点I/O™ 适配器，例如1734-ADN DeviceNet适配器。
•符合CE低压指令（LVD）、现场电源和所有
连接的I/O必须由符合以下要求的电源供电：
安全超低压（SELV）或保护超低压（PELV）。
•为了遵守UL限制，现场电源和所有连接设备必须：
由符合以下要求的单一电源供电：2级。
警告：当背板电源打开时插入或卸下模块时，
可能发生电弧。这可能会在危险位置引起爆炸
装置。之前，确保电源已断开或该区域无危险
诉讼程序反复电弧会导致两个触点过度磨损
模块及其配套连接器。磨损的触点可能会产生电气
可能影响模块操作的电阻。

 Do not remove or replace an Adapter Module while power is applied.
Interruption of the backplane can result in unintentional operation or
machine motion.
• Do not discard the end cap. Use this end cap to cover the exposed
interconnections on the last mounting base on the DIN rail. Failure to do so
could result in equipment damage or injury from electric shock.
• If this equipment is used in a manner not specified by the manufacturer, the
protection provided by the equipment may be impaired.
• Do not connect 120/240V AC power to this supply.
• Use the 1734-EP24DC and 1734-EP24DCK expansion power supply only with
POINT I/O™ adapters, such as the 1734-ADN DeviceNet adapter.
• To comply with the CE Low Voltage Directive (LVD), field power and all
connected I/O must be powered from a source compliant with the following:
Safety Extra Low Voltage (SELV) or Protected Extra Low Voltage (PELV).
• To comply with UL restrictions, field power and all connected devices must be
powered from a single source compliant with the following: Class 2.
WARNING: When you insert or remove the module while backplane power is on,
an electrical arc can occur. This could cause an explosion in hazardous location
installations. Be sure that power is removed or the area is nonhazardous before
proceeding. Repeated electrical arcing causes excessive wear to contacts on both
the module and its mating connector. Worn contacts may create electrical
resistance that can affect module operation.

POINT I/O 24V DC Expansion Power Supply
Electrical Safety Considerations
WARNING: If you connect or disconnect the communication cable with power
applied to this module or any device on the network, an electrical arc can occur.
This could cause an explosion in hazardous location installations.
ATTENTION:
• This equipment is certified for use only within the surrounding air temperature
range of -20…+55 °C (-4…+131 °F). The equipment must not be used
outside of this range.
• Use only a soft dry anti-static cloth to wipe down equipment. Do not use any
cleaning agents.
At the end of its life, this equipment should be collected separately from any
unsorted municipal waste.

POINT I/O 24V DC Expansion Power Supply
About the Power Supply
The expansion power supply passes 24V DC field power to the I/O modules to
the right of it. The expansion power supply extends the backplane bus power for
up to 17 I/O modules to the right of the supply and creates a new field voltage
partition segment for driving field devices. The expansion power supply
separates field power from I/O modules to the left of the unit, effectively
providing functional and logical partitioning for the following.
• Separate field power between input and output modules.
• Separate field power to the analog and digital modules.
• Group modules to perform a specific task or function.
The dark-gray color of the expansion power supply allows for easy visual
inspection and identification. Refer to the figure to identify external power
supply components.
Use multiple expansion power supplies with POINT I/O™ adapters to assemble
a full system. With any POINT I/O™ adapter, use an expansion power supply to
add additional modules in 4...17 module increments
