6 MicroLogix 1762-IF4 Analog Input Module
Publication 1762-IN012C-EN-P - June 2013
Overview
The 1762 input module 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)
.
Install your module using these installation instructions.
1762 Input Module
(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.
Do not remove the protective debris strip until after the module and all other
equipment in the panel near the module are mounted and wiring is complete.
Once wiring is complete, remove protective debris strip. Failure to remove strip
before operating can cause overheating.
Electrostatic discharge can damage semiconductor devices inside the module.
Do not touch the connector pins or other sensitive areas.
