Product Introduction

The ABB 87TS01 GJR2368900R1551 Coupling Module is a key component within ABB’s robust range of control system accessories. Specifically designed for use in industrial automation and process control systems, this module provides a reliable and effective method for electrical isolation and signal coupling between different system parts. It belongs to the ABB Advant OCS / MOD 300 family, a legacy yet widely utilized distributed control system.

Designed with high reliability and durability in mind, the 87TS01 module is tailored to ensure signal integrity and protection across interfaces, especially in environments exposed to high levels of electromagnetic interference. With plug-in installation and clearly labeled terminals, it allows for seamless integration into existing control architectures.

The module also plays a pivotal role in protecting control units from overvoltage, surges, and mismatched ground potentials by using opto-isolated or transformer-coupled methods, depending on configuration.

Frequently Asked Questions (FAQ)

1. How does the ABB 87TS01 achieve electrical isolation?
   The ABB 87TS01 utilizes either opto-isolators or transformer-based coupling depending on its internal configuration. This provides galvanic isolation between control signals, minimizing the risk of ground loops and signal interference.

2. What signal types can the 87TS01 handle?
   It is designed to manage low-voltage analog and digital control signals typically used in industrial automation systems. The exact voltage and current levels depend on the specific installation, but it generally supports 24V DC logic signals.

3. Is the 87TS01 module suitable for safety-critical applications?
   Yes, while not a certified SIL-rated device on its own, it is widely used in systems that require reliable isolation in safety applications, such as turbine control, emergency shutdown systems, and substation automation.

4. Can the 87TS01 be directly interfaced with ABB PLC I/O modules?
   Yes, the module is designed to act as an intermediary between field signals and PLC/DCS I/O modules, particularly in MOD 300 and Advant OCS environments, ensuring signal integrity and protection.

5. What is the maximum number of coupling modules that can be installed in a single rack?
   This depends on the power supply capacity and the thermal limits of the rack system. Typically, a standard MOD 300 rack can host up to 16 modules, including I/O and coupling modules.

6. What kind of protection does the 87TS01 provide against electrical disturbances?
   The module includes built-in filtering and isolation components that suppress transient voltages, electromagnetic interference (EMI), and surges, providing reliable signal transmission in noisy industrial environments.

7. How do I verify the correct operation of the 87TS01 in the field?
   Field verification can be performed by monitoring signal continuity using test points or diagnostic tools on the terminal side. In systems with diagnostics support, signal integrity checks can be logged automatically.

8. Can the module operate continuously in environments with high humidity and temperature variations?
   Yes, it is rated for industrial conditions, supporting 5% to 95% non-condensing humidity and a wide temperature range of -20°C to +60°C. It is suitable for enclosed control cabinets in demanding settings.

9. How is the module grounded within the control system?
   Grounding is achieved through system chassis and via shielded cable connections to the terminal points. Proper grounding design is critical to ensure isolation performance and prevent interference.

10. Are there software configuration requirements for this module?
    No software configuration is typically needed. It functions as a passive or semi-passive device in the signal path, relying on physical wiring rather than software programming. Configuration is handled through system design and wiring schematics.
