Product Description
Redundant Power Supply Module Mitsubishi Universal model AJ55TB2-16R
AJ55TB2-16R Description
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.
AJ55TB2-16R Key Features
- 16 Independent Relay Output Channels:16 isolated mechanical relay points for flexible multi-path load control.
- 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.
