The Callistonx is cost-effective RTU with a range of features and options. Callistonx is compliant to IEC 61850 with 0.1% measurement accuracy for AC measurements, disturbance and event recording and has a wealth of protection functions.
Two independent processors ensure consistent high performance with a powerful DSP dedicated to time-critical AC and protection functionality, with a separate ARM9 processor managing higher level applications and communications. SOE time-stamping to 1ms is standard and the optional integrated GPS, which provides both time and position, ensures consistency across geographically remote installations. Communications can be either via the built-in Ethernet port or over traditional serial channels wit ha host of international standard protocols available for both mechanisms: IEC 61850, DNP3, IEC 60870-5 and Modbus.
Callistonx is a high performing remote terminal unit, with easy-to-use configuration tools, an industry standard IEC 61131-3 logic application and secure web browser technology. These software tools, along with a high contrast LCD, ensure efficient deployment and ongoing ease of maintenance through common product knowledge to support installations from EHV through to LV networks.
The Callistonx Utility Controller provides six expansion slots for instrumentation AC and DC analogues, digital I/O and comprehensive IED support using plug-in modules.
Callistonx expansion modules plug into the Utility Controller and provide a range potential customisations for the RTU. The modules include:
Integral Communications Ports
I/O Expansion Modules
Communications Expansion Modules
Power Supply Unit
Listed below are some of the Frequently Asked Questions we receive for Callistonx. Please contact us if you need more information.
Q: What EMC and Type Testing standards does the product conform to?
A: Please provide us with your details and we will send them to you.
Q: Can you provide me with information giving details of the Callistonx cassettes/modules power consumption?
A: Yes – please provide us with your details and we will send them to you.
Q: What is the burden of the AC Cassettes when measuring a CT or a VT?
A: CT – the burden of our current cassette varies depending on which range is being used. At full load the burden is 140uW for the 1 amp range and 875uW for the 5 amp range. VT – each leg of the voltage measuring cassette offers an impedance of approximately 950K ohm to system 0V (usually neutral).
Q: None of the relays in the output cassettes are functioning correctly?
A: Ensure that the shorting link is connected between TB1 1 & 2.
The Callistonx is a highly functional product and provides a number of functions:
