The SPR system protection relay is a microprocessor based panel mounted device offering protection, control, measurement and communication of up to 37 power parameters in a single package. The SPR monitors three phases of voltage and current and provides up to twelve user definable relay outputs. The high contrast 80 character backlit LCD display allows the user to monitor any of the measured parameters, inspect setpoint details and relay contact status. The setpoints and configuration are all fully programmable via the simple menu driven user interface.

Remote monitoring of status information is achievable via the integral RS 485 communication port which supports Modbus RTU protocol. SPR is suitable for many diverse applications, providing cost effective protection of expensive power assets.
