The Mitsubishi QX70H represents a reliable solution within the Melsec-Q series as a DC input module, specifically designed with a positive common configuration. This module accommodates 16 input points, making it suitable for extensive input signal management in various applications. Its rated input voltage is precisely set at 5 V DC, with an acceptable variation of +20% to -15%. The ripple ratio is limited to a maximum of 5%. The current consumption is noted at approximately 6 mA, ensuring efficient power usage.
In addition, the QX70H allows for a maximum of 16 simultaneous input points, making it highly functional for concurrent operations. To register an ON state, the module requires a voltage of 3.5 V or higher and a current of at least 3 mA. Conversely, lower thresholds signify an OFF state, with maximum allowances of 1 V for voltage and 1 mA for current. The input resistance is around 470 Ω, facilitating reliable signal processing.
The input terminal arrangement consists of 16 points sharing a common connection. Interrupt functionality is integrated, enhancing the module's responsiveness to specific conditions based on user configuration, which can be adjusted via the CPU parameter switch. The protection degree of IP20 signifies that the module is safeguarded against dust, although it should not be exposed to direct water contact.
Operation status is visually indicated through an LED signal. The external interface is an 18-point terminal block secured by M3 screws, providing straightforward connections. This module occupies 16 I/O points within the system, making it a compact yet powerful addition to the Mitsubishi automation lineup.
