PR electronics 9116A-EMP Universal converter. Input for RTD, TC, Ohm, potentiometer, mA and V. Supply for 2-wire transmitters. Active / passive mA output and relay output. EMPHASIS assessed instrument for nuclear industry. SIL 2-certified via Full Assessment. Configuration and monitoring by way of detachable display front (PR 4500); process calibration, signal and relay simulation. Advanced relay configuration, e.g. setpoint, window, delay, sensor error indication and power monitoring. Copying of the configuration from one device to others of the same type via the display front. TC inputs with internal CJC or external CJC for higher accuracy. Active / passive mA output via the same two terminals.
