TERT*A Yokogawa High Density Distributed Control Terminal Strip

Product Overview

The Yokogawa TERT*A serves as a heavy-duty, high-density connection interface that routes raw field I/O signals directly into central I/O modules. This 16-point terminal block module integrates seamlessly across the Yokogawa FIO, CENTUM VP, and STARDOM distributed control system (DCS) architectures. By providing a rugged physical termination layer, it ensures clean, uncompromised signal transmission from field sensors, switches, and transmitters to the system backplane. Process plants deploy this hardware to simplify marshalling cabinet layouts and preserve signal accuracy across complex automation loops.

Engineering Advantages

• Approved for Hazardous Locations: Deploying standard terminal blocks into explosive atmospheres introduces severe safety risks. The TERT*A holds official CSA Non-Incendive compliance certification. This safety rating ensures the module limits electrical energy levels, preventing any arc or thermal spark from igniting volatile gases in Class I, Division 2 hazardous industrial areas.

• Eliminates High-Voltage Signal Bleedthrough: Transient voltage spikes and ground disturbances can bleed between adjacent signal lines, corrupting analog measurements and causing false control trips. The TERT*A provides a solid 500 V AC withstanding voltage barrier and an insulation resistance of 100 MOhms or greater. This rigid dielectric boundary completely insulates each of the 16 paths, maintaining high signal purity.

• Secures Large Industrial Field Conductors: Small, fragile spring clamps often fail to hold thick field wires, creating high-resistance points or loose connections under thermal expansion. This block utilizes heavy-duty M4 screw terminals. The broader thread design allows installers to apply high torque, tightly clamping ring or spade lugs directly onto the busbar to create a low-resistance, permanent connection.

• Optimizes Space Inside Marshalling Enclosures: Packing 16 fully isolated contact points onto a single, compact block footprint drastically reduces the required square footage inside crowded marshalling cabinets. This streamlined layout gives engineers more space to organize wiring ducts, improves internal air circulation, and minimizes the overall size and cost of the control enclosure.

FAQs

• Q: Is this TERT*A terminal block unit brand new and original?A: Yes. We supply this product exclusively as a 100% brand new, authentic, and original factory item from Yokogawa Japan. Every unit ships in its factory-sealed manufacturer box with matching serial numbers and quality inserts.

• Q: Does the module package include the complete terminal unit housing, or is it just the connector strip?A: The TERT*A ships as a complete, integrated terminal block module module constructed from durable industrial plastic housing, containing all 16 M4 screw termination positions ready for immediate cabinet mounting.

• Q: Can this terminal block withstand continuous condensing humidity environments?A: No. While the industrial-grade plastic shell and components operate safely across a broad relative humidity spectrum of 5 to 90 percent, you must mount the module within an appropriately sealed, weather-protected control enclosure to prevent liquid water condensation from shorting the raw M4 screw contacts.
