Overview - NR Electric PCS-9611 Instruction Manual

6.1 Overview

The modular design of this relay allows the relay to be easily upgraded or repaired by a qualified
service person. The faceplate is hinged to allow easy access to the configurable modules, and
back-plugging structure design makes it easy to repair or replace any module.
There are several types of hardware modules in this relay; each module takes a different part in
this relay. The relevant modules can be selected according to the practical engineering demands.
These modules which are supported in this relay and their module codes are listed as below.
