PTC and ensure interoperability between components. CalAmp’s line of ITC 220 Radio Transceivers for locomotive, base station, and wayside applications are manufactured specifically for use by North American Railroads for PTC applications. Operating between 217.6 and 222 MHz, these multi-channel software-defined radio transceivers meet railroad requirements for ITC and are designed to meet relevant railroad specifications for operation in the harshest environments.
CalAmp ITC 220 Base Station Transceivers are available in two configurations, one of which requires +24 VDC nominal input power, and the other requires +48 VDC nominal input power. Both models are almost identical, with the exception of their nominal input power requirements.
