IS200EXHSG2A Exciter high-speed relay drive board

Part Number IS200EXHSG2A Manufacturer General Electric Country of Manufacture As Per GE Manufacturing Policy Series EX 2100e Function Module Availability In StockIS200EXHSG2A is an Exciter High-Speed Relay Driver Board manufactured by General Electric. It is part of EX2100 control systems. The Exciter High-Speed Relay Driver (EXHS) board is utilized in the EX2100 Excitation Control and provides drivers for the dc contactors (41) as well as pilot relays for field flashing and de-excitation. There are four EXHS board kinds based on the type of 41 dc contactor used. With the Exciter Backplane Board, these boards connect to three Exciter Main Input/Output Boards (EMIO, redundant control) or one EMIO board (simplex control). Features On the board are pilot relays for the flashing relays 53A and 53B, as well as pilot relays for the de-excitation relay KDEP. The Exciter De-Excitation Board (EDEX) de-excitation status signals are conditioned on EXHS and transmitted to EMIO. Crowbar status signals are conditioned on EXHS and delivered to EMIO from the De-Excitation Control Board. 

On EXHS, three contact inputs from 41, 53A, and 53B are powered by 70 V dc and their feedback is monitored. 

The connections are powered by the exciter power supply. 

The status signals generated are forwarded to the EMIO. Contact Inputs Contacts 53A, 53B, and 41 are brought into EXHS for EMIO monitoring. The contact input usage are similar in the simplex and redundant situations; however, for redundant control, the inputs are fanned to the M1, M2, and C controllers. Signals in simplex control are exclusively routed to the EMIO in the M1 controller. The three connections are wetted by EXHS's 70 V dc supply. Power is separated and provided to the contacts through resistors from connectors J12M1 and J12M2. The wetting voltage can range between 63 and 84 V dc. 

The resulting signal is distributed to M1, M2, and C, while the contact input monitoring circuit is located on EMIO. Application Data The close function contactor drivers are K41 (M1, M2, C), and the flashing pilot relays are K53A and K53B. The single de-excitation pilot relay is KDEP. J505, J508, and J515 are 25-pin connections for cables to the EMIO boards M1, M2, and C. 

They carry similar signals and have comparable wiring, with the exception that J505 is connected to M1, J508 is connected to M2, and J515 is connected to C. Nevertheless, J515 lacks de-excitation and crowbar signals. For auxiliary contact wetting, plugs J12M1 and J12M2 bring in 70 V dc from the M1 and M2 power supplies.CONNECTIONA TERMINAL BOARD

The board is an exciter high-speed relay driver. IS200EXHSG2A is the second group of variants of this board. This board is usually used in conjunction with high-speed contactor devices to support higher current applications. 

The motherboard is equipped with a heat sink assembly.This model is very limited, but it can be found in Axcontrol Inc. If this model is not available, AX Control will try its best to provide you with another model. 

Although there is little information about this particular model, the other models in the IS200EXHS series are the same, but they can be used for more redundant applications.
