Description

TRICON

Speed signals from rotating equipment.

Triconex 3511 is an eight-input pulse measurement module for Tricon control systems. Its non-commoned inputs accept signals across a 20–20,000 Hz frequency range with a typical update time of 25 ms. The input design is optimized for non-amplified magnetic pickups used with rotating machinery. Each input is processed through isolated channels for reliable frequency measurement. Compatible sine, square and pulse signals allow the module to receive speed-related field information. The module is intended for frequency measurement rather than pulse totalization.

04

Function

01 / Receive pickup signals

Balanced input circuitry accepts the changing electrical signal produced by a compatible magnetic speed pickup.

02 / Measure frequency

Pulse timing is converted into an input frequency value for the Tricon application to use in its configured control logic.

03 / Support online maintenance

Module diagnostics and hot-spare support allow a faulty input module to be identified and replaced in an appropriately configured system.

05

Speed Measurement & Signal Matching

Match the pickup waveform

Select a pickup whose amplitude, frequency and duty cycle remain within the input ratings throughout the required speed range.

The module is not a pulse totalizer; accumulated event counting requires a suitable alternative input function.

A

Turbine speed acquisition

Non-amplified magnetic pickups can provide rotational speed information from turbine shafts for the configured control application.

B

Compressor monitoring

Frequency inputs can receive compatible compressor speed signals without commoning the individual field input circuits.

Our Company History

2005

The Beginning

Company was founded in Xiamen, Fujian, China, in 2005 with a team of only four people. At that time, we mainly served selected European and North American markets, supplying commonly requested industrial automation products from Siemens, Allen-Bradley and Bently Nevada. Although the business was still developing and we completed relatively few orders, this period helped us build essential product knowledge and international trade experience.

2017

A Period of Growth

By 2017, our team had grown to approximately 30 people, and we had established a warehouse for in-stock automation components. Our business expanded across Europe, North America and Southeast Asia, while our product range grew from popular models to scarce and discontinued industrial automation parts. As our product knowledge and service experience increased, we completed nearly 20 orders per month on average.

Serving Customers Worldwide

Today, Company serves customers worldwide with a professional team of approximately 60 people. Our warehouse holds a broad selection of industrial automation components, including popular products, hard-to-find parts and discontinued models. We now complete more than 30 orders per month, with an average monthly transaction value of approximately USD 3 million. We have established long-term partnerships with nearly 30 customers from different countries and welcomed almost 40 international customers to visit our company.

2026Our Team Today

Since our company was founded, we have served every customer with sincerity and professionalism. Our prices may not always be the lowest, but we earn long-term trust through quality products, dependable after-sales support, honest condition reporting, timely communication and responsible delivery. Our goal is to build lasting partnerships rather than pursue one-off transactions.

07

After-Sales Support

Support across the equipment lifecycle.

01

Warranty Support

Most products are covered by a warranty of up to 12 months, subject to the applicable terms and conditions. If any product-related issue occurs during the warranty period, our team will assist you and provide an appropriate solution.

02

Technical Documentation

Relevant datasheets and technical literature can be provided with the goods, offering useful information for product identification, installation, operation, and maintenance.

03

Fast Response

We understand the importance of minimizing equipment downtime. Our team responds promptly to inquiries and provides professional assistance with product information, quotations, order status, shipping, and after-sales questions.

04

Global Customer Service

We serve customers worldwide and provide reliable assistance from inquiry to delivery and after-sales service, ensuring clear and timely communication throughout the process.

05

Long-term Spare Parts Supply

We continue to source discontinued, obsolete, and hard-to-find automation parts from various brands, helping customers maintain existing equipment and reduce downtime caused by spare parts shortages.
