Digital Output 2 (J6 pin 16,17)
The Digital Output 2 can be programmed to activate as a function of various alarm
conditions or as a function of the drive enable logic. Refer to CP-11 for functional
allocation of Digital Output 2.
NOTE: This is an open-collector relay driver. Use an external DC power supply to
power the relays. Free-wheeling diodes are incorporated internally in the
MLP–Trim and do not need to be added externally.

Auxiliary DC Power (J1 pin 1, 2)
The 5 volt output (J1 pin 1) is a DC regulated output that can be used to power
encoders or other auxiliary equipment that is used in conjunction with the MLP–Trim. If
this output is used, it will nullify optical isolation.
