The Power Supply<br />
This module is Version 3 and introduces a new style connector header.<br />
Version 3 modules may be used in the old Version 2 rack together with the enclosed<br />
new connector header.<br />
Note: Version 1 racks require an original Version 1 Power Supply Unit.<br />
Description<br />
Each rack requires a Power Supply Unit; this provides the supply for the Local<br />
Controller Module, or in the case of the extension rack, the Rack Interface Module<br />
plus up to <strong>12</strong> I/O modules. The Power Supply is a universal design permitting<br />
operation over a wide range of international supply voltages.<br />
The Power Supply Unit (PSU) occupies the extreme left hand position in a rack and<br />
includes indication of the status of the 24V and 5V supply rails. Absence of illumination<br />
of either indicator implies a failure of the corresponding supply rail.<br />
The PSU is configured for operation on two supply ranges. Linking 10 and 11<br />
enables the power supply to operate on lower line voltages.<br />
The PSU has a metal cover to provide shielding of electromagnetic interference to<br />
the adjacent system modules.<br />
The PSU includes a 'health' relay suitable for use in an external failsafe strategy.<br />
Cleaning<br />
Isopropyl alcohol may be used to clean the labels, do not use water or water based<br />
products or they will become illegible.<br />
A mild soap solution may be used to clean the exterior surfaces of this product.<br />
