Model Number
The Omni 3000 is designed to accept two combo modules, one 12-channel
digital I/O module and one dual-channel serial I/O module. The Omni
6000 can accept up to six combo modules, two 12-channel digital I/O
modules and two dual channel serial I/O modules. If the number of
combo modules required, including communication
boards and spare I/O's, is greater than the Omni 3000 limits,
select an Omni 6000.
Remember to provide for sufficient spare I/O for
your computer system. A minimum I/O system is not a manufacturer-recommended
practice in important measurement applications.
Combo Modules Required
'A' modules provide four input channels, two selectable as analog
only input channels. The third and fourth input channels are selectable
analog or pulse. Two analog outputs are available.
'B' modules provide four input channels where the first three process
inputs are identical to the 'A' module and the fourth channel is fixed
to provide a periodic time density pulse input. One analog output
is provided. The number of 'B' type combo modules required are equal
to the number of digital pulse densitometers that are interfacing
(see type 'E/D' below).
'E' modules provide two selectable analog inputs and either two single
pulse inputs or one dual pulse input, when pulse fidelity checking
is required. One double chronometry detector switch input and two
analog outputs are also provided.
'E/D' modules provide four process inputs including two analogs and
two periodic time density pulse inputs on the third and fourth channels.
Two analog outputs are provided.
'H' denotes a four input digital module used solely with Honeywell
Smartline™ 3000 transmitters.
'HV' modules have four Honeywell DE™ digital protocol ports
dedicated to Honeywell
SMV 3000 transmitters. Two analog outputs are provided.
'SV' modules provide two RS-485 channels to be used with Rosemount
3095FB multivariable transmitters, Micro Motion RFT 9739, Daniel,
Instromet,
FMC Kongsberg,
Caldon and Krohne ultrasonic devices. There are six analog outputs
provided.
To determine the total number of combo modules (Types 'A' + 'B' +
'E' + 'E/D' + 'H' + 'HV' + 'SV') required, the number of temperatures,
pressures, densitometers, gravitometers, differential pressures, turbine/PD
meter pick-offs that will have interfacing connections should be added.
Remember to provide for sufficient space for physical I/O. Round the
number up to the nearest increment of four and divide that number
by four. Please consult Omni when 'HV' or 'SV' modules are required.
Digital I/O Modules Required
'1D' (12 digital I/O) is always used when specifying an Omni 3000.
An Omni 6000 can use '2D'. To determine the number of digital I/O
modules needed, the number of digital I/O points required must be
added for the total. These include, but are not limited to prover
detector inputs, sampler pulse outputs, control outputs, alarm outputs
and control inputs.
Serial / Ethernet I/O Modules Required
The Omni 3000 is limited to one dual serial I/O module. The Omni 6000
can accept up to three serial I/O modules. The first port can be configured
for a printer or Modbus™. All sixports are Modbus-compatible
slaves. Port #2 can be used as a Modbus master for redundant flow
computer applications and communicating with slave devices. The SE
Module provides two communication channels. Channel one is an
RS-232/RS-485 serial channel and channel two is a 10BaseT Ethernet
channel. The computer includes an AC/DC power supply suitable for
use with 24VDC, 120VAC and 240VAC. When AC powered, the Omni 3000
provides a maximum of 650mA at 24VDC for powering the transducer loops.
The Omni 6000 provides a maximum of 500mA at 24VDC.
