Technical Specifications
Redundancy mode: hot standby, bumpless transfer. Synchronization link: dedicated serial. Switchover time: <50ms. Power supply: 24V DC. Power dissipation: 4W. Operating temperature range: -40°C to +70°C.
Functional Features
Bumpless controller switchover. Automatic data synchronization. Fault detection and switchover logic. Status indicators. Hot-swap capability.
Application Scenarios
It provides high-availability redundant control for critical engine generator sets, turbine drives and process systems requiring maximum uptime.
Performance Parameters
Switchover time: <50ms bumpless. Synchronization latency: <1ms. Operating temperature range: -40°C to +70°C.
Material Composition
Housing: flame-retardant plastic. PCB: FR-4. Connectors: gold-plated copper.
Structural Characteristics
MicroNet standard module, front panel status LEDs, redundancy link connector, rear backplane connector, DIN rail mounting.
Working Principle
It continuously synchronizes program and I/O data between redundant controllers. It detects primary controller faults and initiates bumpless switchover to the secondary controller, maintaining uninterrupted process control.
Installation Requirements
Install one module in each controller chassis. Connect redundancy link cable. Configure redundancy parameters. Test switchover at commissioning.
Usage Notes
Both controllers require identical programming. Test switchover periodically. Check status indicators.
