Power Supply Requirements
ATTENTION
!
Refer to the MobileView Guard User Manual (Publication
2727-UM002) for important information on wiring and
implementing into machine safety systems.
Electrical Specifications
24V dc Power Supply Use a 24V dc Safety Extra Low Voltage power supply.
Supply Voltage Range: 18V dc to 32V dc
Current Consumption: 300mA at 24V dc, 400mA at 18V dc
Peak Inrush Current: 5.6a maximum
Grounding Connect Earth Ground to the Junction Box using the Ground
Screw shown on page 6.
ATTENTION
!
The device meets the safety class III in accordance with
EN 61131-2 and EN 50178. The 24V power supply for the
equipment must provide appropriate isolation between the
safety-extra-low-voltage circuits and dangerous-contact voltage
circuits (for example, by safety transformers).
The power supply circuit must be protected by a 3.5A fuse.
The nominal supply voltage of the MobileView terminal
without the connection cable is 24V dc (supply voltage range:
18 -32V dc.
When planning the power supply, consider the voltage drop
in the connection cable. Specifications of the power supply
lines in the cable are:
•
Cross section: AWG24 (0.24mm2)
•
Material: zinc-coated copper strand
•
Line resistance:
<
90 Ohm/km (
<
145 Ohm/mile)
