IMS-MRI

SKU: IMS-MRI

IRIG, 1PPS, 10MHz Input Card

If an application requires to use external Synchronisation sources instead of radio/GNSS signals, an MRI card enables the installed clock module to Synchronise to 1PPS, 10MHz, 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 Synchronisation 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.

Key Features

  • 10MHz, PPS, IRIG, TC-AM / TC-DCLS reference signals
  • Option: 4 x 850nm Multimode inputs via ST connector
