IRIG-B Distribution Adapter
The IRIG-B Distribution Adapter (GE Part No. 520-0212) is an optional IRIG-B output card
to supply an IRIG-B (TTL) signal passed from the IRIG-B Input card to attached IEDs. The
IRIG-B Distribution card provides four channels on a single terminal block. Each channel
is capable of supplying a signal to up to four IEDs, for a total of 16 IEDs. The IRIG-B
Distribution card plugs into a dedicated IRIG-B slot (slot 10) on the D400.
