RUGGEDCOM RMC8388

The RUGGEDCOM RMC8388 is a rugged, small form factor time converter that converts PTP (IEEE 1588) to IRIG-B or PPS time signals. The RUGGEDCOM RMC8388 saves high maintenance costs on legacy coax cabling by allowing their replacement with standard Ethernet cabling for both communications and timing purposes, all the way to the switchyard cabinets.

Compact time protocol converter

Configure your RUGGEDCOM product

The RUGGEDCOM-Selector lets you configure RUGGEDCOM products quickly, easily, and efficiently, by using targeted navigation through selection menus or by entering item numbers. Selected products can then be ordered directly by transferring the parts list into the Industry Mall.
