DLM 600W Series | Isolated Remote Analog Interface Operation |
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 SourcesAUXILIARY 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.
