1 Product Description
1.1 Overview
The Centurion II series Remote Terminal Unit (RTU) has been designed as a
modular unit to make specification and installation of the RTUs as convenient as
possible. The base RTU can support discrete inputs and control relay outputs.
Centurion II can report to the host using standard RS-232, using an internal
modem, or using a standard Ethernet connection. The Main Module can be
specified at time of ordering to include 8 RS-422/-485 serial input ports to collect
data from various types of equipment using various protocols.
Centurion II has been designed using a PC compatible 66 MHz 486 CPU engine
and uses the PC industry standard ISA bus structure in the Main Module.
Modems and Ethernet ports are standard PC based product lines thus simplifying
expansion and maintenance.
1.2 Options
The Centurion II uses a double high 19-inch rack mount enclosure. The left side
of the enclosure houses the Main Module. The Main Module includes the CPU
board, any Ethernet or modem cards, the 8 optional RS-422/-485 serial input
ports, and other optional boards as might become available in the future.
The right side of the enclosure has 2 single height bays each capable of receiving
an I/O board. Current I/O board configurations are listed below.
The backplane has a 34-pin ribbon expansion connector labeled CHASSIS
EXPANSION. By interconnecting up to 3 expansion chassis to the base RTU you
can expand the functionality of the RTU to 512 discrete inputs and 64 discrete
outputs.
RTUs are specified by a part number containing a series of variables. The part
number is specified as Centurion II –A-B-C-D. For a complete listing see the
