Entek IRD 6652 DSP Protection Monitor
5
Outputs
The primary 6652 DSP outputs are described below. For a complete listing of the backplane
outputs, see “Monitor Backplane” on page 10.
l
Isolated 4–20 mA per channel into a maximum load of 600 ohms, scaled so that 20 mA
represents the full scale value for the channel
l
Buffered output signals on the front panel BNC connectors
l
Tachometer signal on the front panel BNC connector for phase reference or triggering
l
First out event line for each alarm (Alert and Danger) for each channel; these lines
signal connected monitors of an alarm condition, applying common first out alarm
indications across the monitors. In the case of a Danger alarm, this causes all connected
monitors to store their “trip trend” and “trip spectra” data for later analysis.
l
Transducer power supply at -24 VDC, +24 VDC, -12 VDC, or +12 VDC at 100 mA;
the polarity is configured with modifications to the monitor and backplane.
l
Data transferred over MODBUS interface includes overall amplitude, relay status, 30
minute trend (1 second interval), 30 minute trend prior to trip (1 second interval), trip
spectrum, phase vs. amplitude plot. Additional data includes FFT (100, 200, 400, or 800
line) computed from digitized time waveform. With tachometer signal, bandwidth fixed
at 12.5 orders up to 18,000 RPM. Without tachometer signal, bandwidth of 100 to 19
kHz, programmable. Other data includes magnitude and phase for the first three orders
and orbit plots, as well as transient analysis data for up to 300 sets of magnitude and
phase for the first three orders.
