SERIES 8
Sixteen process-current inputs.
Honeywell 8C-PAINA1 51454470-175 is a Series 8 analog input module for sixteen single-ended process-current signals. Its 16-bit conversion and 50 ms input scan support acquisition of 4–20 mA transmitter measurements. The conformal-coated electronics accept signals from two-wire or self-powered transmitters. This configuration provides analog measurement without a HART communication interface. Individually protected transmitter power circuits simplify field-loop power conditioning. System-to-field galvanic isolation requires an external field power supply and the appropriate installation arrangement.
01 / Acquire transmitter current
The input circuitry measures each connected process-current loop and converts the signal into a digital value for the control system.
02 / Condition the input signal
Single-pole filtering and common-mode rejection help limit interference in transmitter measurements within the specified electrical limits.
03 / Protect field-loop power
Individual current-limiting circuits protect transmitter power connections without requiring a separate fuse for each protected circuit.
Power selection matters
The input accepts current from two-wire or self-powered transmitters. It is not a differential-voltage input module.
Galvanic isolation is conditional on using an external user-supplied field power source.
Maintain the correct input architecture
Choose the single-ended current-input termination arrangement and preserve the loop wiring polarity during replacement.
Keep communication expectations clear
This non-HART module measures the analog loop signal; it does not provide HART device configuration or digital variable collection.
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.
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.
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.
Support across the equipment lifecycle.
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.
Relevant datasheets and technical literature can be provided with the goods, offering useful information for product identification, installation, operation, and maintenance.
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.
We serve customers worldwide and provide reliable assistance from inquiry to delivery and after-sales service, ensuring clear and timely communication throughout the process.
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.
