The D3000 and D4000 computer-to-analog output
interfaces are designed to be mounted remotely
from a host computer and communicate with
standard RS-232 and RS-485 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 upon request at no charge on an
IBM-compatible disk.
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 RS-232 to RS-485 converter and repeater
can be used if an RS-485 port is not available in your
PC, and it is necessary to communicate long distances
away. The A1000 also provides power for the modules.
RS-232 modules can be used for distances less than
50 feet.
