9330/9350 Advanced Power Meters
Features and Benefits
Inputs/Outputs*
The 9300 series offers a variety of
analog and digital I/O combinations.
The analog I/O option can be specified
for both meters, allowing you to
monitor a wide range of conditions,
such as flow rates, device cycles
(RPM), fuel levels, oil pressures and
transformer temperatures. You can
output energy pulses to an RTU or
perform equipment control operations.
Status Inputs
Four optically isolated digital inputs
on the 9330 and 9350 meters can
monitor status, count transducer
pulses, breaker trips and pulses from
any external "volts free" dry contact.
Digital Outputs
9300 series meters are equipped with
4 fully programmable digital output
ports, suitable for pulsing or controlling
relays. An optional extension board
provides external relays that can be
controlled by the digital outputs.
The Infrared Data Port and/or a rear
panel LED can also be used for
energy pulsing.
Example 9330 Communication Connections
* Analog I/O is not available with all form factors
and communictions configurations. Please
check attached order information for
supported combinations.
Relay Extension Board
Optional Digital Output Extension
Board extends the four digital outputs
to allow relay control. A range of
relay options are available. (Please
contact Siemens.)
Analog Inputs/Outputs
Any meter in the 9300 Series can be
equipped with an optional analog I/O
card featuring:
4 analog inputs accepting 0–1mA
or 0–20 mA, (scalable to 4–20mA)
4 analog outputs accepting 0–1mA
or 0–20 mA, (scalable to 4–20mA)
When equipped with analog I/O, TRAN
base units cannot be ordered with a
remote display, (RMD).
Connections and LEDs
The meters support 4-wire Wye, Delta,
3-wire Wye, direct Delta and Single
Phase systems. They have 3 voltage
and 3 current inputs.
No PTs required on the voltage inputs
for Wye systems up to 347/600 VAC
and Delta systems up to 600 VAC
Accept CTs with 5 Amp nominal/10
Amp full scale outputs
Captured-wire connector (CWC)
option
Inputs pass the ANSI/IEEE
C37.90.1.1989 surge withstand
and fast transient test
Example connections
4-Wire Wye (Direct Connection)
3-Wire Wye (2 PTS and 3 CTS)
Mounting
Basic models have an integrated
display and fit in a DIN standard
92 mm x 92 mm (3.6 in. x 3.6 in.)
panel cutout, secured by sliding
clamps tightened by thumbscrews.
TRAN models have no integrated
display and can be flush-mounted
against any flat surface. Optional
DIN rail mount is also available.
The RMD (Remote Display Module)
fits a DIN standard cutout up to
1.8 m (6 ft.) from the base unit.
Off-the-shelf panel punches can be
purchased. Contact us for sources.
An adapter plate is available to
facilitate the conversion from
our 4000 series meters to the
9330 / 9350 series. Contact us for
more information.
9330 / 9350 series units weigh
approx. 6.0 lbs/2.3 kg. Box
dimensions are 16x10x7 inches;
40x26x10 cm
Switchboard Draw-out Cases
9330 / 9350 series meters can be
ordered with switchboard hardware,
which is offered as a complete kit
(internal cage with external casing)
and as a "retro-fit" kit designed to
fit into existing GE S1 or ABB FT21
switchboard cases.
