ABB 87TS01-1551 GJR2368900R1551 Coupling Module

Product Overview

The ABB 87TS01-1551 is a mission-critical coupling module engineered for the Advant MOD 300 and Advant OCS distributed control systems (DCS). Its primary role is to serve as a high-integrity interface between different subsystems, ensuring that data and control signals are transmitted accurately while providing a robust electrical barrier. Technical Specifications

• Operating Voltage: 24 V DC

• Power Consumption: < 3 W

• Isolation Method: Optical or transformer coupling (model-variant dependent)

• Dimensions: 290 × 130 × 35 mm

• Weight: 0.5 kg

• Operating Temperature: 0 °C to +55 °C (32 °F to 131 °F)

• Humidity: 5% to 95%, non-condensing

• Compatibility: ABB Advant MOD 300, Advant OCS, and Bailey INFI 90 platforms

Key Features

• Superior Galvanic Isolation: Effectively separates electrical potentials between subsystems, neutralizing ground potential mismatches that can otherwise cause signal distortion or hardware damage.

• Advanced Surge Protection: Acts as a defensive shield for critical control units, absorbing voltage spikes and surges before they can reach the central processing components.

• EMI/RFI Resilience: Specifically designed to maintain signal integrity in "noisy" industrial environments where high-voltage cables and heavy machinery generate significant electromagnetic interference.

• Simplified Integration: The plug-in rack design and clearly marked terminals allow for rapid installation and hot-swappable maintenance in supported configurations.

• Long-Term Reliability: Built with industrial-grade components rated for continuous duty in the high-heat, high-humidity conditions common in chemical and power plants.
