The Mitsubishi AJ65BTD62D is a remote high-speed counter unit capable of managing input signals from both 1-phase and 2-phase systems. Designed for efficiency, it operates on two channels and supports signal levels compliant with the EIA Standard RS-422-A, utilizing differential line driver levels like the AM26LS31.
When working with 1-phase inputs, this unit reaches impressive maximum counting speeds of 400k pulses per second, with a lower threshold of 10k pulses per second. For 2-phase inputs, the maximum counting speed is 300k pulses per second, dropping to a minimum of 7k pulses per second. Further enhancing its capability, the AJ65BTD62D boasts a counting range based on a 24-bit binary format, allowing for counts from 0 up to 16,777,215.
The unit is sensitive to pulse width, requiring a minimum high pulse width of just 2.5 microseconds and a minimum low pulse width of 100 microseconds for 1-phase inputs. For 2-phase inputs, these values shift slightly to a minimum high pulse width of 3.3 microseconds and a low pulse width of 142 microseconds, supporting effective counting performance.
Input response times are optimized for quick action, with an OFF to ON response time of 0.5 milliseconds or less, and an ON to OFF response time of 3 milliseconds or less. The external input configuration, meant for preset or function-start applications, accepts voltage inputs of 5, 12, or 24 V DC with a current range of 2 to 5 mA.
For output functionalities, this counter unit is equipped with a coincidence output rated at 2 A per common, with output response times of 0.1 milliseconds or less, facilitating rapid data transmission. Classified as a remote device station (Version 1), the AJ65BTD62D occupies 4 stations within its designated configuration. Ideal for high-performance applications, this counter unit simplifies complex measurement tasks in various environments.
