IRIG-B distribution adapter
The IRIG-B Distribution Adapter (GE Item No. 520-0212LF) is an optional IRIG-B output card
to supply a pulse width coded 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.
Terminal blocks accept a range of 24 to 14 AWG [0.2 to 2.1 mm²] Recommended wire strip
length is 0.2" [5.0 mm]. Screws shall be torqued with tool setting of 4.2 in-lb [0.46 Nm]. A 3.0
to 3.5 mm flat screwdriver tip is recommended.
