Accurate and reliable communication to PLC's, SCADA, and control systems
Our interface modules support all communication protocols on the market, including EtherNet IP, PROFINET, and EtherCat, and all our interface modules have direct fieldbus interfaces and analogue I/O.
Digital technology ensures high accuracy and resolution
When you combine Eilersen interface modules with Eilersen digital load cells, your measuring chain is purely digital. There is no loss of signal as there is no A/D conversion. As a result, you get the most accurate measurement and the highest resolution possible.
Standard or customized firmware
Our wide range of direct fieldbus interfaces make our interface modules easy to connect to your existing PLC’s and control systems. Besides standard firmware, all products can be delivered with customized firmware to suit your needs.
Monitor up to 16 load cells from one interface module
The integrated monitoring provides data of loads on the individual digital load cells and even offer integrated diagnostics. Even though Eilersen load cells don’t require regular maintenance, this feature makes troubleshooting fast and easy should the need for maintenance occur.
Suitable for all environments
No matter your industry or environment, we have interface modules and solutions to suit your needs. Eilersen interface modules can be delivered in ATEX and IECEx certified versions that ensure safety and reliability in demanding conditions.
