IO-Link line driver targets harsh environments
Maintaining stable and reliable device interconnections in a noisy, industrial factory environment is a challenging task for embedded designers. To standardize these connections, the IO-Link Consortium developed a specification for a field-level, point-to-point connection system between a peripheral interface and a field device. A typical system consists of IO-Link devices such as sensors or actuators, a three-conductor interface cable, and an IO-Link Master. Supporting these industrial automation applications, ZMD AG (ZMDI) recently announced the ZIOL2411 high-voltage line driver with two independent IO-Link channels and programmable functions such as slew rate, current settings, and diagnostics. The ZIOL2411 operates as a master over the -40 °C to +85 °C temperature range and is housed in a 4 mm x 4 mm QFN24 package with an exposed die paddle to optimize heat distribution. ZMDI also provides an IO-Link development support package including an evaluation board and a Windows-based device configuration tool.
