FAQ

    FAQ

    What type of signal does the Universal Process Indicator ITP14 support? How should I connect it?

    The ITP14’s input can be set up to any of the following signal types:

    current: 0-5 mA, 0-20 mA or 4-20 mA

    voltage: 0-10 V or 2-10 V.

    The way you should connect your sensor to the ITP14 depends on the output signal of this sensor:

    Rate the answer?
    Can I connect the ITP14 to an analog 4-20 mA or 0-10 V output directly?

    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.

    In case of an active analog output, no external voltage source is required.

    4-20 mA / 0-10 V connection to a passiver/active output

    Please note, the ITP14 must be powered by 24 V DC in both cases.

    Rate the answer?
    Can I connect several Process Indicators ITP14 to the common analog output? How should I connect them, in series or in parallel?

    Yes, you can do this.

    The connection depends on the input signal:

    Current (4-20 mA, 0-5 mA or 0-20 mA) – serial connection; the maximum number of displays depends on the available power, each ITP14 consumes 1W;

    Voltage (0-10 V or 2-10 V) – parallel connection; the maximum number of displays depends on the available load current.

    Rate the answer?
    I have connected the ITP14 but it doesn’t switch on, what should I check?

    The ITP14 requires an auxiliary voltage of 24 V DC, so please ensure you have provided it.

    If the display still doesn't function, check if the polarity of the voltage connection is correct.

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