The Emerson VE4001S4T1B1 is a DeltaV Series 2 discrete input module designed for reliable acquisition of high-voltage AC digital signals in industrial automation systems. It is commonly used to monitor ON/OFF status from field devices such as relays, switches, limit contacts, breaker auxiliaries, and alarm circuits operating in 230 V AC environments.
Built for harsh electrical conditions, this module provides strong isolation, stable signal detection, and robust diagnostics, making it suitable for power-intensive industrial applications where high-voltage discrete signals are still widely used.
