Core Functions

1. Bipolar analog signal expansion: Adds extra bipolar analog input and analog output channels for compatible ABB ACS580 drives. Supports positive‑negative bipolar signal ranges (‑10 V … +10 V), unipolar 0‑10 V analog signals for field instrument connectionup.
2. Analog input (AI): Receives analog measurement signals from transmitters, potentiometers, process sensors; converts external analog field signals into digital values for the drive control unit to process speed, torque or reference setpoints.More products: www.plcva.com

ABB CBAI‑01 Bipolar Analog I/O Extension Module

1. Analog output (AO): Converts drive internal operating parameters (output frequency, motor current, torque, power) into standardized analog voltage signals for external meters, recorders, PLC analog acquisition ports.
2. Side‑mount mechanical interface: Plugs onto the side of ACS580 drive control unit, no extra chassis required; status LED provides real‑time module health diagnostic indication.
3. Parameter mapping: Channels are fully configurable via drive firmware parameters; each AI/AO channel can be assigned to different drive functions for reference input or process‑value output.

Applications & Use Cases

This extension module is designed for ABB ACS580 variable‑frequency drives, used when the built‑in analog I/O terminals of the main drive are insufficient for site requirements.plcva.com

ABB CBAI‑01 Bipolar Analog I/O Extension Module

1. Industrial process control: Pump and fan variable‑speed control systems, requiring multiple bipolar analog setpoint inputs and multi‑channel analog monitoring outputs.
2. Factory automation machinery: Conveyors, mixers, extruders, packaging equipment; connect multi‑group process transmitters and local analog display instruments.
3. Building HVAC systems: Large‑scale heating, ventilation and air‑conditioning installations; receive sensor analog feedback and send drive operating status to building automation systems.
4. Retrofit & upgrade projects: Existing ACS580 drive system renovation, expand analog signal interfaces without replacing the whole frequency converter.
5. Integration with upper‑level PLC/DCS: Provide additional analog signal interconnection points between variable‑frequency drive and central automation control system.
