The single analog input D1000 and D2000 series modules operate on a single power supply input
from 10 to 30 Vdc. They provide an isolated 15-bit measurement A/D converter and discrete digital I/O bits
for controlling solid state relays or sensing contact closures. The number of digital
inputs and outputs varies depending on module type. The module performs A/D conversion and linearization
of sensor input data. The module transmits data values in ASCII
format to any host computer with a standard RS-232 port.
Modbus RTU protocol is widely accepted and
supported by all major process
control programs. Users of process control software packages or users of Modbus
protocol should consider the 'D1000M' series. The D1000M series is
the D1000 series modules. The appended letter 'M' means that the module can communicate using the
'RTU' version of the Modbus protocol in RS-485. The D1000M series
data sheet contains a complete list of model numbers.
The four analog input D5000 Sensor to Computer Modules are a
solution designed for data acquisition systems based on personal computers and other
processor-based equipment. The modules provide direct connection to four analog signals of
the same type and range. A/D conversion and linearization of sensor input data is
performed with the module and data values are transmitted in ASCII format to any host
computer with a standard RS-232 port.
