ABB HMI560 560SFR02 Rack available with or without redundant power supply

Applications

The 560SFR02 rack can be used with or without redundant power supplies. Therefore, it has 2 slots for redundant power supply units (PSUs)

It therefore has 2 slots for redundant power supply units (PSUs) and 17 slots that can be used for I/O boards, communication units (CMUs), or a combination of both. It connects to other racks via the RTU560s serial peripheral bus.

Up to seven 560SFR02 racks can be connected to one system.

By using the Bus Connection Unit 560BCU05. up to 8 Communication Units (560CMU05/560CMU02R2) can be connected to the 560SFR02.

For applications with only one communication unit, the BCU05 is also required.

The BCU05 can be installed in a swing-out cabinet or frame.

A second PSU can only be inserted and made operational in slot 19. Insertion of other modules is not allowed.

If the second PSU option is not used, slot 18 can be used.

Features

19” rack height of 3 HE for single Eurocard format boards (DIN 41494). A total of 20 slots are available for mounting boards.

Each PSU has one predefined slot (slot 21 and slot 19). These slots can only be used with PSU modules.

Slots 1 through 17 can be used for I/O boards and/or CMU modules. If redundant power supplies are not used, slot 18 can be used to install additional I/O boards.

Slot assignment:

Two slots for

x 1 or 2 power supply units (each 2 slots wide)

17 slots for

x up to 8 communication units

x up to 17 I/O boards (with redundant power supply)

x up to 18 I/O boards (if only one power supply unit is used)

The physical interface of the boards uses F-type edge connectors (DIN 41612). The edge connectors in rows 2 to 20 connect the RT

The edge connectors in rows 2 to 20 connect to the RTU560 system bus and are soldered directly to the printed circuit board.

The process signals are connected via subconnectors in rows 22 to 32. The subconnectors are clamped in the cutout of the edge connector (see Figure 1).

The signal lines are connected using crimp clips with snap-in fixing. In addition to the use of prefabricated cables, it is also possible to connect single wires during commissioning!

This interface technology minimizes the number of cable connectors and the space required for the Rack 560SFR02.

The monitoring circuitry on the Rack 560SFR02 checks the board's supply voltage (24 VDC and 5 VDC).

Supply voltage faults are indicated by status relay contacts.

A separate circuit indicates power supply status. Power supply faults are also indicated by status relay contacts.

In addition to the process signal connections, the following interfaces are available on the back of the printed circuit board:

x Serial peripheral bus interface

x Status relay contacts for monitoring internal voltages (24 V DC and 5 V DC) and PSU status.

x Interface and power supply for the 560BCU05
