The INFINITY®
Series DIN rail mount signal conditioners represent state-of-the-art signal
conditioning technology, ideal for all process and power monitoring applications.
The intelligent microprocessor based modules provide a wealth of features
including, high accuracy inputs, field programmable ranges and 3-way electrical
isolation. Models are available for most process signals including thermocouples,
RTDs, process voltage, strain, frequency, pulse, ac voltage and ac current
measurement. Two base styles are available, the DRN series which provides
an output in an analog voltage or current format, and the DRX series which
provides a digital RS-485 output.
DRN SERIES ANALOG OUTPUT
The DRN Series are the perfect front-end for a PLC or data acquisition
system. They feature an analog output signal which is directly proportional
to the input signal. The output, which is scalable, may be set for 0-10
V, 4-20 mA or 0-20 mA. The module is easily configured for different operating
parameters by connecting to a standard PC serial port and using the DRN-CONFIG
Windows-based software package. Once the module is configured, the parameters
are saved in non-volatile memory. The unit may be disconnected from the
PC and only needs to be connected to a PC again if an operating parameter
is to be changed.
DRX SERIES RS485 SERIAL OUTPUT
The DRX Series provide a complete sensor-to-computer solution. The modules
accept a variety of input signals and produce a RS-485 signal that may
be sent to a computer or virtually any other instrument containing an
RS-485 serial port. The DRX series may be used to create a comprehensive
distributed process monitoring network. Up to 32 modules may be interconnected
over a distance of 1200 m (4000 ft) on a single pair of wires. Through
the use of optional RS-485 repeaters, additional modules and distances
are easily accommodated. With repeaters, up to 254 modules may be connected
to a single RS-485 port. The modules feature a powerful, easy-to-use ASCII-based
command set. Because communication is accomplished by simply reading and
writing to and from the computerÆs serial port, a program may be developed
using any language that provides serial port support. No special software
drivers or libraries are required.
