X80 1052 溫度和過程變量監視器
The Ronan Series X80-1052 Temperature and Process Signal Indication System is designed to monitor temperatures from thermocouple and Resistance Bulb inputs as well as engineering units from voltage and current sensors used in industrial applications. The units may be supplied for standard flush mounting in control panels or standard EIA relay racks.
Each system consists of a master module and a number of sixteen point switch modules （up to a maximum of six） making a total of ninety-six points that can be monitored with one unit. In addition, a plug-in power supply module is available to handle 115 VAC power supply requirements. Each switch module is complete with a sixteen-point membrane-switch matrix and input signal amplifiers with interlocking electronic circuitry to prevent addressing of more than one input simultaneously.
Any given switch module accepts any of the standard RTD's, Thermocouples, or Process signal inputs. Two types of input signals can be grouped in each switch module. Therefore, 100 Ohm and 120 Ohm RTD's can be handled by the same switch module, for example, as well as, type E and J Thermocouples, or 4-20 mA and 1-5 VDC, etc.
The master module is complete with a four-digit panel meter, signal conditioning, and up to three linearizing amplifier modules. The linearization amplifier optimizes the read-out accuracy of non-linear sensor inputs such as RTD's and thermocouples. Switch modules using linear inputs require only one linearizer amplifier. Each range is achieved by adjusting zero and span on the input amplifiers provided in each sixteen-point switch module. The digital meter permits reading temperature in degrees Celsius or Fahrenheit, selectable by a front panel mounted push-button switch. Engineering Unit readouts are automatically displayed and identified with the suffix "E" on the digital display. The display can be scaled to present any readout within the digital display range.
