【英文介绍】

Allen-Bradley 1756-IR6I is a temperature measurement simulation module. This is an analog module for resistance temperature detector (RTD) sensors.

The 1756-IR6I module provides two data formats, integer mode and floating-point mode. When selecting integer mode, integrated features include multiple input ranges, notch filters, and real-time sampling. The floating mode includes all of these features and adds temperature linearization, process alarm, rate alarm, and digital filtering. It also has selectable temperature units, such as degrees Celsius or Fahrenheit. The module has four (4) possible input ranges, including 1 to 487 m? , 2 to 1000 m? ; 4 to 2000 m? ; , and 8 to 4000 m? ; . These ranges specify the minimum and maximum signals that the module can detect. It has six (6) independently isolated RTD inputs with a resolution of 16 bits. The actual resolution includes 7.7 m of 1-487 ohms. bit; 2-1000 ohms are 15 m/bit, 4-2000 ohms are 30 m/bit, 8-4020 ohms are 60 m/bit. Module notch filter line noise filtering. Make sure to select a filter that closely matches the expected noise frequency of the application. Digital filters smooth the data by eliminating noise transients on each input channel.

The 1756-IR6I's real-time sampling feature allows the module to collect multicast data by scanning all of its input channels. To enable multicast, configure the real-time sampling (RTS) period and the requested Packet Interval (RPI) period.

Protection features are also embedded in the module, such as underrange/overrange detection, which is used to monitor whether the input signal exceeds the limits set in the input range. Process alerts work similarly, but process limits are set manually by the user. Integrated rate alerts allow the module to detect rapid increases or decreases in a short period of time. Rate alarms are only available in applications that use floating point. The break detection function provides loop connection integrity. It can detect whether RTB or wires in the module have been disconnected.

Small offset errors in the 10 ohms copper RTD can be compensated by the module's 10 ohms offset function. You can also configure sensor types for each channel in the module. This linearizes the analog signal to a temperature value.

The Allen-Bradley 1756-IR6I is a ControlLogix module for receiving signals from a resistance temperature detector (RTD). This module belongs to the analog input category and is particularly used for temperature measurement applications.

It accepts resistance signals from RTD types such as platinum 100, 200, 500, 1000? Alpha =385; Platinum 100, 200, 500, 1000? Platinum, alpha=3916; Nickel 120? alpha=672, nickel 100, 120, 200, 500? alpha=618 and copper 10? . The module is compatible with 3-wire and 4-wire RTDS. RTDS function by providing a specific output resistance at a specific temperature. The RTD table is used to identify the corresponding resistance output. When using this module, the selected RTD type is selected to ensure that the module is functioning properly.

The conversion of the module input signal to the user depends on the defined range. For 1-487? , low signal and user converts to 0.859068653? And -32,768 counts, while the high signal and user conversion rate is 507.862? And 32,767 counts. For 2-1000? Two? -32768 count and 1016.502? 32767 counts, for 4-2000? 4? -32768 counts and 2033.780 sums? 32,767 counts. And then it's 8-4020? - Eight? - Is 32,768 count and 4068.392? It's 32,767 counts.

The module has an overall input resolution of 16 bits. In practical measurements, this equates to 7.7 m? /bit, 1... 487? ; 15 m? /bit for 2... A thousand? ; 30 m? /bit for 4... Two thousand? And 60 m? /bit for 8... 4020? .
