IMS-MRI: IRIG, 1PPS, 10MHz Input Card


This product is only compatible with Meinberg's line of modular IMS LANTIME systems.
Visit the IMS Information Page to learn more.

If an application requires the use of external synchronization sources instead of long-wave radio or GNSS signals, an MRI card enables the installed clock module to synchronize to 1PPS, 10 MHz, DCLS and AM time codes (IRIG B, AFNOR, IEEE1344 or C37.118).

Each MRI card is dedicated to one clock module, if a redundant solution requires external synchronization inputs for both clock modules, two MRI cards have to be installed. The MRI card is available with 4x BNC connectors.

Optionally, the MRI input card is also available with fiber optical inputs.
