IS220PTCCH1A Input

IS220PTCCH1A Input

IS220PTCCH1A is a thermocouple input manufactured by General Electric for the Mark VI/Mark VIe system. These systems are part of the Speedtronic system later developed and released by General Electric for the management and control of gas, hydraulic, and steam industrial turbine systems. This component is equipped with a BPPx processor board and an acquisition board for thermocouple input function. IS220PTCCH1A can be used for simplex, duplex and the third mock examination redundancy applications.

Operation of PDIA Discrete Input Module
Each Mark VIe Ethernet I/O pack or module shares a processing board. It has the following content:
A fast processor with RAM and flash memory is the top priority.
Two completely independent 10/100 Ethernet port plugs
Hardware reset and watchdog timer circuit
Internal temperature sensor
LED indicating status
Ability to read IDs and electronic identifiers on other boards
Input power connector with current limiter and slow start function
Local power supply, which also includes monitoring and sorting
The IS220PDIAH1A I/O package or module specific acquisition board is connected to the processor board. When input power is applied, the soft start circuit gradually increases the available voltage on the processor board. The processor is reset and turned off, and the local power is turned on in order. After completing the self check routine, the processor loads application code from flash memory specific to the I/O package or module type. To verify whether the application code, collection board, and terminal board are correctly matched, the application code reads the board ID information. When the match is good, the processor will attempt to initiate an Ethernet connection by requesting a network address.
The address request uses industry standard Dynamic Host Configuration Protocol (DHCP) and unique identifiers of the terminal board. After the Ethernet is started, the CPU runs the application program, programs the onboard logic, and allows the collection board to start working. The entire circuit required to enable I/O packets to run from one or two Ethernet inputs is included in the processor application code. When using two Ethernet inputs, both network paths are always active. I/O package or module operations will not be affected by any network failure, and a functioning network connection will display a fault. Compared to traditional hot backup systems, this configuration only uses the second port when the primary port fails, which has higher fault tolerance.

IS200VCRCH1B is a contact input/relay output board manufactured by General Electric
Part of the Mark VI series used in gas turbine control systems. The contact input/relay output board accepts 48 discrete inputs and manages 24 relay outputs from a total of four terminal boards through its accompanying sub boards. The dual width VCCC module is installed in the VME I/O rack. Two sets of J3/J4 connections are provided in this rack for connecting to TBCI and TRLY terminal boards.
Contact input
The contact input terminal board (TBCI) is used for the first 24 dry contact inputs; Input 25-48 requires a second terminal block. The contact provides DC power. The terminal board is connected to the VME rack equipped with a VCCC processor board through a cable with a molded plug. For monitoring inputs of key turbine variables, high-speed scanning and recording of 1 millisecond per second can be performed. The Event Sequence (SOE) recorder can report contact tremors and pulse widths as low as 6 ms, as well as all contact opening and closing with a time resolution of 1 ms.
Relay output
TRLYH1B stores 12 plug-in magnetic relays. Jumpers can be used to set the first 6 relay circuits, driving external solenoids or dry C-type contact outputs. For on-site solenoid valve power supply, standard 125 V DC or 115 V AC power supply and optional 24 V DC power supply can be provided, with separate jumper optional fuses and onboard suppression. The following five relays (7-11) have independent C-type contacts that are not energized. Output 12 uses isolated C-type contacts for special applications such as ignition transformers.
