Status Inputs
Up to four dry (non-powered) contacts can be connected to the
PowerMonitor 5000 unit status inputs. The status input derives 24V DC power
from its internal power supply.
Connect status inputs by using shielded, twisted-pair cable with the shield
connected to the ground bus or other low-impedance earth ground at the contact
end only. The diagram indicates typical status input wiring.

KYZ and Relay Outputs
The KYZ solid-state relay output can be connected to an external pulse
accumulator or controller. Relay outputs can be used for control of loads,
switching of circuit breakers, signaling, and other applications. The external
device or circuit must provide wetting voltage. The KYZ output is designed for
low-current switching. The diagram indicates typical KYZ and relay output
wiring.
