All electrical connectionsto the Regulator Module are made with tinĆplated pin connectors. The input/output
arrangement of these pins is intended to physically isolate the different circuits, thereby minimizing electrical noise
coupling.
All optional external voltage signals which may contain electrical noise are fed through filtering and isolation circuits
prior to entering the Regulator Module. Thus reliable operation is assured even in a noiseĆpolluted industrial
environment.
A LargeĆScale Integrated Circuit (LSI) isincorporated into the Regulator Module. It drastically reducesthe number of
active devices, thereby producing excellent response characteristics and an exceptionally high reliability factor.
Physically the Module hasidentificationsand locationsprinted in highĆvisibility white paint. These calloutshelp users
identify pots, resistors, and areas where optional Kits are installed.
The Module and all optional Kitshave special covering to protect the printed circuitsfrom conductive elementssuch
as moisture and dust.
