Part of the 70 Series Measurement System, the M571 is a Compact Single Line, Single or Dual Bus monitoring and recording IED. It uses common firmware and software to provide fast, precise, electrical measurements, fault and event records, and trend logs.
The M571 provides flexible and easy interfacing with multiple protocols, including IEC61850, and physical links for constant, cost-effective monitoring and recording. This IED can be fitted with inputs for connection to either protection or measurement CTs and ensures precise, speedy results.
Basic measurement device and more
The M571 provides an economical solution for basic measurement of SCADA data. It also provides advanced recording and communications functions not found in basic measurement devices.
Operators have the option to monitor status inputs and control relay outputs. This IED can simultaneously provide information and control to multiple clients or masters and offers both copper and fibre Ethernet ports. Options are built-in and must be specified at time of order.
The M571 supports the 70D Display Family of separately mounted displays.
Cost-effective precision recording and monitoring of system stability
M571 enables a low-cost entry into monitoring and recording substation automation applications including fault recording. It provides monitoring of system stability with six simultaneous recorders and extensive non-volatile memory.
GOOSE cross triggers permit synchronising records between multiple 70 Series IEDs. Network time synchronisation and application software manage the record collection process.
