What Is in This Chapter? This chapter contains the following topics: These modules offer the following ranges for each input, according to the selection made at configuration: Presentation These modules offer the following ranges for each input, according to the selection made at configuration: In this case, only one sensor is needed.
The last digit represents 0.

For millivoltmeter, the data ranges from 40 mv, mv to mv and is also a multiple of 10 of the real measurement. The last digit represents 10 nv. For millivoltmeter, the data range of mv is a multiple of of the real measurement. The last digit represents nv. A layer of multiplexing allows self-calibration of the acquisition device offset, as close as possible to the input terminal, as well as selecting the cold junction compensation sensor included in the TELEFAST housing.
A current generator ensures the RTD resistance measurement. There is a converter for each input. Measurement Filtering The type of filtering performed by the system is called “first order filtering”. The filtering coefficient can be modified from a programming console or via the program. The mathematical formula used is as follows: This value may be changed even when the application is in RUN mode.

Filtering may be accessed in Normal or Fast Cycle. The filtering values are as follows. They depend on the sensor type. T is a cycle time of ms for TC and mv. T is also a cycle time of ms for RTD and Ohms. Sensor Alignment The process of “alignment” consists in eliminating a systematic offset observed with a given sensor, around a specific operating point. This operation compensates for an error linked to the process.
Therefore, replacing a module does not require a new alignment. However, replacing the sensor or changing the sensor s operating point does require a new alignment. Conversion lines are as follows: For each input channel, you can: The alignment offset may also be modified through programming. Channel alignment is performed on the channel in standard operating mode, without any effect on the channel s operating modes.
Given that there are a large number of channels, a cable of at least 10 twisted pairs is used, with general shielding outside diameter 10 mm maximumfitted with one or two male pin FCN connectors for direct connection to the module. Connect the cable shielding to the grounding bar. Clamp the shielding to the grounding bar on the module side.
Failure to follow these instructions will result in death or serious injury. Using the Sensors Isolated from the Ground The sensors are connected according to the following diagram: It is therefore essential to follow the following rules: You must therefore check that all leakage currents generated do not disturb the system.
Sensors and other peripherals may be connected to a grounding point some distance from the module. Such remote ground references may carry considerable potential differences with respect to local ground. Induced currents do not affect the measurement or integrity of the system. Electromagnetic perturbations may lead to an unexpected behavior of the application.
Plugging the wrong connector would cause an unexpected behavior of the application. Failure to follow these instructions can result in death, serious injury, or equipment damage. RTD probe current generator – output: It is not connected if the sensor type is LM This device provides a voltage in mv corresponding to: The overall margin of error when using this device is reduced to 1.
Channel 0 is thus dedicated to the cold junction compensation of channels 1, 2 and 3. It is also possible, by using a 2-wire Pt probe, provided the initial length of the probe is limited, to maintain channel 0 as a thermocouple input.
The wiring would then look like this: The wiring is only valid if the channel 0 is used. If the channel 0 is not used, select a cold junction with external Pt The range of the channel 0 is changed to a 3- wires Pt probe.
It is not necessary to wait 45 mn if the compensation is performed by an external Pt probe. Operating in TC mode with cold junction compensation using a 2-wire PT probe. Operating in TC mode with cold junction compensation using a 3-wire PT probe. User Manual Contents Document information Overview Analog inputs For connection of voltage and current sensors, thermocouples, resistors and resistance s Application Analog input modules can be used to connect the PLC to analog process signals.
The reliability of a power supply must match or exceed the rest of the system in which it is installed. Accepts inputs of between 20 mv to V rms to give. The output channels may be.
If you don t find answers to your questions here, you can send a specific question. Sam Herceg sherceg pyramid. Connecting Grounded and Aart Thermocouples For best performance, Thermocouple sensors should be floating.
This will ensure that no noise currents can flow in the sensor leads and that no common-mode. The sensor measures temperature, and the measurement is interfaced into an ADC selected by the systems. The module offers 4 PT inputs.
