ITP11 Loop-powered indicator 4..20 mA

The lifetime is 8 years, and the MTBF is 80,000 hours.

If the decimal point position has been set to 0, and the current calculated value is, say, 1.7, the display will read 1, i.e. the value will be truncated.

The ITP11 supports any 4-20 mA signal from any piece of equipment with an output of this kind. The connection should be performed in series.

That depends on the output, whether it is a passive or an active one. For example, the analog outputs of our Programmable Relay PR200 are passive outputs, meaning that any of them requires an external voltage source. In case of an active analog output, no external voltage source is required.

The number of the connected displays depends on the available supply voltage because each ITP11 causes a voltage drop of about 4 V. For example, an external voltage source of 24 V connected to a 4-20mA analog output of a Programmable Relay PR200 supports up to 5 ITP11 displays (without any other loads).

The connection should be performed in a series circuit.

First of all, check the polarity of the signal.

Also, make sure that the 4-20 mA signal is available. If the signal is too low (< 3.8 mA), there is not enough power to switch on the process display.

Check the wiring. A wire may be loose or not connected to the terminals.

Check the transmitter output. If the output is passive, you need an auxiliary voltage supply.

No, you cannot do it. The ITP11 supports only 4-20 mA.

For a 0-10 V signal, you can use our Universal Process Indicator ITP14.

For a Pt100 signal and many other signals for temperature measurement, we offer the Temperature Display ITP16.

Please feel free to contact us if you need support.

The ITP11 doesn’t require auxiliary power and is supplied directly from the current loop.

You don’t need any software to program the ITP11. The programming is carried out by using three buttons on the ITP11’s cylindrical body.

Please, watch our video tutorial ‘ITP11 Process display 4-20 mA. First Start’ to get more information.

Technically, it doesn't matter; but in terms of convenience, it depends on your particular case.

To scale the measuring limits, please proceed as follows:

- Connect the device to a 4-20 mA signal to provide power.

- Hold down the PROG button for at least 3 seconds to access the parameter menu.

- When the display shows ‘0’, enter the password “5” using the UP and DOWN buttons. The same buttons are used for navigating the menu.

- Once you access the menu, the word “PS” will appear. Navigate the menu to find the parameter ‘di.Lo’ and press the button PROG to access it.

- Set the required value and press PROG to save it and exit.

- Proceed the same procedure for the parameter ‘di.Hi’.

To exit the parameter menu, hold down the button PROG for at least 5 seconds.

Please, watch our video tutorial ‘ITP11 Process display 4-20 mA. First Start’ to get more information on programming the device.

The lower measuring limit (the parameter di.Lo) should be set to 0.

The upper measuring limit (the parameter di.Hi) should be set to 100.

To set the alarm limits please proceed as follows:

- Connect the device to a 4-20 mA signal to power it

- Hold down the PROG button for at least 3 seconds to access the parameter menu

- When the display shows ‘0’, enter the password '5' using the UP and DOWN buttons. The same buttons are used for navigating the menu.

- Once you access the menu, the word ‘PS’ will appear. Navigate the menu to find the parameter ‘d.FnC’ and press PROG to access it.

- Select the required alarm logic (see the figure below) and press PROG to save it and exit

- Navigate the menu to find the parameter ‘SP.Lo’ and press PROG to access it

- Set the required lower setpoint limit and press PROG to save it and exit

- Do the similar procedure for the parameter ‘SP.Hi’ (upper setpoint limit)

To exit the parameter menu hold down PROG for at least 5 s.

Please, watch our video tutorial ‘ITP11 Process display 4-20 mA. First Start’ to get more information on programming the device.

No, you cannot do this. The Process Display ITP11 isn’t equipped with an output, and its alarm function isn’t implemented by means of an output. This function just makes the display blink when the process value is outside or within the previously-set limits.

If there is required an output signal to trigger a relay, you can use our Universal Process Indicator ITP14.

Please feel free to contact us if you need support.

The password cannot be changed. However, it can be disabled. Just enter the parameter menu and set the parameter ‘PS’ to ‘OFF’.

Proper device installation (see User Guide) warrants protection against dust and water (IP65 on the front). Because of the exposed terminal block, the rear part of the enclosure is rated much lower – IP20.

Since the current flowing through the ITP11’s input tends to vary from 4 to 20 mA, the input resistance changes inversely proportionally to it. For the sake of convenience, we declare the maximum voltage drop (4 V) instead. Of course, you can use this voltage to calculate the input resistance depending on the current if needed.

The enclosure is only available in grey color. The LEDs can be ordered in red or in green color.

The maximum cross section of a solid conductor is 1.5 mm².

The maximum cross-section of a stranded conductor is 0.2 – 0.75 mm².

The accuracy is 0.2 % + 1 digit.

The sample time is 1 second.

There is no overload protection at the ITP11 input, so please ensure that the input current is lower than 25 mA.

The maximum recommended distance is 100m. However, we recommend keeping it as short as possible because the resistance of a long conductor can affect the signal value.

The device is designed for panel mounting in a borehole of Ø22.5 mm (see User Guide, Appendix A).

The ePLAN 3D model is available under the tab ‘DOCUMENTS AND SOFTWARE’ on the product page. There is also a STEP model available under the same tab.

The ITP11 Process Indicator can be set for either direct or inverse proportionality:
