Description
FAULT-TOLERANT
ANALOG OUTPUT
Tricon control systems
The Triconex 3805E TMR analog output module provides eight 4-20 mA outputs for Tricon control systems. Its 12-bit resolution and commoned-return, DC-coupled output arrangement suit current-loop field connections. Three independent channels receive processor data, vote the commanded values and select a healthy channel to drive the field outputs. Internal current loopback and reference circuits support continuous diagnostics and self-calibration. A detected channel fault is isolated while the remaining healthy circuitry maintains output operation. Hot-spare support allows a faulty module to be replaced online within a correctly configured Tricon installation.
Voted Output & Continuous Diagnostics
01 / Receive and vote
Each channel receives output data from the main processors. Voting determines the requested output, and a healthy channel is selected to drive the field.
02 / Check the current path
Independent loopback circuits check signal presence and accuracy. An internal voltage reference supports self-calibration and module health monitoring.
03 / Isolate a faulty channel
Diagnostics deactivate a failed channel and raise the fault indication and chassis alarm. A channel fault does not automatically mean that the whole module has stopped operating.
Current-Loop Integration
Field current-loop outputs
Use the module for analog commands to field equipment accepting a 4-20 mA signal. The field circuit must be wired for the commoned-return, DC-coupled output arrangement.
Online maintenance
A configured hot-spare arrangement supports online replacement of a faulty module. The external termination panel and its cable provide the connection to the Tricon backplane.
Power and open-loop visibility
PWR1 and PWR2 indicate the presence of the redundant external loop-power sources. LOAD indicates that current cannot be driven to one or more outputs, helping maintenance personnel distinguish field-loop trouble from a channel diagnostic fault.

Our Company History
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.
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.
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.
