Key Features

☑️ Drop-in Type-2 expansion module to add reliable digital I/O at the machine panel
☑️ 24/16 DI/DO capacity enables compact yet scalable wiring layouts
☑️ Daisy-chain friendly alongside other A03B-0815 modules for larger panels
☑️ Protection circuitry helps safeguard field wiring and downstream devices

✅ Confirmed Compatibility

✔️ Fanuc i-Series CNC controls that use A03B-0815 external I/O at the connection panel (e.g., 16i / 18i / 21i families)
✔️ Fanuc 0i-D / 0i-F control generations outfitted for A03B-0815 external I/O modules
✔️ Fanuc 30i / 31i / 32i-class machines where the builder specifies A03B-0815 modules at the connector panel
Compatibility depends on the machine builder’s wiring and the connector panel/backplane in the control cabinet. Verify your panel/connector board supports the A03B-0815 Type-2 module.
