ABB Analog input option board. 2 AI: U, I. 12 Bit. Spring terminals included (TA5120-2AI-UI)

Why Choose the ABB TA5120-2AI-UI Analogue Input Option Board?

The ABB TA5120-2AI-UI is a compact analogue input option board designed to expand the analogue measurement capability of compatible ABB AC500-eCo programmable logic controllers. It provides two configurable analogue inputs for voltage or current signals, allowing industrial sensors and transmitters to be integrated directly into an AC500-eCo automation system.

Designed for the ABB AC500-eCo automation platform, the TA5120-2AI-UI supports 0–10 V and 0–20 mA analogue signals with 12-bit resolution including sign. The two inputs, identified as I0 and I1, form a single group and can be configured individually to suit the connected field instrumentation.

The TA5120-2AI-UI features galvanic isolation and two yellow status LEDs for the analogue input channels. A removable 6-pin spring terminal block with 3.50 mm pitch is supplied with the option board, providing a compact and practical solution for adding analogue process measurement to compatible AC500-eCo PLC installations.

Accurate Analogue Measurement for AC500-eCo PLCs

Analogue input option boards allow PLC systems to measure continuously varying process signals rather than simply detecting digital on/off states. The ABB TA5120-2AI-UI provides two configurable channels for acquiring voltage or current signals from industrial instrumentation, enabling physical variables such as pressure, level, flow, position and speed to be incorporated into PLC control logic.

Each channel can be configured for the required voltage or current signal type within the supported measuring ranges. With 12-bit resolution, galvanic isolation and diagnostic functionality available through the AC500-eCo system, the TA5120-2AI-UI provides a compact solution for applications requiring additional analogue measurements without installing a separate external I/O module.

Typical Applications

• Pressure, level and flow measurement.
• Industrial sensor and transmitter integration.
• Machine monitoring and process control.
• Pumps, fans and water management equipment.
• HVAC and building automation systems.
• Packaging and production machinery.
• Conveyors and material handling equipment.
• OEM control panels using ABB AC500-eCo PLCs.
