EMERSON 396571-02-6 Digital Input Module

Product Overview

The EMERSON 396571-02-6 is a digital input (DI) module designed for industrial automation and control systems, particularly compatible with Bristol Babcock (now part of Emerson) control systems. It is used for signal acquisition from digital sensors, switches, and relays, providing reliable 24V DC wet/dry contact input processing for DCS (Distributed Control Systems) and PLC applications .

Key Features & Technical Specifications

1. Input Configuration

• Input Type: 24V DC wet/dry contact (compatible with NPN/PNP sensors) .

• Isolation: Optical isolation between field inputs and system logic (prevents ground loops) .

• Filtering: Built-in noise suppression for stable signal acquisition .

2. Electrical & Environmental Specs

• Input Voltage Range: 12–24V DC (nominal) .

• Operating Temperature: -25°C to +60°C (industrial-grade) .

• Protection Rating: IP20 (dust-resistant, for panel mounting) .

3. Compatibility & Integration

• System Compatibility: Designed for Bristol Babcock/Emerson DCS/PLC systems .

• Mounting: DIN rail or panel-mounted (modular design) .

4. Certifications

• CE, ATEX (Zone 2), UL compliant for industrial safety .

Applications

1. Process Automation:

   • Signal acquisition in refineries, chemical plants, and power generation .

2. Machine Control:

   • Monitoring limit switches, push buttons, and proximity sensors .

3. Safety Systems:

   • Integration into emergency shutdown (ESD) circuits .

Installation & Usage Notes

1. Wiring:

   • Use shielded cables for noise immunity .

   • Verify polarity for wet contact inputs (if applicable) .

2. Maintenance:

   • Regularly check LED status indicators for fault diagnostics .

3. Compatibility:

   • Confirm integration with Emerson/Bristol Babcock controllers (e.g., ControlWave Micro) .
