The TA5128-2AI1AO (1SAP187100R0005) is an analog I/O option board for ABB's Distributed Automation PLCs. It provides two voltage inputs and one multi-purpose analog output (voltage or current) at 10-bit resolution — enough for basic process signal monitoring and simple loop control. Spring terminals are included, which speeds wiring and eliminates screw-terminal torque checks. Rated IP20, so it lives in a clean indoor cabinet; no gasket or coating for washdown zones.
