Matrix Pgm Expanders; Transistor Output Expander Mx-Rox8T; Relay Output Expander Mx-Rox8R - Pyronix Matrix 424 Installation Manual

2.10 Matrix PGM Expanders

The ROX8R/8T is an additional feature to the Matrix panel, which will enable all 12 programmable outputs on
the matrix panel to be used. See cabling restrictions in Section 1.9 for the KEN values, which may be used
with the output expander.

2.10.2 Relay Output Expander MX-ROX8R

NOTE: The relay output expander provides voltage free change over contacts. This is more flexible
and can isolate the circuit from the system.
