Signal Repeater - MOFR

The MOFR is a compact DIN rail mountable signal repeater that performs a number of tasks, including converting time sync signals from fiber optics to copper (and vice versa), boosting signal strengths and converting one type of signal to another.

As the MOFR is completely electronically isolated, it will also provide your IEDs (Intelligent Electronic Devices) with an additional layer of electrical protection.

Copper version additional features
In addition to the primary and secondary inputs, copper version MOFRs also provide “Term” and “Loop” connectors.
Term terminal: All copper version MOFRs contain a 150 terminating resistor for terminating the end of a line of multi-dropped or daisy chained MOFRs to prevent signal reflection. To terminate the end of a line, simply connect a wire between the two Term connectors.
Loop terminal: All copper version MOFRs provide a loop terminal which is common to the primary input. This provides a simplified way of multi-dropping MOFRs without having to install two wires into the same input, or install splitters.

The PDF guides below give a brief overview of the functional differences between each version of the MOFR.
MOFR01-2HA guide MOFR01-2HA
The primary input in the MOFR01-2HA accepts DCLS IRIG-B or digital pulses. When a DCLS IRIG-B signal or digital pulse is received on the primary input, the MOFR isolates and regenerates the signal on the primary output at a voltage dictated by an external DC power source. This model also has a secondary input which accepts AM IRIG-B. The sole purpose of the secondary input is to provide isolation and it does not regenerate or amplify the signal.

MOFR01-2HD guide MOFR01-2HD
The primary input in the MOFR01-2HD accepts DCLS IRIG-B or digital pulses. When a DCLS IRIG-B signal or digital pulse is received on the primary input, the MOFR isolates, and regenerates the signal on the primary output at a voltage dictated by an external DC power source. If a DCLS IRIG-B signal is received on the input, the MOFR will isolate, and regenerate the signal as AM IRIG-B. [Click here for the guide. (400 KB)]

When a DCLS IRIG-B signal or digital pulse is received on the primary input, the MOFR isolates, regenerates and amplifies the signal in TTL, RS232 and RS422/ 485 simultaneously on the primary outputs. This model also has a secondary input which accepts AM IRIG-B. The sole purpose of the secondary input is to provide isolation and it does not regenerate or amplify the signal.
