JNF-050 Zone Box


The JNF-050 board is used to set the half wave signals on 4 rails within a zone. The zone box is mounted on the back of a rail and usually uses one leg of the 3 phase power to supply half wave signals to that zone. This saves substantial labor in field wiring because it is not necessary to wire every rail to the main control panel. There are 8 switches on the circuit board, one each for positive and negative of rails A,B,C, & D.


 There is one input for 120 volts AC. This input is fused for 1 Amp.


There are 4 output terminals, one for each of the 4 rails. They are labeled A, B, C, & D.


This board is available either with or without a NEMA 12 enclosure. It is installed in a Hoffman A606CH box. No sub-cplate is required.
