Chapter One--Overview
This bulletin explains how to install and operate the
LynTec NPAC rack-mount relay unit. The unit has four 20A
IEC inputs that can control either 4 or 8 single-pole relays
(80A max). In the case of the NPAC 240, the unit contains
either 4 or 8 double-pole relays (80A max). Control
signals originate externally from commands received via
the communications network or from dry contact inputs.
Acceptable communications protocols include HTTP,
