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 three dual channel serial
I/O modules. If the number of combo modules required, including spare I/O, 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.
'A' modules provide four input channels, two selectable as analog only input channels.
The third and fourth input channels are selectable analog or meter 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. Two analog
outputs are provided.
'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,
Daniel,
Instromet, FMC,
Kongsberg, and
SICK ultrasonic devices for liquid applications
only. There are six analog 4-20 mA outputs provided.
'HT' modules provide four
HART networks for use in a point-to-point configuration.
Two analog outputs are provided.
'HM' modules provide four
HART networks for use in a multi-drop configuration or for
use with multi-variable transmitters. Two analog outputs are provided.
To determine the total number of combo modules (Types 'A' + 'B' + 'E' + 'E/D' +
'H' + 'HV' + 'SV' + 'HT' + 'HM') 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', 'SV','HT',
or 'HM' modules are 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.
The OMNI 3000 is limited to one dual serial or serial ethernet I/O module. The OMNI
6000 can accept up to three serial I/O modules of which 2 can be serial ethernet.
The first port can be configured for a printer or Modbus™. All six ports 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 three communication channels. Channel
one is an RS-232/RS-485 serial channel, channel two is a 10BaseT Ethernet channel
and channel 3 is an RS485 repeatable port to connect to any Modbus device.
The computer includes a universal input AC/DC power supply suitable for use with
100-250 VAC or 24VDC. When AC powered, the OMNI 3000/6000 provides a maximum of
750mA at 22-26VDC for powering the transducer loops.
Application firmware revision numbers must be specified.
Firmware is available either in US or metric customary measurement units for liquid
or gas applications.
