Yokogawa RIO4000 Data sheet

RIO4000 Sensor Model

General Specifications

The RIO4000 is the RTD measure and simulate module for the Yokogawa accurately measures or simulates the resistance of 22 different RTD sensor types with nominal resistance to 4000 ohms. 2-, 3-, and 4wire RTDs are supported and RTD material may be platinum, copper, nickel or iron. Several alpha coefficients are supported per Table 1 on page 2. The module can simulate temperature to all conventional or smart RTD transmitters and signal conditioners including those utilizing pulsed excitation current.

The YPC converts measured resistance to a corresponding temperature value and displays the value in the user-selected temperature unit (°F, °C, °R or °K). Ohms can also be displayed for direct reading or troubleshooting assistance. Pt 100 RTDs are available from Yokogawa for use with the module. These 4-wire, DIN Class A probes come complete with handle, 5’ coiled cable, and connector. Accessory connectors are available to connect to any RTD or RTD transmitter for temperature measurement or simulation needs. Simulations are supported through setup controls that allow the user to enter a specific temperature, a range of temperatures stepped through with manual or automatic advance or a temperature range with automatic ramping advance for a selected time period.

Field recalibration of the module is provided by the YPC’s “Rcal” feature. “Rcal” can be used to re-calibrate the module alone or the module with dedicated RTD for “match set” accuracy. The module + RTD option provides the best possible measurement accuracy for the most demanding measurement applications.

The RIO4000 and a dedicated DIN Class A RTD makes an excellent temperature reference standard for comparison to RTDs installed in process applications. The RIO4000 and user cable

provides convenient RTD measurement and simulation capability.

Table 1: Supported RTD Materials / Nominal Resistance

The adjacent table lists the RTDs supported by the RIO4000 module and YPC 4000 Series. Materials, types and alpha coefficients are based on popular RTDs used in the field.

Yokogawa offers Pt 100 accessory probes that are automatically recognized by the RIO4000 module. No set up is necessary on the YPC. Users can configure their own reference RTDs similarly by using the accessory connector and Rs resistor (Probe ID resistor listed in adjacent table) to connect their RTD. This technique allows the module to automatically recognize the connected RTD and recall its characteristics. If no Rs resistor is used, a copper wire must be installed in its place. This causes an RTD selection menu to automatically appear on the YPC display, enabling the user to configure the YPC for use with any supported RTD type.
