The 1769-L27ERM-QBFC1B is a module in Rockwell Automation’s Allen-Bradley CompactLogix controller family. Designed for critical turbine controls that require high reliability, this module is part of the Woodward 5009 fault-tolerant controller.

The features of this module are as follows:

High reliability: The 5009 fault-tolerant controller is designed in triple-redundant form, including CPU and I/O (TMR), to meet the stringent reliability requirements of the industrial turbine market.

Configuration Flexibility: The module can be configured for turbine applications such as pure condensing, back pressure or single pump/recharge to suit different turbine control requirements.

Communication and integration: The 5009 controller can work independently or in combination with the plant’s DCS (Distributed control system), providing a flexible system integration solution.

Closed-loop control function: The module has closed-loop control function and can accept editor feedback or pulse input feedback to achieve accurate control.

Voltage adaptability: The module can optionally operate under 1/2 bus voltage conditions, which enhances the low voltage inertia crossing capability.

Pre-charging unit: Built-in pre-charging unit, suitable for common DC bus or DC bus sharing scheme, improve the efficiency and stability of the system.

Synchronization and speed adjustment: The module has a synchronous input slope and output frequency up to 500Hz, while supporting the adjustment of the speed ratio via communication commands.

Other features: Also include swing frequency function, P-Jump, slip calculation and display function, these features make the module excellent performance in induction motor control.
