Woodward 505DR Dual Redundant Turbine Controller Communication

From:Woodward | author:Mr.Chen | Time :2025-09-04 | 4 view: | Share:

Communication

The 505DR can communicate directly with the plant DCS and/or operator control panel using Modbus TCP or OPC communications.

Serial communication is also supported using RS-232 or RS-485 and ASCII or RTU Modbus.

Control PIDs can perform process control or be used as limiters for speed/load dynamics,

pumping/discharge pressures, cascade, auxiliary, intake plenum, exhaust plenum, and rotor acceleration.

System Protection

- Integrated overspeed protection logic and test functions

- First open indication on 15 shutdown inputs

- External alarm indication on 15 inputs

- Stuck at critical speed band logic

- Bufferless transfer between control modes and during Syscon switchover

- Operation and configuration password security

Control specifications

Inputs

- Power Supply Low voltage models 18-32 VDC High voltage models 88-264 VAC and 90-150 VDC

- Speed: 2 passive MPUS or active proximity probes (0.5 - 32000 Hz)

- Discrete Inputs 19 configurable contact inputs (16 additional contact inputs can be added using LinkNet HT)

- Analogue Inputs 8 configurable 4-20 mA (16 inputs or 8 RTD inputs can be added using LinkNet HT)

Outputs

- Valve/actuator driver: 2 actuator outputs, 4-20 mA or 20-200 mA

- Discrete Outputs:

- 7 configurable relay outputs (16 discrete outputs can be added using the LinkNet HT module)

- Analogue Outputs 6 programmable 4-20 mA outputs (4 inputs can be added using the LinkNet HT module)

Communications

- Ethernet 3 ports (Modbus TCP or OPC)

- Serial 1 port (ASCII or RTU, RS-232 or RS-485)

- CAN: 4 ports, supports LinkNet HT, VariStroke, and power management devices
