Power Supply
The standard systems ship with an AC power supply; a 24 VDC power supply is op-
tional. This section provides specifications for both AC and DC power supplies.
AC Power Supply
The AC power supply provides 90-250 VAC, 50-60 Hz (autosensing), 1 A maximum at
90 VAC with 35 watts of output throughout the system’s temperature range.
DC Power Supply
The DC power supply a24 VDC input voltage for applications requiring DC in-
put power. The factory-installed power supply module pr5 V, +12 V, and -12 V
outputs.
Electrical specifications for the power supply are 18 to 36 VDC, 2.5 A maximum at 18
volts.
Expansion Power
Table 3-2 lists the available power from both the AC and DC power supplies.

Hazardous Location Installations
Xycom Automation designed the systems to meet Class I, Division 2 Hazardous Location
application requirements. Division 2 locations are locations that are normally non-
hazardous, but could potentially become hazardous should accidents expose the area to
flammable vapors, gases, or combustible dusts.
These systems have been designed as non-incendiary devices. They are not intrinsically
safe and should never be operated within a Division 1 (normally hazardous) location
when installed as described here. Nor should any peripheral interface device attached to
these systems be located within Division 1 locations unless approved and/or certified di-
ode barriers are placed in series with each individual signal and DC power line. Any
such installations are beyond the bounds of Xycom Automation design intent. Xycom
Automation accepts no responsibility for installations of this equipment or any devices
attached to this equipment in Division 1 locations.
