Emerson VE4001S2T2B2 Discrete Input Module

Overview

The Emerson VE4001S2T2B2 is an 8-channel discrete input module designed for DeltaV™ Distributed Control Systems. It supports 24 VDC dry contact inputs, making it ideal for detecting digital signals from push buttons, limit switches, and relay contacts. The module features a fused I/O termination block for enhanced protection and includes optical isolation for each channel. Thanks to its rugged design and wide temperature range, it operates reliably in harsh industrial environments.
