MPC4 and MPC4SIL mechanical protection cards for the VM600 rack mounted mechanical monitoring system
The high quality, GE reliable interface (input/output) card. The I0C4T card supports four dynamic passes
Channel and 2 tachometer (speed) channels, all of which can be configured independently. I0C4
The T interface card is installed at the rear of the VM600 ABE04x rack, in the MPC4-card or MPC4S
IL card directly behind to form card pair.
trait
The input/output (interface) card for MPC4 or MPC4SIL cards supports 4 dynamic channels and 2 tachometer channels
● Differential signal input and sensor power output for each dynamic channel and sea tachometer channel
● Differential buffering (raw) sensor output for each dynamic channel
● The DC output of each dynamic channel can be configured as a current-based signal (4 to 20 mA) or a paper-based signal (0 to 10 V)
● Four configurable relays, each with two contacts, and alarm reset (AR), hazard bypass (DB), and trip multiplier (TM) control inputs
Features of the VM600 IOC4T include:
Turbines suitable for wind farms, typically three-bladed, have low torque fluctuations that contribute to good reliability. The blades are usually white, easy for aircraft to see during the day, and are between 20 and 80 meters in length. The size and height of turbines are increasing year by year, such as offshore wind turbines up to 8 megawatts with blades up to 80 meters in length.
The IOC4T card supports 4 dynamic channels and 2 tachometer (speed) channels, all of which can be configured independently. This modular design allows users to configure according to actual needs, with high flexibility.
The IOC4T interface card is installed at the rear of the VM600 ABE04x rack to form a card pair. This design makes the installation and use of the module more convenient, and also facilitates the maintenance and upgrade of the system.
The IOC4T card also has advantages when the turbine is integrated into a building. It does not need to be pointed into the wind to be effective, which is an advantage where the wind direction is highly variable. At the same time, the generator and gearbox can be placed near the ground, using direct drive from the rotor assembly to the ground gearbox, improving maintenance accessibility.
Overall, the VM600 IOC4T is a highly reliable, flexible configuration and suitable input/output module for turbines on wind farms.
