The Emerson VE4001S3T2B2 is a DeltaV Series 2 discrete input module designed for high-reliability acquisition of 120 V AC digital field signals in industrial automation systems. It is commonly used to monitor ON/OFF status signals from switches, relays, limit devices, alarms, and control circuit contacts in power-intensive or legacy industrial environments.
This module is engineered for robust signal conditioning, electrical isolation, and stable operation under electrical noise conditions, making it suitable for demanding process industries where high-voltage discrete signals are still widely used.
