Intellegre LLC is a small business engaged in the development and manufacture of isolated USB hubs & EtherCAT Slave products. Industrial Grade devices are designed for the harshest environments. They are EMC tested to meet heavy industrial standards. They offer up to 4 kV Isolation between transmit and receive pairs, to protect expensive equipment from dangerous ground loops and to help ensure data integrity. Principal strengths are the design of micro-controller based custom electronic systems (including EtherCAT Master & Slave systems) that are immune to EMC, ESD and harsh environmental conditions. The design expertise spans analog, mixed signal, power supplies and communication systems.
