110VAC, or 220VAC X1 and X2 on the SR06AM
■ Selectable Inputs—Dual or ■ Selectable reset modes—
single N/C input channels are Manual or automatic reset
switch selectable mode is switch selectable on
the SR06AM
■ Outputs—the SR06AM has
3 N/O outputs to route power to
the coils of power contactors
plus 1 N/C auxiliary output for
signaling purposes
