The REx 5xx platform consists of a case, hardware modules and a set of basic functions.
The closed and partly welded steel case makes it possible to fulfill stringent EMC re-
quirements. For case size 1/1x19" IP 30 applies for the top and bottom part. IP 54 can
be obtained for the front area with accessories for flush mounting. Mounting kits are
available for rack, flush or wall mounting.
All connections are made on the rear of the case. Screw compression type terminal
blocks are used for electrical connections. Serial communication connections are made
by optical fibre connectors type Hewlett Packard (HFBR) for plastic fibres or bayonet
type ST for glass fibres.
A set of hardware modules are always included in a terminal. Application specific mod-
ules are added to create a specific terminal type or family.
The basic functions provide a terminal with basic functionality such as self supervision,
I/O-system configurator, real time clock and other functions to support the protection
and control system of a terminal.
