Woodward 5466-253 High Density Combo I/O Module

Woodward 5466-253 High Density Combo I/O Module

5466 ‑ 253 is a High Density Combo I/O Module produced by Woodward in the United States. It is designed for TMR the third mock examination redundancy and 5009 fault-tolerant turbine control system.

5466‑253 integrates 4-way MPU magnetoelectric speed sensor input, 8-way analog input, 4-way 4 ‑ 20mA analog output, 2-way proportional actuator drive output, and communicates with TMR the third mock examination redundant CPU (CPU5200) through backplane bus to achieve turbine speed acquisition, steam pressure/lubricating oil pressure/valve position feedback and other analog signal acquisition, valve position command analog output, electro-hydraulic converter/servo valve proportional drive output; About 5ms high-speed update cycle, meeting the real-time requirements of turbine speed closed-loop control and valve proportional adjustment; 5466‑253 Under the integrated TMR the third mock examination redundancy architecture, three module independent computing, hardware voting, any fault does not affect the system output; It is a high-density core I/O unit in the MicroNet TMR steam turbine control system that integrates speed acquisition, analog I/O, and actuator drive. It is particularly suitable for controlling steam valves with proportional actuators. In the event of a fault, it can cause the loss of speed signals, abnormal analog control circuits, or uncontrolled valve drive outputs.

Product features

1.  High density combination I/O design, with a single module integrating 4 MPU speed inputs, 8 analog inputs, 4 analog outputs, and 2 proportional actuator outputs. One module can cover the speed acquisition, analog signal processing, and valve drive required for turbine control, greatly reducing the occupation of I/O slots in the chassis and suitable for compact TMR control systems.
2. 4-channel MPU magnetic electric speed sensor input, supporting two types of speed sensors: magnetic electric (MPU) and proximity probe. It can simultaneously collect signals such as turbine speed, zero speed, and steering detection, with a high-speed update cycle of about 5ms, meeting the real-time requirements of speed closed-loop control.
3. 8-channel analog input software can be configured with 0-5VDC or 4-20mA signal types, suitable for various transmitters and sensors in power plants; 4-channel 4-20mA analog output with a maximum load of 600 Ω, capable of driving valve position indicators, recorders, secondary instruments, etc; Two proportional actuator outputs directly drive actuators such as electro-hydraulic converters, servo valves, proportional electromagnets, etc.
4. TMR the third mock examination redundancy architecture, three module independent operation, hardware voting, when any module failure, the other two automatically take over, to ensure that the turbine control output is not interrupted; Optoelectronic isolation between channels, 500VDC to ground and 1000VDC to control common terminal isolation voltage, to suppress on-site electromagnetic interference.
5. Introduced in 1997, after long-term industrial field verification, the hardware is mature and stable; Certified by CE (EMC), CSA, UL, suitable for harsh industrial environments such as electricity and petrochemicals; Standard MicroNet chassis plug-in installation, supports hot swappable replacement.
