DIN Rail Mount Digital Signal Conditioners With RS-485 Communications Models Available for Thermocouple, RTD, Process Voltage, Strain, Frequency, Pulse, ac Voltage, and Current Microprocessor-Based Design 1800 V Isolation Up to 16-Bit Measurement Resolution (Model Dependent) RS-485 Communications
The DRX Series digital signal conditioners provide a complete sensor-to-computer solution. The intelligent microprocessor-based modules accept a variety of input signals and produce an RS-485 output signal that may be sent to a computer or virtually any other instrument containing a serial port. The modules offer a wealth of features including a diverse range of input types, configurable operation, networkable communications, and electrical isolation. Models are available for most process signals including thermocouples, RTDs, process voltage, process current, strain, frequency, pulse, ac voltage, and ac current measurement. The DRX Series digital conditioners provide an effective, easily implemented means of automated data monitoring for either laboratory or industrial applications.
