I/O Power (J5 pins 1, 2)
For isolated operations, the
Frequency Inputs (J5 pins 3, 4, 5),
the Digital Inputs (J5 pins 6-14 ) and
the Digital Outputs (J5 pins 15-18)
require an external source of
+5VDC power.
CAUTION: The ML-Trim is
shipped from the factory non-
isolated with J4 and J5 jumpers.
You must remove the J4 and J5
jumpers before you connect the
External Power supply or you can
damage the equipment. Do not
exceed +5VDC on the I/O Power
Input.
Use the Auxiliary Power Output
(J4 pins 1, 2) to supply power to
non-isolated operations. The
ML-Trim is shipped from the factory
with the wiring defaulted to the non-
isolated operation.
