The ABB 500AIM02 (order code: 1MRB150022R0002) is an 8‑channel differential analog input module designed for ABB AC500 series PLC/DCS, optimized for high‑precision acquisition of industrial process signals (temperature, pressure, flow, level). As a variant of the 500AIM02 base model (1MRB150022R001), it retains identical core specs—16‑bit ADC, channel‑to‑channel isolation (2.5kV), ABB FBP (Flexible Bus Protocol) integration—with minor batch/component variations for supply chain flexibility. It features IP20 front protection, -20°C to +70°C operation, surge protection, EMC filtering, and isolated sensor excitation, ensuring stable performance in harsh industrial sites (chemical plants, power stations, manufacturing lines).
