ABB 3BDH000374R0001Official Full Name: ABB DI 724F Digital Input Module, Order Code 3BDH000374R0001
ABB DI 724F Digital Input Module, Order Code 3BDH000374R0001 Core Function: Compact 16-channel isolated digital input module designed exclusively for the ABB Freelance AC 800F distributed DCS control system. It acquires discrete 24VDC binary status signals from field sensors, limit switches, relay contacts, valve position feedbacks, and flow/temperature alarm transmitters. Each input channel features galvanic isolation to eliminate ground loop interference between field wiring and the controller backplane bus. The module converts raw field digital signals into standardized I/O bus data for PM80xF series CPU processors, provides per-channel LED status indication, and supports built-in short-circuit and overvoltage protection for field wiring faults. Primary industrial applications: chemical
