The Mitsubishi QJ71PB93D module is a PROFIBUS-DP slave module designed to integrate into industrial automation systems. This module adheres to the EN50170 Volume 2 (Parts 1, 2, 3, 4, 8) specifications, confirming its suitability for various applications.
Users can set station numbers between 0 and 125. The module facilitates communication of 192 words in total, with up to 122 words allocated to I/O data. The transmission characteristics comply with EIA-RS485 standards and utilize shielded twisted pair cables (Type A) for connectivity.
For network configuration, the QJ71PB93D supports bus topology but can also operate in a tree structure when connecting additional repeaters. It employs a polling method for data link operations and uses Non-Return-to-Zero (NRZ) encoding for transmitting information.
The transmission speed ranges from 9.6 kbps to 12 Mbps, with varying maximum distances per segment based on the speed. At lower rates, distances can reach 1200 meters, while at higher speeds, distances drop to 100 meters.
Users may connect up to three repeaters, allowing a maximum of 32 modules per segment, including repeaters. The internal power consumption for this unit is rated at 0.44 A at 5V DC, and it has a compact mass of 0.11 kg.
