GE IS220PTURHS1A | Mk VIe gas turbine control device

Description

Product type: GE IS220PTURHS1A I/O component, which is part of the GE Speedtronic Mk VIe gas turbine control system.
Functional characteristics: It is a one-time trip component of the steam turbine, with an interface with four passive magnetic speed inputs. The circuit sensitivity can detect the speed of the 2RPM turning device to determine whether the turbine has dropped to zero speed. The intermediate speed signal on the unit is used for speed control and the main overspeed trip signal.
Hardware configuration: The processor board has two 10/100 Ethernet ports, flash and RAM, a read-only chip for recognition, an internal temperature sensor, and a reset circuit. The shell is black, with multiple LED indicator lights at the front and an unused infrared port (IR). Inside, there is a processor board, a turbine control specific board, and an analog acquisition auxiliary board.
Power supply and voltage parameters: The power supply voltage is 27.4-28.6V DC; TRPA voltage detection input is 16-140V DC; TRPA emergency stop input voltage is 18-140V DC; TRPA speed input voltage is -15-15V DC; The output voltage of the emergency stop power supply is 28V DC (open circuit voltage) and 17mA DC (short circuit current); The output voltage of TRPA contact is 24V DC.
Other features: Supports automatic reconfiguration, can automatically download I/O components from the controller, including base loads, boot loads, firmware, and parameters, etc., can be enabled or disabled through the Component Editor in the Toolbox ST application.
Appearance and size related: The weight is approximately 0.36kg, and it is a module for installing guide rails.
