Min/Max
Logs:
Min, Max and associated timestamp for
53 parameters stored in non-volatile memory. User can clear min/max log. All
min/max values are viewable via front panel (DM).
Trend Logs:
Configurable trend logs that store
the exact information required for the application (up to 45,867 data points).
Each trend log record can contain 1-16 parameters.
Status
Inputs:
-
Two status inputs.
-
Individual counter for each
input.
-
Input transitions are recorded in
event log.
-
Can be used to sync with external
utility meter for demand calculations and can be used to do the following
via setpoints: Operate relay(s), set an output flag, perform a snapshot, or
clear the kWhr/kVARhr power counters.

Demand
Sync Input:
Status Input can be configured to
accept external demand sync. signal.
Relay
Output:
Two form-C relays, one high speed
SPDT relay and one KYZ solid state relay.
Pulse
Output:
Either relay can be configured to
output a pulse every x kWhnet or KVARnet.
Clock:
Accurate real-time clock chip.
Accuracy + - min/month 25ºC
Security:
Password required changing setpoints,
configuration data or issuing comands.
Device
Power:
120V/240V AC 50/60Hz or 125/250V DC
Communications:
Every Powermonitor 3000 comes with a
standard native RS-485 communication port which support the DF-1 half duplex
slave protocol. This provides a cost effective method to gather information
without having to purchase separate module. DeviceNet, Remote I/O and RS-232
options also allow information access over a variety of networks. Ethernet and
Control Net available in 2000.
Compatible
Software:
-
Compatible with RSPower32 with or
without RSView.
-
Compatible with RS Energy.
-
PLC compatibility and
connectivity.
-
Interface as a generic PLC to
HMI's (Human Machine Interface).
