The IED hardware consists of a case, modules, and a human machine interface (HMI). For
instance, Figure 5-1 shows the structure of the GR-series IED which can be mounted in 19"
rack. The user can find that the IED consists of a transformer module (VCT), a signal
processing and communication module (CPU), binary input and output modules (BI, BI, and
BIO, and a power supply module (PWS), which are mounted in an order from left to right. The
IED case, which is designed for rack mount as shown in Figure 5-1, has two flanges attached
on the sides. Figure 5-2 shows hardware block diagram. The module structure depends on the
GR-series models, case sizes, and the ordering specification. Therefore, the user has to check
and confirm the modules with the ordering number in advance.
(The description of IED case helps to understand the IED structure and its functions.
Based on slot reference, terminal block, slot reference, GR-Series selects different cases. VCT,
CPU, BI, BO and BIO modules, PWS and HMI are described sequentially in this chapter. The
user has to understand information provided in this chapter when wiring between the IED and
external devices and setting of the IED are performed. Hence, the user is required to read this
chapter thoroughly.)
