The Mitsubishi AX71 source input module is engineered to handle 32 distinct input points. It supports multiple input voltage options of 5, 12, or 24 VDC. The use of a photocoupler for insulation ensures separation between input and control circuitry, improving system reliability.

Maximum input currents vary by voltage level, with specifications of 5.5 mA at 5V DC, 3 mA at 12V, and 6 mA at 24V. The operational characteristics are defined by a switch-on voltage from 4.5 to 5.5 VDC, while the switch-off voltage ranges from 10.2 to 26.4 VDC. This enables precise control and interaction with connected devices.

Regarding input impedance, the values are 1.4 KOhm when turned on and 5.5 KOhm when off, allowing efficient signal processing. The response times for action are quick, with a maximum of 3 milliseconds for switching from on to off and 1.5 milliseconds for off to on transitions. Additionally, each input point is equipped with an indicator LED for convenient status monitoring.
