QX81

The QX81 is an innovative, lightweight DC input module crafted by Mitsubishi for general industrial purposes. Boasting a weight of only 0.16 kilograms with LED operation indication, this model provides reliable performance in any environment.

The QX81 LED indicator is a reliable way to stay informed of the module's activity, with its IP2X protection class providing an extra layer of security. A cable connection requires wires between 0.088 and 0.3 mm2 in core diameter for seamless integration into other systems.

Technical Specifications of QX81:

The QX81 model accepts signals from various sources - 32 input points, with an external connection via its 37-pin D sub connector by 24 VDC and 4 mA. This module features an adjustable response time for noise resistance; the pulse width can be adjusted accordingly.

The model QX81 is an isolation technique incorporating a photocoupler input module with distinct characteristics. This technology emits 11 V of voltage with 1.7 mA of current when OFF while boasting 10 Mohms insulation resistance for greater reliability in operations.

In addition, the noise immunity makes it more resistant to external disturbances due to its 500Vp-p noise voltage rating and maintaining peak performance at only 1-microsecond pulse width for maximum efficiency under all conditions.

To limit the potential impact of noise, carefully manage input response times when utilizing the QX81 model. This module is designed to withstand a dielectric voltage of 560 VAC and operate in altitudes up to 2000 meters.

The QX81 model boasts impressive reaction times of 10 milliseconds for both OFF-to-ON and ON-to-OFF transitions, configurable with a PLC parameter. It has an extensive common terminal offering 32 points capacity and operates on 19 V minimum voltage while requiring only 3 mA current to maintain its On state.

The DC input module, model QX81, is a reliable power source with an internal current usage of 75 mA when all 32 points are active. Its 5,600-ohm impedance provides strong connectivity for compatible A6CON1E through A6CON3E (optional) connectors.

Software and Settings

GX Developer allows precise adjustments of the QX81 module's parameters. Select "Input" or "I/O" from the Type drop-down menu to access the Input/Output assignment tab and adjust response times through a range of options by accessing its Detailed setting button.

Standard Installation and Wiring Guidelines:

After you have finished the wiring, put the metal cover on the QX81 so that you can protect yourself. Ensure no external power is connected first to protect yourself from receiving an electric shock while removing or installing this module.

The QX81 DC input module is a sensitive component that could be irreversibly damaged if certain precautions are not taken. When wiring the unit, ensure properly rated voltage and terminal layout to avoid power source or connection errors that may result in catastrophic failure.

The QX81 module is simple to mount; all that is required is to press the lever on its underside, then slide the module's fastening projection into place until it clicks into position. After installing the necessary components, you can safely insert them into the module. When handling, exercise extreme caution because electrical and conductive components may come into contact with the skin.
