Product Overview
When high-power Signal Conditioning Modules (SCMs) in your ABB Ability™ System 800xA automation platform demand reliable field power, the ABB PTB810K01 3BSE088182R1 Power Injection Terminal Block provides a cost-effective solution. Designed for the Select I/O system, this terminal block injects 24 V field power directly to high-power SCMs on the Module Termination Unit (TUS810). By delivering up to 20 A, it supports demanding digital output and high-amp SCMs such as DOS810, DOS880, DOS885, and AIS885. This eliminates the need for separate power distribution, reducing installation complexity and material costs. Each package includes 10 pieces, and two PTB810s are required per MTU, ensuring scalability for large projects.
Technical Specifications Breakdown
- Power Injection Capability: The PTB810K01 injects 24 V field power and can provide up to 20 A. This high current capacity supports multiple high-power SCMs on a single MTU, reducing the number of power supplies needed and lowering overall system cost.
- Environmental Resilience: Operating temperature ranges from -40°C to +70°C (-40°F to 158°F), with storage from -40°C to +85°C (-40°F to 185°F). This wide range ensures reliable operation in harsh industrial environments, minimizing downtime due to temperature extremes.
- Hazardous Area Certification: The terminal block is certified for use in hazardous areas with ATEX, IECEx, and cULus approvals (e.g., ATEX II 3G Ex ec IIC T4 Gc). This eliminates the need for additional enclosures or barriers in Zone 2/Division 2 locations, saving installation and maintenance costs.
- Mechanical Robustness: With IP20 protection (IEC 60529) and Pollution Degree 2 (IEC 60664-1), the PTB810K01 withstands typical industrial contaminants. Its compact dimensions (41.4 mm width, 72.6 mm depth, 19.2 mm height) and light weight (38 g) simplify mounting and reduce panel space requirements.
- EMC Compliance: Meets IEC/EN 61000-6-4 (emission) and IEC/EN 61000-6-2 (immunity) standards, ensuring stable operation in electrically noisy environments and reducing the risk of signal interference.
Industry Applications
- Process Automation (Oil & Gas): In refineries and chemical plants, the PTB810K01 powers high-amp SCMs monitoring critical pressure and temperature loops. Its hazardous area certifications (ATEX, IECEx) allow direct installation in Zone 2 areas, eliminating the cost of explosion-proof enclosures and simplifying maintenance.
- Power Generation: For turbine control systems requiring high-reliability digital outputs, the PTB810K01 injects 24 V power to DOS885 modules. The 20 A capacity supports multiple actuators, reducing the number of power injection points and associated wiring costs.
- Marine Applications: With DNV and ABS marine certifications, the terminal block suits offshore platforms and shipboard automation. Its corrosion resistance (G3 corrosive atmosphere) and wide temperature range ensure long service life in salt-laden environments, lowering total cost of ownership.
Installation & Setup Guidance
Mount the PTB810K01 directly onto the TUS810 Module Termination Unit. Use the four screws for daisy-chaining power supply connections to adjacent terminal blocks, simplifying wiring and reducing installation time. Each terminal includes a hole for connecting test probes, enabling easy voltage measurements during commissioning without disconnecting wires. Ensure the MTU is powered off during installation to prevent electrical hazards. For hazardous area installations, follow local regulations and the product’s ATEX/IECEx installation instructions.
Maintenance & Reliability
Regular inspection of the PTB810K01 is minimal due to its robust design. Periodically check for signs of corrosion or mechanical damage, especially in high-humidity or corrosive environments (G3 classification). The IP20 rating protects against dust ingress but requires the terminal block to be installed in a suitable enclosure. By using the PTB810K01, you reduce the number of discrete power distribution components, which lowers potential failure points and maintenance costs over the system’s lifecycle.
Compatibility & Integration
The PTB810K01 is designed exclusively for the ABB Select I/O system within the ABB Ability™ System 800xA platform. It integrates seamlessly with the TUS810 Module Termination Unit and works with digital output SCMs (DOS810, DOS880, DOS885) and high-amp SCMs (DOS885, AIS885). The daisy-chain capability allows multiple PTB810s to share a single power feed, reducing wiring complexity. No additional communication protocols are required; the terminal block operates purely as a power distribution device.
Selection Guide & Purchasing Advice
Before purchasing, verify that your system uses Select I/O modules requiring 24 V field power injection. Each MTU requires two PTB810K01 units. Confirm compatibility with your specific SCM models (DOS810, DOS880, DOS885, AIS885). The package contains 10 pieces, suitable for multiple MTUs.
