AJ65BT-64DAV Mitsubishi Universal model Redundant Power Supply Module
AJ65BT-64DAV Description
The MITSUBISHI AJ65BT-64DAV is a 4-channel digital-to-analog (D/A) voltage output module designed for the MELSEC CC-Link open field network system. As a remote device station, it converts digital control signals from the PLC main station into precise analog voltage signals for controlling various industrial actuators. This module operates on the CC-Link Ver.1 protocol, occupying 2 stations on the network, and features a high-accuracy 12-bit effective resolution (16-bit encoded binary) for stable and reliable analog output. It is engineered for distributed I/O systems, enabling remote signal conversion and control across long distances in industrial automation environments. Note: This product was discontinued in September 2021, with successor models being AJ65SBT2B-64DA and AJ65SBT-62DA.
