MAINFRAMES FOR 15-AMP MODULES*
The configurations illustrated below provide a wide selection of zone capacities
to suit almost any control application. The 5, 8 and 12 zone frames use individual
frame sections. The 16 thru 48 zone frames use 2, 3 or 4 frame sections rigidly fas-
tened together into one pre w i red integral unit which re q u i r es only one main AC
power input connection. The Current/ Voltage Monitor option will be factory
installed and must be ord e red at same time as mainframe.
MAINFRAMES FOR 30-AMP MODULES*
The 5 configurations illustrated below provide 1, 2, 3, 5 or 6 zones of 30 amp control for higher wattage
heater applications. The Curre n t / Voltage Monitor option will be factory installed and must be ord e red at
same time as mainframes.
*NOTE: Blank panel(s) should be ord e red to provide for heat dissipation and to cover unused zones in frames. Combination frames to accommodate both 15 and
30 amp modules are available on special ord e r.
