Harmony IO(part No. YPHBAIN22010000, P-HB-AIN-22010000) Analog Input Module, 16 AI 4-20mA, -10 to 10 Vdc, -100 to 100 mV dc, TC (type B, E, J, K, L, N, R, S, T, U, Chinese E, S)
The Bailey Controls AIN 220 (part number P-HB-AIN-22010000) is an analog input base module used in the ABB Bailey Infi 90 and Harmony distributed control systems (DCS). It processes real-world process signals from field sensors like thermocouples, pressure transmitters, and flow meters.
Core Functionality
- Signal Versatility: Capable of processing isolated current, high-level/low-level voltage, and thermocouple signals.
- System Integration: Serves as a Harmony Block I/O component that interfaces directly with Bailey processor modules to translate field data into digital signals for system controllers.
- Termination Base: Usually supplied as a block module with an accompanying termination base (often the AIN220C100), which allows for secure and permanent field wiring.
