The Mitsubishi FRA7AL is a key component within the FREQROL FR-A7 series, tailored for advanced motor control applications. This unit can receive significant input pulse frequencies, with the differential line receiver supporting up to 500 kpps and the open collector mode reaching 200 kpps. Configuration flexibility is provided through electronic gear settings ranging from 1/50 to 20.
Permissible load specifications detail that the open collector output can handle 24VDC at a maximum of 50mA, while the differential line driver output supports up to 0.1A. The device operates effectively with an input voltage of 24V DC, consuming 1.5W of power. Its input current is recorded at 60mA, while the output voltage mirrors the input at 24V DC, delivering a current of 0.5A per channel.
The isolation voltage is rated at 500V AC for design reliability, offering protection against electrical faults. Communication is established via the RS-485 protocol, facilitating integration into various systems. Mounting versatility allows the unit to be easily installed on DIN rails or via screw mounting, weighing roughly 150 grams.
The unit provides 8 separate I/O channels, promoting efficient use in complex setups. Both input and output response times are rapid at 1 millisecond, enhancing the system's performance. To ensure accuracy, the FRA7AL guarantees repeated positioning with an accuracy of ±1.5° at the motor shaft end. This combination of features makes the Mitsubishi FRA7AL integrated well into automation environments, requiring reliable precision and efficiency.
