About the IS200TRLYH1C
This IS200TRLYH1C Relay Output Terminal Board printed circuit board product offering, as should have been indicated above, was originally designed and manufactured specifically for insertion in General Electric's Mark VI Turbine Control System Series. The Mark VI Series that this IS200TRLYH1C Relay Output Terminal Board device belongs to is considered a self-explainable GE Mark product series based off of its full extended product series title, as its specifically exists with a range of intended functional product applications in the control systems and management systems of GE-compatible gas, steam, and even wind turbine automated drives. This must be defined as quite the significant functionality-minded upgrade upon the prior-released Mark V Turbine Control System Series, as the Mark V Series' possible application range was limited to gas and steam-based functional applications alone. This IS200TRLYH1C Relay Output Terminal Board product's Mark VI Series has to be separately valued for its status as one of the final-released GE Mark product series to exhibit the Speedtronic control system technology across a range of offerings.
Hardware Tips and Specifications
The IS200TRLYH1C is a Relay Output terminal board with Contact Sensing. This IS200TRLYH1C Relay Output Terminal Board is something of a highly-customizable style of Mark VI Turbine Control System Series printed circuit board product offering, given the fact that its normal style of Mark VI Series assembly is interrupted in several locations by a set of manually-moveable hardware jumpers; each accompanied by their own J-starting descriptive factory-printed nomenclature labels. This IS200TRLYH1C Relay Output Terminal Board device is actually not the originally-developed device of its specific Mark VI Turbine Control System Series functional role; that would have to be considered the IS200TRLYH1 parent Relay Output Terminal Board notable not utilizing this IS200TRLYH1C Relay Output Terminal Board device's sole C-rated functional product revision. The board has twelve plug-in magnetic relays, which fall into three distinct categories:
- Relays one through six are Form-C contact outputs. These drive external solenoids
- Relays seven through eleven are also Form-C contacts. However, these are unpowered.
- Relay twelve is an isolated Form-C contact with a non-fused power supply. This relay is used for ignition transformers.
The IS200TRLYH1C is built with four female cable connectors. These connectors are labeled JA1/JR1/JS1/JT1. Connectors are used to connect to the VCCC or VCRC board, which are also known as Contact Input/Relay Output Boards. When the TRLY model is used with the VCCC board, two are required to come up with a total of 24 relays. There are four female plug connectors on the board for the connection of solenoid power. The board has twelve fuses placed on the board in two lines of six. The board also has MOVs (metal oxide varistors) to aid with surge suppression. The IS200TRLYH1C is notched in two corners. The board has several factory-made drill marks located at several locations within the body of the board. Other components on the board surface include resistors, diodes, and jumper switches. The TRLY model can be used in two systems, Triple Modular Redundant (TMR) or Simplex. When the model is being used in a Simplex system the cable will carry all of the associated control signals, as well as monitor feedback voltages between the TRLY model and the VCCC board through the JA1 connection. For more information on the operation of the VCCC and TRLY models, refer to the attached manual.
