Courtesy: TurckTurck's 4AI4AO-VI analog I/O module is compatible with two of the company’s BL distributed I/O products: BL67 and BL Compact system. The module features four analog inputs for current or voltage and four analog outputs for voltage.

The 4AI4AO-VI is designed for use with Turck’s BL67 modular I/O system and BL Compact system. BL67 combines all of the flexibility of an in-the-cabinet I/O system with modularity, ruggedness and connectorization, while the BL Compact system is a revolutionary on-the-machine solution that obtains and transmits signals via diverse fieldbus protocols, without requiring a protective enclosure. Supporting both M8 and M12 I/O connectors and offering compatibility with a variety of communication protocols, such as Ethernet/IP, DeviceNet, CANopen and Modbus TCP, the BL family provides a high degree of I/O versatility for a wide range of applications.

The 4AI4AO-VI is constructed to withstand diverse environmental challenges. Operating in temperatures ranging from -40 to 70 degrees Celsius, rated to IP67 and UL listed, the module provides optimal performance in applications that yield extreme temperatures, moisture, shock or vibration—accommodating even the most demanding application requirements.
