Figure 30 Control Relay Connections
Relay and KYZ Outputs
Figure 30 shows the Form C relay output connections and an example
of customer wiring to a supply voltage and two loads. Terminal R11 is
the common connection, R14 is the normally-open connection and
R12 is the normally-closed connection. You must supply the wetting
voltage and overcurrent protection for the circuit connected to the
relay output. Refer to Technical Specifications on page 59 for further
information.
The KYZ output is a solid-state relay designed for low-current
switching and long life. Its normal application is to provide a pulse
based on energy usage (or one of five other parameters) to an
external pulse accumulator. Terminal K is common, Y is
normally-open, and Z is normally-closed.
Refer to Powermonitor 3000 User Manual, publication 1404-UM001,
for further information on the application and operation of relay and
KYZ outputs.
