Output specifications The specifications for the interlock status opto-isolator outputs are as
follows:
• Output Format: open collector, open emitter transistor
• Maximum Voltage: 26 V DC
• Minimum Guaranteed Output Current Drive: 20 mA (30 mA
typical) @ 1.0 V max
Jumper X5 Jumper setting X5 selects the source for interlock status output. The
following jumper settings select the indicated interlock source:
• X5 Jumpered = HSM Board Interlocks Only
• X5 Not Jumpered = Station and HPU Interlocks
Jumpers W8/W9 Jumper settings W8/W9 determine the output polarity of the opto-
isolators.
Cable specification • 9-contact type D female EMI connector
• Backshell–EMI metallized plastic
• Cable–shielded twisted pairs (24 AWG minimum) with drain
wire(s) connected to the metallized backshell at the chassis.
J49 Auxiliary Power
Connector J49 Aux Pwr provides +5 V DC, ±15 V DC, and 24 V DC
from the chassis internal power supply to drive external high level
conditioners, proximity switches, solenoids, and so forth.
• The outputs are fused at 0.75 A to protect the power supply from
an external short.
• The fuses can be reset by shutting off power and waiting a few
minutes (the fuses automatically reset when cooled) then
reapplying power.
