ABB NWIO-01 – 24 V DC, 1 DI Heartbeat + Relay DO, -20 °C to +60 °C, IP20

Application ScenariosOn a 180 MW biomass-fired unit’s balance-of-plant (BOP) skid—condensate-polishing + CW-pump + heater-drain—the Net 90 rack runs an NMFC03 handling eight PIDs and the motor-protect interlocks. During a lightning-strike event 18 months prior, the NMFC had entered a “scan-frozen” state where the outputs held last-value (safe, by design) but the PID stopped executing—the BOP…
