Telex 4025A Splitter

The 4025A is a 1x4, 25-pair passive splitter built on a 50-pin connector. It takes a single 25-pair run and branches it to four destinations, which is how an installer connects multiple 800 Series master stations or ties several 4000 Series IFB control panels back to a common electronics point. It is the distribution block that keeps the wiring of a larger comms system tidy at the patch point.

Being fully passive, there is nothing to power and nothing to adjust; every pair passes straight through the 50-pin connectors. It is a rack-shelf building block for expanding an 800 Series or 4000 Series IFB installation. Telex part number F.01U.391.515.
