Modular
SCADA Remote Terminal Unit
-----------------------------------------------------
Powercat is
an industrial modular RTU
designed specifically for
Electrical Distribution
and Telemetry applications.
Powercat flexibly fits into
existing SCADA systems with
ease, collecting and concentrating
data from
Energy meters, Protection
relays, Transformer relays,
PLCs, PSUs and discrete
I/O to return it to the
SCADA Master or for internal
program control.
----------------------------------------------------- |
|
|
- High
I/O isolation
- Multiple
protocol support
DNP3 Master and Slave,
Modbus, DFI, Conitel and
others
- PLC functionality
- GPS Time
Synchronisation for RTU
&
protection relays onsite
- Local
HMI/Config tools
- Ethernet
interface TPC/IP
- Load
Management System modules
|
 |
---------------------------------------------
What’s New
---------------------------------------------
Powercat is an update
to our Powerlink RTU product with
a new Architecture, faster M32c
processor, Flash RAM and additional
interfaces for Time Syncing and
IP communications as standard.

Communications
Controller Module
The
hub of the system, the Comms Controller
combines the functions of two of
our earlier products, the communications
controller and serial module into
a single module. Four slots in the
rear of the module allow users to
fit interfaces for
- modems for
radio or line comms for HDLC
or Conitel
- Isolated RS-232/RS-485
serial card for Asynch protocols
DNP3, Modbus, DF-1
In addition each module
is fitted with
- IRIG-B Time
Sync input
- Security Inputs
(Tamper and Inhibit), Alarm
Relay Output
- Config port
for a Local Aspex HMI/Display
or Local Master RTU setup
- Intermodule
bus port to communicate with
other I/O modules

Digital
Input Module
40 paired
isolated inputs for status
monitoring. Debounce and
Inversion are software selectable.
LED display of each input
status. |
|
 |
|
|
| |
Digital
Output Module
40 paired relay outputs
to connect with external
equipment for Control (i.e.
contactors, actuators and
relays). Protection against
operation during power up/down
and defect states. |
|
 |
|
|
| |
Analog
Input Module
Connects
analog transducers or inputs
with 12 bit accuracy. Inputs
are independently filtered
for rejection of noise and
ripple. |
|
 |
|
|
| |
Pulse
Input Module
Power
and flow meters are connected
to the Pulse Input module;
output pulses provide calculated
consumption and flow information
at the Master. These can
later be used in pre-formatted
reports or spreadsheets. |
|
 |
|
|
| |
Serial
I/O Module
Allows
the connection of serial
IEDs i.e. reclosers, feeder
relays, generator relays,
transformer VRRs, flow meters,
valve actuators, PLCs, VSDs
etc without the need to
independently wire discrete
I/O modules. Uses standard
protocols (DNP3.0, Modbus,
DF-1) and specialised protocols
(Cooper 2179, Harris 6000
and others). |
|
 |
|
|
| |
Injection
Controller Module
A specialised
module for the control of
ripple injection plant for
load management purposes.
All standard codes catered
for incl Enermet Decabit,
L&G Semagyr 50, Plessey
Rhythmatic, K22, (Pulsadis,
Riccontic, Telegyr -Enermet’s
IP). Local load levelling
can be achieved using RTU
logic programming and load
metering providing it comes
back to Powercat. |
|
 |
|
|
| |
| Injection
Display Module
A specialised
module that displays the
status of each injection
control load channel and
allows local control to
shed /restore the channel.

Powercat
Features
Wide
range of communications
options with the SCADA Master
2W, 4W, Synch Radio, Asynch
Data Radio, IP, Fibre Optic.
Modular
Any combination
of DI, DO, AI, Serial IO,
Time Sync & Load Control
modules may be connected
to custom build your substation
interface. Modules
use a flexible intermodule
bus for comms with the Communications
Controller.
High
Isolation
- Inputs
are isolated in pairs
to withstand 2kV/1min
or 5kVp BIL
- Relay
Outputs are paired and
share a common
- Serial
ports are isolated to
IEC 255-5
- Optional
RS232 and RS485 Fibre
Optic converters
Logic
Programming Functionality
Each Powercat RTU can operate
as a programmable logic controller
with programs either downloaded
from the SCADA Master over
the communications channel
or loaded via the configuration
port.
- Logic
programs for Alarm conditioning,
selective data storage,
Local Load Management
- Preprocess
data at the RTU as virtual
I/O
- Programs
can run at the SCADA Master
or RTU allowing online
program creation and testing
Ethernet
Port
- Connect
via IP standard 10/100-Base-T
