Description
Application Scenarios
At a municipal wastewater treatment plant in Sweden,operators struggled with frequent I/O failures due to moisture ingress and poor signal isolation in their legacy control system.Downtime during pump sequencing and valve control was common,leading to overflow risks.The facility upgraded to ABB 3ASC25H209 DATX110 terminal boards within their AC 800M DCS architecture.The ABB 3ASC25H209 DATX110’s superior galvanic isolation and sealed terminal design eliminated ground loop issues and moisture-related faults.Its 16-channel DI/DO capability allowed consolidation of pump status monitoring and motor start/stop commands into a single module.After deployment,unplanned outages dropped by 75%,and maintenance staff reported a 40%reduction in troubleshooting time thanks to the clear LED indicators on each ABB 3ASC25H209 DATX110.This case underscores how the ABB 3ASC25H209 DATX110 transforms unreliable field connectivity into a robust,future-proof control layer.
