Considerations
Pollution Degree 2 is an environment where, normally, only non-conductive pollution occurs except that
1
occasionally a temporary conductivity caused by condensation shall be expected.
Over Voltage Category II is the load level section of the electrical distribution system. At this level,
2
transient voltages are controlled and do not exceed the impulse voltage capability of the product's
insulation.
. Pollution Degree 2 and Over Voltage Category II are International Electrotechnical Commission (IEC)
3
designations.

2.3.2 Low Voltage Directive

This product is designed to, and verified in compliance with, European Union
Safety Standards:
• EN 61010-1
• EN 61010-2-201
The module receives power through the bus interface from the +5 VDC/+24
VDC system power supply. The maximum current drawn by the module is
shown in the table below:
5 VDC
190 mA 35 mA
The system power supply may be a 1769-PA2, -PB2, -PA4, -PB4, or the internal
supply of the MicroLogix 1500 packaged controller. The module cannot be
located more than 8 modules away from the system power supply.
Compact I/O is suitable for use in an industrial environment when installed in
accordance with these instructions. Specifically, this equipment is intended for
use in clean, dry environments (Pollution degree 2
