Connectors and inputs

The rear connectors and rear side layout of the Intelligent Electronic Device

(IED) are illustrated in figures 3 and 4.

Viewed from right to left, in figure 3, the connectors are:

1. The connector for the analog inputs of the TRM2 (X411) and TRM1 (X401):

The TRM cards are factory equipped with a fixed number of current (6-12) and

voltage (3-6) inputs. Make sure the delivered configuration matches the order.

The use of analog inputs is defined in the configuration of the IED where each

input is tied to a selected function/s.

2. The optional communication board for communication between IEDs or to

remote line end is available on ports X312, X313, X302 and X303 as ordered.

See figure 4 for details.

3. Communication interfaces for LON, IEC 61850-8-1, SPA/IEC 870-5-103 or

DNP according to included options. One or two optical ethernet ports (X311)

exist for communication to substation control systems and substation monitor-

ing systems. Two optical ports (X301) for LON, SPA or IEC 870-5-103 com-

munication can be included. LON plus any of the other protocols can be

included. See figure 4 for details.

4. The Milliampere Input Module (MIM) is used to interface transducer signals

in the 0-20 mA range such as temperature and pressure signals from

transducers.

5. The IO board connectors for IOM, BIM or BOM as ordered. Starting with

slot 3 (Connectors X31, X32) seen from the rear left side they are equipped as

ordered. Check the ordering document. Binary inputs have auxiliary voltage

levels as ordered and are designed to be safe against capacitive discharges and

bridge initial contact resistance in external contact. See figure 4 for details.

6. The Power Supply Module (PSM) provides the boards with power. Depend-

ing on the PSM ordered, the rated input voltage range is 24-60 VDC or

90-250 VDC with a tolerance of 20%. See figure 4 for details.

Each connection terminal or port on the rear side of the IED is numbered. The

numbers are stamped into the rear panel above each opening. Viewed from the

rear, the lowest numbers are to the left and increase to the right. All numbers

begin with an X followed by two or three digits. Analog inputs can be ordered

with ring lug connectors as an alternative. The analog inputs are dimensioned

for conductor cross section areas of up to 6 mm

puts plus the DC supply are dimensioned for up to 2 x 1.5 mm

Refer to the Installation and commissioning manual for mounting instructions.

The torque used to tighten connector screws is 1.0 Nm for analog and 0.4 Nm

for binary connections.

The casing, each TRM and the PSM have their own earth connections.

Details regarding hardware modules, refer to the Technical reference manual

which includes diagrams (schematics) of the electrical connections to the

IED 670.

and the binary inputs and out-

conductors.
