuit is software configurable, allowing engineers to adapt the same hardware to changing system requirements without replacing the module.

Field Application & The “Trench” Experience
A packaging facility began experiencing intermittent conveyor stoppages during peak production. Initial troubleshooting suggested a PLC issue, but diagnostics pointed to multiple remote input faults. Engineers discovered damaged field wiring near a remote junction box. Replacing the aging remote I/O assembly with an IC660BBD024 restored stable communication while allowing every sensor and solenoid to remain on a single Genius block. Future troubleshooting became significantly faster because every circuit’s status could be viewed directly from the block LEDs and Genius diagnostics.
Typical applications include:
- Automated pallet conveyor systems
- Automotive body welding fixtures
- Chemical process valve and limit switch monitoring

The Veteran’s Tech Trap Guide
⚠️ Source vs. Sink Matters
The IC660BBD024 is a Source I/O Block. It supplies current to output devices. It is not interchangeable with the IC660BBD025 Sink Block, even though the two modules appear nearly identical. Selecting the wrong model can prevent field devices from operating correctly.
⚠️ Don’t Leave Every Circuit at the Factory Default
Each of the 32 channels must be configured for its intended function. Leaving a channel configured as an output when it should operate as an input is a common commissioning mistake that can delay startup.
PRO TIP: Before replacing an existing Genius block, upload and save the current block configuration with the Genius Hand-Held Monitor or engineering software. Restoring the saved configuration is much faster than manually reconfiguring 32 channels after installation.
Dynamic FAQ
Q1. What is the primary function of the IC660BBD024?
The is an intelligent 32-point distributed discrete I/O block that connects field devices to a GE Genius control network while allowing each circuit to operate as an input, output, or output with feedback.
Q2. Which field devices can be connected?
The module supports pushbuttons, selector switches, electronic proximity sensors, relay coils, contactors, pilot lamps, and other standard 12/24 VDC discrete devices.
Q3. Does every channel have to perform the same function?
No. Each of the 32 circuits is independently configurable, allowing mixed input and output applications within the same block.
Q4. What happens if an output is short-circuited?
The includes self-protecting output circuitry that detects overload conditions and protects the output drivers against wiring faults.
Q5. How are refurbished modules tested?
Each unit undergoes catalog verification, communication testing, functional testing of all 32 I/O channels, LED verification, terminal inspection, and electrical protection checks before shipment.
Q6. Are New Surplus units still available?
Yes. Depending on inventory, New Surplus and professionally Refurbished modules remain available to support legacy GE Genius installations, typically with warranty coverage.
