6.1 Making the electrical connection
6.1.1 IED connectors
6.1.1.1 Overview
The quantity and designation of connectors depend upon the type and size of the IED.
The rear cover plates are prepared with space for the maximum of HW options for
each case size and the cut-outs that are not in use are covered with a plate from factory.
Overview
Table 2: Basic modules
Module Description
Power supply module (PSM) Including a regulated DC/DC converter that
supplies auxiliary voltage to all static circuits.
• An internal fail alarm output is available.
Numerical module (NUM) Module for overall application control. All
information is processed or passed through this
module, such as configuration, settings and
communication.
Local Human machine interface (LHMI) The module consists of LED:s, an LCD, a push
button keyboard and an ethernet connector used to
connect a PC to the IED.
Transformer input module (TRM) Transformer module that galvanically separates
the internal circuits from the VT and CT circuits. It
has 12 analog inputs.
Analog digital conversion module (ADM) Slot mounted PCB with A/D conversion.
