Ordering Information

2–4
The 469 is equipped with 3 fully functional and independent communications ports. The
front panel RS232 port may be used for 469 settings programming, local interrogation or
control, and upgrading of 469 firmware. The Computer RS485 port may be connected to a
PLC, DCS, or PC based user interface program. The Auxiliary RS485 port may be used for
redundancy or simultaneous interrogation and/or control from a second PLC, DCS, or PC
software.
There are also four 4 to 20 mA or 0 to 1 mA (as specified with order) transducer outputs
that may be assigned to any measured parameter. The range of these outputs is scalable.
Additional features are outlined below.
METERING:
• Voltage
• Current and amps demand
• Real power, kW demand, kW power consumption
• Apparent power and kVA demand
• Reactive power, kvar demand, kvar consumption/generation
• Frequency
• Power factor
• RTD
• Speed in RPM with a key phasor input
• User-programmable analog inputs.
ADDITIONAL FEATURES:
• Drawout case (for ease of maintenance/testing)
• Reduced voltage starting control for single transition
• Trip coil supervision
• Flash memory for easy firmware updates
All 469 features are standard; there are no options. The phase CT secondaries, control
power, and analog output range must be specified at the time of order. The 469 differential
CT inputs are field programmable for CTs with 1 A or 5 A secondaries. There are two
ground CT inputs, one for the GE Grid Solutions 50:0.025 core balance CT and one for a
ground CT with a 1 A or 5 A secondary, also field programmable. The VT inputs will
accommodate VTs in either a delta or wye configuration. The output relays are always
non-failsafe with the exception of the service relay. The EnerVista 469 Setup software is
provided with each unit. A metal demo case may be ordered for demonstration or testing
purposes.
