Newport DIN-Rail Mount Signal Conditioners ---

The DRN/DRX 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, as well as RS-232, 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 computer’s serial port, a program may be developed using any language that provides serial port support. No special software drivers or libraries are required.
