Switching Options
Option 1: External Power Supply
Option 2: Internal Power Supply
Option 3: PLC
Note 1: The minimum "on time" or "close time"
of each switch is 10m seconds.
Note 2: The switches in the above schematics
can be replaced with any kind of dry contact
switches; or any kind of relays. Examples:
mechanical relays, momentary contact switches,
toggle switches, transistors, mosfets, solid state
relays, PLC outputs, etc.
Note 3: The logic inputs of the clutch/brake
control are optically isolated.

Note 1: In single mode, when power is applied
to the control, Ch1 comes on at adjusted volt-
age until a logic input changes the output volt-
ages.
Note 2: In single mode the control can not “turn
off” both channels at the same time; or “turn
on” both channels at the same time.
Note 3: When voltage is applied to “Ch2 over-
ride”, Ch2 and Ch1 logic inputs are ignored and
the outputs are changed to:
Ch1 = full torque and Ch2 = off.
When power is removed from “Ch2 override”,
the control reads the logic inputs and changes
the voltage output accordingly. If no power is
applied to the logic inputs when power is
removed from Ch2 override, then the output
voltages remain at:
Ch 1 = full torque for Ch 1 and Ch2 = Off.
