PSM Module Description and Specifications
The Power Sync and Measurement (PSM) system monitors two independent three-phase
power grids. It incorporates advanced digital signal processor (DSP) technology to
continuously process three voltage inputs and four current inputs for each grid.
Measurements include RMS voltages, RMS currents, RMS power, frequency, and phase
relationship between the phase voltages of both grids.
The PSM module performs calculations on each captured waveform, with the DSP
processing the data in less than two-thirds of a power line cycle. The PSM module can be
used with wye or delta type three-phase power systems or with single-phase power
systems.
The PSM system can be used for applications such as:
Electrical power consumption monitoring and reporting
Fault monitoring
Generator control features for generator to power grid synchronization
Demand penalty cost reduction/load shedding
The PSM system consists of:
PSM module –A standard IC694 module that mounts in an RX3i main rack. The
PSM module provides the DSP capability.
Terminal Assembly –A panel-mounted unit that provides the interface between the
PSM module and the input transformers.
Interface cables –Provide the GRID 1 and GRID 2 connections between the PSM
module and the Terminal Assembly.
PSM System Features
Uses standard, user-supplied current transformers (CTs) and potential transformers
(PTs) as its input devices.
Accurately measures RMS voltage and current, power, power factor, frequency,
energy, and total, three-phase, 15-minute power demand.
Provides two isolated relays that close when the voltage phase relationships
between the two monitored grids are within the specified ANSI 25 limits provided by
the RX3i host controller. These contacts can be used for general-purpose, lamp duty
or pilot duty loads. Voltage and current ratings for these load types are provided on
page 1-5.
Provides a cable monitoring function that indicates when the cables linking the PSM
module and Terminal Assembly are correctly installed.
Can be easily calibrated using the Proficy* Machine Edition (PME) software to enter
calibration constants for the PSM module and Terminal Assembly.
The PSM001 module supports hot swap (removal and replacement in an RX3i rack
that is under power).

PSM Module
In addition to configuring the PSM module upon project
download from PME, the RX3i CPU can control the PSM module
by updating configuration data from the RX3i in the form of %AQ
data words and %Q mode control bits during each sweep.
The PSM module provides calculated data to the CPU in the
form of %AI data words and %I status bits each sweep. The
information sent by the PSM module includes power system
measurements and discrete fault status.
Connectors
The PSM module provides two Mini-D 20-pin connectors that
accept the GRID 1 and GRID 2 voltage and current signals from
the Terminal Assembly.
Indicators
Four LEDs provide status indications for the PSM system.

Terminal Assembly
The Terminal Assembly accepts three voltage inputs and four current inputs for each of
two grids. The Terminal Assembly translates the 0–5 A current signals and the
45–690 VAC RMS voltage signals to low voltage signals for use by the PSM module.
Voltage inputs are connected through external, user-supplied potential transformers (PT).
External, appropriately-sized current transformers (CT) are used to translate grid or load
currents down to the 0–5 A range required by the Terminal Assembly.
Connectors The Terminal Assembly provides two terminal blocks, each with 12 screw terminals, for
the voltage and current inputs from the grids. The terminals accept up to 10 AWG wire
commonly used in power utility applications.
The Terminal Assembly provides two pairs of Mini-D 20-pin connectors for connection to
the PSM module using the interface cables. The 45–120 VAC or 120–690 VAC range is
selected by connecting the interface cables to the corresponding pair of Mini-D
connectors.
When the cables are connected to the correct grid and matching voltage ranges, the PSM
module provides an indication that the cables are correctly attached to the unit.
A four-pin pluggable connector provides two isolated solid state relay contacts that close
when the correct voltage, phase, and relative frequency differences match the configured
criteria for synchronization of the GRID1 and GRID2 signals.
Note: The Terminal Assembly is not equipped with CT shorting-bars. These must be
provided separately by the user.
