Chapter 3 Installation and Wiring
Low Voltage Directive
This product is tested to meet Council Directive 73/23/EEC Low Voltage, by
applying the safety requirements of EN 61131-2 Programmable Controllers,
Part 2 – Equipment Requirements and Tests.
Power Requirements The module receives +5V DC and 24V DC power from the system power
supply through the CompactBus interface.
The maximum current drawn by the module is shown in the table below.
General Considerations 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
(1)
) and to circuits not
exceeding Over Voltage Category II
(2)
(IEC 60664-1).
(3)
5V DC 24V DC
100 mA 45 mA
TIP When you configure your system, ensure that the total
current draw of all the modules does not exceed the
maximum current output of the system power supply.
(1) Pollution Degree 2 is an environment where, normally, only non-conductive pollution occurs except that
occasionally a temporary conductivity caused by condensation shall be expected.
(2) Over Voltage Category II is the load level section of the electrical distribution system. At this level transient
voltages are controlled and do not exceed the impulse voltage capability of the product’s insulation.
(3) Pollution Degree 2 and Over Voltage Category II are International Electrotechnical Commission (IEC)
designations.
