• Resistor module (model: REM3-250) Though the REM3 is designed to be mounted directly to this model, we recommend that it be attached to a separate terminal board in order to eliminate its heat conduction to affect the cold junction compensation and the overall measuring accuracy of this model.
• RZXS configurator software (model: RZMSCFG) Downloadable at M-System’s web site. A dedicated cable is required to connect the module to the PC. Please refer to the internet software download site or the users manual for the PC configurator for applicable cable types. PACKAGE INCLUDES...
• PC Recorder Software CD
• USB cable (1 m or 3.3 ft) GENERAL SPECIFICATIONS Connection USB: USB type B connector, female RS-485: Euro type connector terminal (Applicable wire size: 0.2 – 2.5 mm2 (AWG24 – 12), stripped length 7 mm) I/O: M3 screw terminals (torque: 0.6N·m) Grounding: M4 screw terminal (torque: 1.2N·m) PC Configurator: Miniature jack, RS-232-C level Screw terminal: Nickel-plated steel Housing material: Flame-resistant resin (gray) Isolation: Input 1 to input 2 to input 3 to input 4 to input 5 to input 6 to input 7 to input 8 to input 9 to input 10 to input 11 to input 12 to trigger input to alarm output to USB or RS- 485 or configurator jack to ground Zero/span adjustments: Available with PC Configurator Software for all types of inputs. Burnout for T/C and RTD input: Upscale, Downscale or No burnout selectable Select ‘No Burnout’ to minimize the measuring errors caused by the sensor/wire resistance and the burnout sensing current. With RTD input, the signal may go transiently to the opposite direction from the burnout setting. With DC/potentiometer input, the burnout setting is ignored and the burnout sensing current is cancelled. In order to specify burnout actions to individual channels, use PC Configurator Software. Wire resistance compensation for RTD input: Field calibration for 3-wire (or 2-wire) RTD available with PC Configurator Software. Cold junction compensation (CJC) for T/C input: CJC can be enabled or disabled. Reference temperature is measured at the internal sensor by factory setting. In order to specify cold junction compensation to individual channels, use PC Configurator Software. Temperature measured at another channel of this model can be specified as the reference point by using PC Configurator Software. This is beneficial to reduce compensation wires’ cost when there are many temperature points in remote locations. Install a relaying terminal board near the sensors and use ordinary copper wires between the board and this model, and assign one channel to measure temperature at the terminal board as the reference. Operating mode setting: Rotary switch; burnout type, cold junction compensation, line noise frequency, software filter, A/D conversion mode, service channel numbers setting

MODEL: RZUS-U9 RZUS-U9 SPECIFICATIONS ES-7622 Rev.10 Page 2/10 http://www.m-system.co.jp/ available Line noise filter: NMNR ratio to the line frequency and its harmonic contents can be optimized. Factory set to 50/60 Hz mode for use with both frequencies. Select either frequency for the most effective result. Programmable first order lag filter: Time constant selectable with PC Configurator Software. The use of this filter is disabled at the factory shipment. With the large time constant setting, measured signals during the warm-up immediately after the power is turned on may affect the signals for a long time period. A/D conversion mode: Fast, Medium or Slow selectable with PC Configurator Software. With Slow setting, data fluctuations are minimized with limited sampling time (speed). With Fast setting, sampling time (speed) can be high though data fluctuations increase. Node address setting: Rotary switch; 1 – F (15 nodes) Indicator LEDs: Five (5) LEDs indicate the module’s operating conditions. Service channel numbers: 12 channels (ch.1 thr. 12) or 6 channels (ch.1 thr. 6) are selectable with PC Configurator Software. Factory set to 12 channels.

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 mV AC superposed on a thermocouple or ±60 mV input. Common mode noise rejection Magnitude of the effects of voltages applied across the terminal C and the ground terminal when there is no potential difference among all the C terminals. DC: N/A AC, ±3 V, ±6 V, ±12 V: Approx. 86 dB AC, other ranges: Approx. 120 dB Common mode noise rejection between channels: Magnitude of the effects of DC/50/60 Hz voltages applied across the terminals C of the present and the last scanned channels. (Data are scanned from ch 1 to ch 12 in turn and back to ch 1 again.) DC, ±3 V, ±6 V, ±12 V: Approx. 100 dB DC, other ranges: Approx. 120 dB AC, ±3 V, ±6 V, ±12 V: Approx. 86 dB AC, other ranges: Approx. 106 dB High common mode noise between channels may compromise the accuracies in low millivolts measuring including thermocouple input. We recommend that C terminals of each channel be cross- wired and then connected to the ground terminal to ensure the measurement of the highest accuracy. If such configuration is not possible, take special consideration to minimize the channel-to-channel common mode noise and the potential against the ground terminal. The potential of the open terminal C against the ground terminal equals to that of the last scanned channel. If ch 2 and ch 3 are not connected, the accuracy of ch 4 measurement is affected by potential difference between the C terminals of ch 1 and ch 4.

• Downscale Burnout ■ RTD INPUT ■ POTENTIOMETER INPUT *1 Input Connection Examples *2 When the device is located at the end of a transmission line via twisted-pair cable, (when there is no cross-wiring), close across the terminal T2 – T3 with the attached jumper pin (or with a leadwire). When the device is not at the end, remove the jumper pin. In order to prevent instability in measured values caused by noise entering through the I/O terminals or RS-485 connector, to protect the unit from malfunction and failure, to protect the operator from electrical shock, grounding the RZUS-U9’s GND terminal to a most stable earth point in the environment is recommended. If the PC is equipped with an earth terminal, grounding it to the same point is also recommended. Be careful to eliminate noise as much as possible by e.g. using shielded cables. Ground the signal shield to a most stable earth point in the environment. Separate USB and RS-485 cables as far from power supply or other field wiring which may be a noise source. Certain types of PC, susceptible to noise interference through USB cable, easily freeze. The smaller is common mode voltage (DC and AC) between C terminals and between C and GND, the better is measuring accuracy. Connecting between C terminals and if possible to GND will yield the best accuracy. Resistor modules (model: REM3-250) can be connected to 1A through 12C terminals to convert current inputs into voltage. However, it is not recommended when TC inputs are mixed because the heat developed on and around the REM3 affects the cold junction compensation performance. We recommend that REM3 be connected on a separate terminal board. When the internal temperature sensors are used for CJC, temperature imbalance around the terminal block affects greatly the CJC accuracy. In order to minimize such imbalance, do not use wires of large diameter which has large heat dissipation. Be sure to close the terminal cover. Do not expose the module directly in the line of wind from a cooling fan. Two-wire RTD can be used by closing across B and C terminals. Be sure to compensate wire resistance by PC Configurator Software. Note 1: Note 2: Note 3: Note 4: Note 5: Note 6: Note 7:
