Substation Remote Terminal Unit
Powercat is an Industrial modular RTU designed specifically for Electrical Power Distribution substation applications with Opto Isolated Digital Inputs and Relay Outputs providing high levels of isolation.
Powercat RTU flexibly fits into existing SCADA systems with ease, collecting and concentrating data from Energy meters, Protection Relays, Transformer Relays, PLCs & PSUs, including Discrete connected I/O returning it to the SCADA Master or for internal logic control.
GPS Timesync module
Outputs unmodulated IRIG-B and 1PPS for direct connection to the Powercat RTU or distribution around a substation to metering and protection relays.
Powercat Communications Controller
The hub of the system, the Comms Controller combines the functions of communications controller and serial module into a single 1U module. Four slots in the rear allow serial cards or a HDLC modem to be fitted.
Includes Ethernet port, IRIG-B input, 1pps input, Tamper & Inhibit Inputs, Watchdog Alarm Relay Output, Configuration port for HMI display or Local Master RTU configuration. Intermodule Bus to communicate with I/O modules.
Serial Port card
RS232 & RS-485 outputs for Data radios, Protection Relays, Meters and other onsite IED's.
HDLC Modem card
Interface for external Analog radio.
Powercat Digital Input Module
40 paired Isolated Inputs for status monitoring. Debounce & Inversion are software selectable. LED display of each input status.
Powercat Digital Out Module
40 Paired Relay Outputs to connect with external equipment for Control. ie Contactors, Actuators, Relays & Circuit Breakers (Dibit)
Powercat Analog Input Module
16 individual 12bit Analog Inputs independently filtered for rejection of noise and ripple.
Powercat Injection Control Module
A specialised module for the control of Ripple Injection plants for Load Management purposes. All standard codes are available including Decabit, Semagyr 50, K22 & Ricontic. Local Load levelling can be achieved using PLC like logic programming providing the metering data come back to the Powercat RTU
Powercat Channel Display Module
Displays the status of each channel and allows operators to select, shed or restore a channel locally using push buttons on the front panel
Multi-port multi-protocol support including;
