Model RZUS-U9 is a high performance 12-point universal input module designed for remote I/O and data acquisition applications. The Modbus RTU protocol enables interfacing with the PC Recorder software, MSRPAC-2005.

Model RZUS-U9, designed to be powered through the USB cable, is ideal for mobile use with its flexible input capabilities just like the model RZMS-U9. It conforms to Full Speed USB 2.0, fully hot-swappable by meeting the standard’s strict inrush current limitation, and applicable to the PC’s power saving control (low energy consuming ‘Suspend’ mode).

A 500 Vpeak channel-to-channel isolation plus isolation between external trigger input, communication ports and alarm contact output is provided.

The RZUS-U9 features superb noise filtering capabilities for 50/60 Hz line. NMNR ratio to the line frequency and its harmonic contents can be optimized by setting the rear DIP switch. Each input circuit has a CR filter of sufficient large time constant so that there will be little effect of line noise such as 500 mVac superposed on a thermocouple or ±60 mV input.

The PC Configurator software RZMSCFG features CJC to individual channels, programmable first order lag filter, selectable burnout for T/C and RTD input. Others include Modbus communication parameter, hardware information, continuous input monitoring, zero and span trimming, leadwire resistance compensation for RTD input, and etc.

• Supports 13 TC types, 12 RTD types, potentiometer
  and ±12 Vdc inputs (current input with resistors)
• 500 Vpeak isolation between each analog input, trigger, power and alarm
• Includes both RS-232C and RS-485 communication ports
• Excellent noise rejection ratio for stable and accurate
  measurement in extreme environments
