Keterex USB-150 Full Speed Isolator

The Keterex USB-150 Full Speed USB Isolator provides up to 1500Vrms of galvanic isolation between a USB host and USB peripheral. The Keterex USB-150 is designed for applications in which a USB host and peripheral device operate at different ground potentials or in which supply noise from the USB host needs to be eliminated. Any full-speed USB device can be isolated using the USB-150 and standard USB cables. This Keterex full speed isolator supports USB 2.0 full-speed data rates and requires no external power supply. In addition, the USB-150 provides an isolated 5V supply to the downstream device at up to 400mA.

Keterex USB-910H Embedded Systems Interface

The Keterex USB-910H Embedded Systems Interface lets you turn a PC into an SPI, I²C, SMBus, or parallel GPIO controller. The Keterex USB-910H provides connectivity between a host PC and an embedded system requiring an I²C, SMBus, or SPI protocol. This embedded systems interface can support other protocols by bit-banging up to 9 available general-purpose I/O (GPIO). USB transactions are generated on the host PC using either the Keterex USB-900 Control Center application or calls to a provided API. The Keterex USB-910H adapter converts these transactions to I²C, SMBus, SPI, or GPIO operations. The USB-910H provides configurable I/O voltage levels from 1.65V to 5V. The voltage can be connected to the target hardware, providing up to 400mA to the target device.
