IC660ELB922: A Genius I/O PC Interface with Two Independent Channels
The IC660ELB922 is a PC interface module for the Genius I/O system, and the two-channel dual-daughterboard arrangement is what defines it. Two independent channels means two separate Genius I/O buses can be brought back to a single PC — which is how a Genius I/O installation is supervised when the original Genius Bus controller is no longer the primary interface.
It is a single-slot AT-style board, drawing 5 VDC at 400 mA with a bus loading of 1 LS TTL load per input line and bus drive capability of 10 LS TTL loads per output line.

Genius I/O Electronics and Interface Modules
Genius I/O racks share the electronics assembly across block types, and the interface modules are separate from the measurement blocks. Confirming which role a board fills before ordering avoids a module that installs but does not interface:
| IC660 Part Number | Interface / Electronics Function |
|---|---|
| IC660EBA020 | Genius I/O interface or electronics assembly — confirm the role against the rack |
| IC660EBA021 | Genius I/O interface or electronics assembly — confirm the role against the rack |
| IC660EBA023 | Genius I/O interface or electronics assembly — confirm the role against the rack |
| IC660EBA024 | Genius I/O interface or electronics assembly — confirm the role against the rack |
| IC660EBA025 | Genius I/O interface or electronics assembly — confirm the role against the rack |
| IC660EBA026 | Genius I/O interface or electronics assembly — confirm the role against the rack |
| IC660EBA027 | Genius I/O interface or electronics assembly — confirm the role against the rack |
| IC660EBA100 | Genius I/O interface or electronics assembly — confirm the role against the rack |
| IC660EBA101 | Genius I/O interface or electronics assembly — confirm the role against the rack |
| IC660EBA103 | Genius I/O interface or electronics assembly — confirm the role against the rack |
Bus Loading Constrains Rack Population
Bus loading of 1 LS TTL load per input line is the number that limits how much can be attached. Genius I/O backplanes have a finite load budget, and a design that adds blocks without checking cumulative loading produces intermittent communication faults rather than a clean failure at installation.
Where a PC interface replaces a Genius Bus controller in an existing rack, the load already on the bus is whatever the installed blocks consume — which is worth measuring before adding channels to the interface.
Why the AT Form Factor Matters
The AT-style single-slot form factor is what makes this board usable in a PC context. Confirming the form factor against the machine it is being installed in matters, because the slot mechanical and connector layout differ from the PLC-oriented modules in the same family.
