ABB AGBB-01C I/O Expansion Board – ACS800 8AI+2AO Analog Extension – Tested

Product Overview

Original ABB AGBB-01C analog I/O expansion board for ACS800 series drives. Plugs into the drive’s option slot to add 8 analog input channels and 2 analog output channels. Used when built-in AI/AO channels are insufficient for process control applications. 12-bit resolution with ±0.1% accuracy. Channels are galvanically isolated to suppress inverter switching noise.

Specifications

Compatibility Note

• Compatible with ACS800 series drives only
• Requires RMIO control board with X50 option slot
• NOT compatible with ACS880 series (uses NIOC/FIO extension)
• Channels default to voltage mode (-10V to +10V); for 4-20mA add external 250Ω resistors
• Verify drive model and hardware version before ordering
