Mitsubishi presents the QX50, a dedicated PLC input module designed for integration into the Melsec-Q series. This module allows for 16 digital channels, utilizing 16 I/O points on the connected PLC. It is rated for an input voltage of 48 V AC/DC, accommodating a wide voltage range from 40.8 to 57.6 VDC and 40.8 to 52.8 VAC, enhancing its adaptability for different installations.
With an approximate input current of 4 mA per channel, the module efficiently responds to operational changes. The minimum voltage and current required to trigger the ON state are ≥ 28 V and ≥ 2.5 mA, while conditions for an OFF state are ≤ 10 V and ≤ 1.0 mA. The response times are also noteworthy, with a rapid transition from OFF to ON accomplished in ≤ 5 ms, and a delay of ≤ 20 ms for switching from ON to OFF.
Configurability is a highlight of the QX50; it allows users to select between positive and negative common for the input type. To ensure safety and reliability, the module implements a photocoupler for insulation. Dimensions are compact, measuring 27.4 mm in width, 98 mm in height, and 90 mm in depth.
Operating conditions are optimized, with this module functioning efficiently in temperatures ranging from 0 to 55°C. Compliance with multiple certifications, including CE, UL/cUL, EAC, UKCA, ABS, and others, ensures that the QX50 meets international safety and performance standards.
