Emerson VE4001S2B1 Discrete Input Card

Product Introduction

The Emerson VE4001S2B1 Discrete Input Card is an advanced I/O module designed for high-reliability control systems used in process automation and industrial environments. This discrete input card interfaces with a wide variety of on/off field devices such as limit switches, push buttons, and status contacts, providing precise digital signal acquisition for distributed control systems (DCS). Built for continuous operation in harsh conditions, it offers fast response times, secure isolation, and seamless integration into Emerson’s DeltaV™ and Ovation™ platforms. The rugged design ensures dependable performance in applications that demand uncompromising reliability and long service life.

Product Parameters

Applications

• Process Automation – Monitors valve limit switches, pump start/stop signals, and safety interlocks in chemical and petrochemical plants.

• Power Generation – Captures critical status inputs in turbine control, boiler management, and auxiliary systems.

• Oil & Gas – Interfaces with remote sensors for pipeline monitoring, drilling rigs, and production platforms.

• Water & Wastewater – Tracks pump station alarms, gate valve positions, and treatment plant equipment status.

• Manufacturing – Provides reliable on/off detection for conveyors, packaging lines, and robotic systems.

• Building Automation – Integrates with HVAC, lighting, and fire-safety systems for centralized digital monitoring.

Advantages

• High Channel Density – Sixteen isolated inputs reduce cabinet space requirements.

• Fast Signal Processing – Sub-5 ms response supports real-time control and critical safety functions.
