SETPOINTS MODE - ANALOG OUTPUT
Description
The setpoints page 6 header. This page allows the setpoints related to the
analog output to be entered.
This message appears for two seconds to indicate that the analog output
parameter can now be specified. The 565 Relay is capable of sending out
any one of 8 actual values as analog quantities from its Analog Out
terminal on the rear of the unit. This message is replaced by a message
showing the current selection for the analog out parameter. The NEXT
CHOICE key can then be used to select the desired analog out parameter.
These parameters are the 3 phase currents, the 3 phase voltages, the
ground current, and the feeder frequency.
If external analog select is stored, the analog output parameter will be
chosen by an external device such as a programmable controller via the
565 rear. The device can request any output by presenting the correct
code at the 4 analog select terminals (A,B,C,D) on the unit. The outputs
are shown in the figure below with ON for logic 1 and OFF for logic 0. "ON"
indicates a closure or jumper between the specified terminal and the
switch return. For example an input of 1 is at terminals A, and 0 at B and
C and D, the analog out parameter will be Phase B current.

The range of the analog output may be selected using this message. Use
the NEXT CHOICE key to select either 4-20 mA or 0-1 mA depending on
the input range of the device to which the analog output is being sent.
Store the selected value. The magnitude of the analog output will then vary
linearly with the magnitude of the selected analog output parameter within
the selected range.
