The D3000 and D4000 computer-to-analog output
interfaces are designed to be mounted remotely from a
host computer and communicate with standard RS232
and RS485 serial ports. Simple ASCII commands are
used to control a 12-bit digital-to-analog converter that
is scaled to provide commonly used current and voltage
ranges. An on-board microprocessor provides the
communications interface and many intelligent analog
output functions. These modules offer an extremely
flexible, easy-to-use, and cost-effective approach to
data acquisition.
The D3000 and D4000 are compatible with the
OMEGABUS
®
D1000 and D2000 and may be used in
any combination. Up to 124 modules may be strung
on one set of wires. All modules are supplied with
screw terminal plug connectors and captive mounting
hardware. The connectors allow system expansion,
reconfiguration, or repair without disturbing field wiring.
Their small size allows them to be mounted in virtually
any location or position including explosion-proof
housings and DIN rails. Utility software (D1000-SW) is
available for free download.
The D4000 modules offer several additional features.
A slew rate may be programmed, which causes the
output to ramp at an adjustable rate in either an
increasing or decreasing direction. The ramp can
be initiated and maintained by commands from the
computer or with external switch closures to the
module. The D4000 module provides a readback
feature which allows the computer to verify the integrity
of the output.
The D4000 modules also include a watchdog timer
circuit that can be set such that if the computer fails
to communicate with the module after a preset time
period, the module will reset itself to an adjustable
default value. This feature minimizes the risks of
communication failure.
The A1000 RS232 to RS485 converter and repeater
can be used if an RS485 port is not available in your
PC, and it is necessary to communicate long distances
away. The A1000 also provides power for the modules.
RS232 modules can be used for distances less than
15.2 m (50').
