Emerson VE4001S2T1B2 | Series 2 16-Channel Input Module

Product Description

The Emerson VE4001S2T1B2 (KJ3206X1-BA1) is a 16-channel isolated digital input module for DeltaV™ Series 2 distributed control systems (DCS). It monitors binary signals from devices such as pushbuttons, limit switches, and proximity sensors.

Moreover, each input channel features optical isolation, providing robust protection against electrical noise and ensuring safe signal acquisition. In addition, the module supports configurable response times, allowing flexible adaptation to different industrial applications.

The VE4001S2T1B2 incorporates advanced diagnostics to detect open circuits, short circuits, and module faults, enabling predictive maintenance and minimizing downtime. Its rugged construction meets hazardous area certifications (ATEX, IECEx, FM), making it suitable for oil & gas, chemical, power, and manufacturing industries.
