QJ71PB92V PROFIBUS-DP V1/V2 Master Module for MELSEC-Q | Mitsubishi

The Original New Mitsubishi QJ71PB92V is a PROFIBUS-DP master module for the MELSEC-Q series, designed to connect Q series programmable controllers to PROFIBUS-DP networks as a Class 1 DP-Master station. It supports the PROFIBUS-DPV1 and DPV2 advanced function sets, enabling acyclic slave communication, slave alarm acquisition, and slave station clock control, in addition to standard cyclic I/O data exchange. With support for up to 125 DP-Slaves, a maximum transmission rate of 12 Mbps, and up to 8,192 bytes of I/O data per module, the QJ71PB92V provides a high-capacity communication interface for integrating PROFIBUS-compatible devices into Mitsubishi automation systems.

Core Engineering Highlights:
PROFIBUS-DPV0 / DPV1 / DPV2 support | Class 1 DP-Master station | 9.6 kbps to 12 Mbps transmission speed | Up to 125 DP-Slaves per module | Max. 8,192 bytes I/O data (Max. 244 bytes per DP-Slave) | EIA-RS485 compliant | Shielded twisted pair cable | 0.57 A internal current consumption (5 V DC) | 27.4 × 98 × 90 mm | 0.13 kg
