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.
For specific information required by EN61131-2, see the appropriate sections
in this publication, as well as the following Allen-Bradley publications:
• Industrial Automation Wiring and Grounding Guidelines for Noise
Immunity, publication 1770-4.1
• Automation Systems Catalog, publication B113
Power Requirements
The module receives power through the bus interface from the +5V dc/+24V
dc system power supply. The maximum current draw for the
1769-BOOLEAN module is:
• 5V dc: 220 mA.
• 24V dc: 0 mA.
General Considerations
The Compact I/O system 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)
(1)
Pollution Degree 2 is an environment where, normally, only nonconductive 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.
