AJ55TB32-8DR Redundant Power Supply Module Mitsubishi Universal model
AJ55TB32-8DR Description
The Mitsubishi AJ55TB32-8DR is a terminal block type digital input module belonging to the MELSEC-A series of programmable logic controllers (PLCs). This module is designed to interface between the PLC CPU and field devices such as switches, sensors, and push buttons. Its key feature is the 8-point "relay output" functionality integrated via the terminal block, allowing it to directly drive small loads like indicator lamps, relays, or small solenoids without requiring a separate output module. This integrated I/O design is cost-effective and saves space in control panels for specific applications.
AJ55TB32-8DR Features
•Integrated I/O Solution: Combines 32 digital input points and 8 relay output points in a single module, simplifying wiring and reducing the number of modules required in a PLC rack.
•Terminal Block Connection: Features a removable screw terminal block for easy wiring and maintenance.
•Relay Output Contacts: The 8 output points use electromechanical relays, which provide physical isolation between the PLC and the load circuit. Relay contacts can switch both AC and DC loads.
•LED Status Indicators: Each input and output point has an LED to visually indicate its status (ON/OFF), aiding greatly in troubleshooting and diagnostics.
•Positive/Negative Common Logic: The input circuit can be wired with either a positive or negative common, offering flexibility for different sensor types (NPN/PNP sourcing/sinking).
•Internal Relays: Electromechanical components with metal contacts (e.g., silver alloy).
•Connectors: Phosphor bronze or other conductive alloys.
•Primary Applications:
•Small-scale automation systems
•Control panels for packaging machines
•Material handling systems
•Standalone machine control stations
•Applications requiring a compact mix of input sensing and output actuation.
