DLM 600W Series Isolated Remote Analog Interface Operation
M51A Option 2-7
CURRENT RESISTANCE PROGRAMMING OUTPUT: Pin-22 provides a 1mA current source
which would be connected to Pin-10, CURRENT PROGRAMMING INPUT, with a 0-5kΩ
external resistor connected between Pin-22 to Pin-12, to program the output current from
0-100% of full scale output. The INTFC SETUP switch Position-2, I, must be set to OFF (down)
to select 0-5VDC input range. Circuit is SELV, and has electrical isolation from the output of the
unit.
Auxiliary Sources
AUXILIARY 5VDC OUTPUT: Pin-15, 5VDC source output for use with logic and programming
circuits. Source capability is adequate to provide for full scale programming of output voltage,
current, or OVP when the user connects it to the appropriate programming input(s). Source is
referenced to Pin-6. Maximum output current is 15mA. Circuit is SELV, and has electrical
isolation from the output of the unit.
AUXILIARY 5VDC RETURN: Pin-6, return of 5VDC AUXILIARY source output. Circuit is
SELV, and has electrical isolation from the output of the unit.
1.25VDC REFERENCE FOR 4-20mA VOLTAGE PROGRAMMING: Pin-20, provides a
1.25VDC reference utilized by internal circuits associated with 4-20mA programming of output
voltage.
1.25VDC REFERENCE FOR 4-20mA CURRENT PROGRAMMING: Pin-11, provides a
1.25VDC reference utilized by internal circuits associated with 4-20mA programming of output
current.
