MRI-4S/USB/IS/R

USB to 4 port (RS232) Serial hub with Isolation and Surge Protection

This USB Serial Adapter not only expands your PC COM port capabilities, it greatly improves protection to your devices from electrical interference.

The MRI-4S/USB/IS is a 4 Port USB-to-serial hubs with 2 KV optical isolation protection on each serial port. It includes standard serial port features, such as baud rates up to 921.6 Kbps, built-in 15 KV ESD protection, and has Hi-Speed USB 2.0 operation up to 480 Mbps.

Stock : 1

Each serial port includes 2 KV DC optical isolation protection, which is required for many commercial and industrial applications. With optical isolation, the hub and PC are protected from electrical spikes and surges on the data line. For industrial applications, these electrical spikes could shut down an assembly line or an entire plant if not addressed. In worst-case scenarios, facilities may suffer extensive damage. By including optical isolation on each port, the MRi IS range not only provides PCs with COM port expansion, but also with protection from potentially damaging electrical spikes.
