Redundant Power Supply Module Mitsubishi Universal model AJ55TB2-16R
AJ55TB2-16RDescription
The AJ55TB2-16R is a high-performance remote relay output module designed for industrial fieldbus distributed control systems. It acts as a network slave station, receiving control commands from the main controller via fieldbus communication, and provides 16-channel mechanical relay contact outputs to drive various industrial actuators, solenoid valves, contactors and indicator devices. Featuring compact structure, built-in isolation circuit and reliable relay switch performance, it is widely applied in decentralized automation scenarios requiring dry contact signal output.
Dry Contact Relay Output:Form A normally open contact output, suitable for AC and DC mixed load circuits.
Built-in Optocoupler Isolation:Complete electrical isolation between internal communication circuit and external relay contacts to suppress interference.
Fieldbus Network Compatibility:Supports mainstream industrial fieldbus protocols, occupying few network stations to save address resources.
LED Status Indication:Front panel power, network communication and individual channel status LEDs for quick on-site diagnosis.
Industrial Grade Relay:Long mechanical and electrical service life, stable switching under rated load for long-term continuous operation.
Screw Terminal Wiring:Standard screw terminal block for firm wiring, anti-loosening and suitable for vibration environment.
DIN Rail Mounting:Standard DIN rail installation, easy to assemble, replace and expand in control cabinets.
Overvoltage & Surge Suppression:Built-in absorption circuit to protect relay contacts and rear-stage loads from voltage impact.
Wide Environmental Adaptability:Withstands temperature fluctuation, humidity and mechanical vibration in factory workshop conditions.
AJ55TB2-16R Materials & Applications
Materials
Housing:Flame-retardant high-strength engineering plastic with UL94 V-0 grade, good insulation and impact resistance.
Relay Unit:Industrial electromagnetic relay with alloy contacts, oxidation resistance and stable conduction performance.
Terminals:Nickel-plated brass screw terminals, corrosion resistant and reliable wire connection.
Internal Components:Optocoupler isolators, surge absorption elements, voltage regulation chips and filter circuits.
Indicators:Long-life high-brightness LED lamps for clear status display.
Typical Applications
Factory Automation:Control of solenoid valves, air cylinders, hydraulic valves, intermediate relays and signal lights.
Packaging Machinery:Actuator control, sealing and positioning switch signal output.
Material Handling:Conveyor system start-stop control, sorting mechanism and diverter action output.
Machine Tools:Cooling system, lubrication system and safety interlock loop control.
Water Treatment:Water pump, fan and electric valve switch control.
Textile & Printing Machinery:Action control of transmission mechanism and executive components.
Building Automation:Air conditioning fan, lighting and pipeline valve remote control.
General Industrial Control:Dry contact signal switching and interlock control of various automation equipment.
