AJ65SBTB1-16D Mitsubishi Universal model Redundant Power Supply Module
AJ65SBTB1-16D Description
The Mitsubishi AJ65SBTB1-16D is a 16-point digital output module designed for the MELSEC-Q series PLC. It functions as a remote terminal block within Mitsubishi's CC-Link network system. This module acts as an interface, receiving output commands from the CC-Link master station (e.g., a Q-series PLC with a master module) and switching the state of its 16 output points to control field devices like relays, solenoids, indicator lamps, and small motors. Its compact, terminal-block style design allows for distributed I/O installation close to the machinery, significantly reducing wiring costs and improving system flexibility.
AJ65SBTB1-16D Features
•CC-Link Compliance: Fully compatible with the CC-Link open field network, enabling high-speed, reliable communication with the network master station.
•16 Output Channels: Provides 16 isolated digital output points for controlling various actuators in an automation system.
•Sinking Output Type: The outputs are of the sinking (current-sinking) type, meaning the common terminal is connected to the positive voltage, and the module sinks current to activate the load.
•Compact and Space-Saving: The slim, block-type design saves control panel space and allows for installation near sensors and actuators.
•Easy Wiring: Uses a simple screw terminal block for straightforward and secure wiring connections.
•Diagnostic LEDs: Equipped with LEDs for power status (PWR), run status (RUN), and communication status (COM), providing quick visual diagnostics for easier maintenance and troubleshooting.
•Reliable Performance: Designed for high noise immunity and stable performance in industrial environments.
AJ65SBTB1-16D Material and Application
•Primary Material: The module housing is typically made from robust, flame-retardant plastic (e.g., PBT/PC), suitable for industrial use. The terminals are metal (e.g., plated copper alloy).
•Usage/Application: This module is used to extend the digital output capabilities of a MELSEC-Q series PLC system via a CC-Link network. It is ideal for applications requiring distributed control, such as:
•Conveyor systems
•Packaging machinery
•Automated assembly lines
•Material handling systems
•Any application where centralized control with distributed I/O is beneficial.
