USB to current loop converter with selectable active and passive modes of 20mA/40mA.

- Selectable active and passive types of 20mA/40mA (can be set individually for transmission and reception). - The signal logic on the USB side can be inverted in response to the current state on the current loop side. - When using multi-drop connections, it is possible to cancel the echo of the data sent to the current loop side. - Significantly miniaturized and space-saving compared to the conventional SI series. - Achieves industry-leading 3000Vdc signal isolation voltage. - Capable of USB bus-powered operation, eliminating the need for an external power supply. - Comes with a virtual COM port driver compatible with Windows 10. - Operating temperature range of -20 to 60 °C, capable of withstanding harsh environments. - Features a robust and noise-resistant compact metal housing. - Offers various mounting options including 35mm DIN rail, wall mounting, and magnets. - Environmentally friendly low power consumption design.

basic information

The SI-10US is a high-speed current loop converter that bi-directionally converts a computer's USB port to current loop transmission. The signal between the current loop and USB is insulated with a high voltage resistance of 3000V, making it ideal for FA applications that require high safety and reliability. It features the ability to separately configure the active current loop, which supplies current to the circuit from the built-in constant current source of the SI-10US, and the passive current loop, which does not supply current to the line, for both transmitted and received signals. Additionally, it has a function to cancel the echo of the data it has transmitted during multi-drop connections, allowing most current loop communication devices to be used from a computer's USB interface. Furthermore, it has been miniaturized compared to the conventional SI series communication converters, making it space-saving. With a wide operating temperature range and a noise-resistant metal housing, it is an ideal interface converter for factory equipment and inspection systems that require high reliability.
