Why Choose the ABB TA5123-2AI-RTD Analogue Input Option Board?
The ABB TA5123-2AI-RTD is a compact RTD analogue input option board designed to extend the temperature measurement capability of compatible ABB AC500-eCo V3 programmable logic controllers. It provides two configurable RTD analogue inputs, identified as I0 and I1, for connecting resistance temperature detectors directly to the PLC.
Designed for ABB AC500-eCo V3 PM50xx CPUs, the TA5123-2AI-RTD provides 16-bit resolution including sign for precise temperature measurement. It supports commonly used industrial resistance sensors including Pt100, Pt1000 and Ni1000 RTDs, making it suitable for machinery, process equipment, HVAC systems and other applications requiring reliable temperature monitoring.
The TA5123-2AI-RTD accommodates 2-wire and 3-wire RTD measurement and features an 8-pin removable spring terminal block with 3.50 mm pitch. Two yellow LEDs provide channel status indication, while a 24 V DC process supply is connected through the UP and ZP terminals. Its compact option-board format enables temperature measurement to be added directly to compatible AC500-eCo V3 CPUs without a separate external I/O module.

Precise RTD Temperature Measurement for AC500-eCo V3 PLCs
Resistance temperature detectors measure temperature through predictable changes in electrical resistance. The ABB TA5123-2AI-RTD allows compatible AC500-eCo V3 CPUs to acquire these resistance measurements directly, providing two dedicated channels for integrating industrial temperature sensors into PLC control and monitoring applications.
Support for Pt100, Pt1000 and Ni1000 sensors makes the option board suitable for a broad range of industrial temperature measurement tasks. Its 16-bit resolution provides detailed signal conversion, while support for 3-wire measurement helps compensate for lead resistance where appropriate, improving measurement performance in industrial installations.
