IS200ESYSH1A GE EX2100e, System I/O TMR Card

Description:

The IS200ESYSH1A model is part of the EX2100e Excitation Controller Series of Models produced by General Electric Industrial Systems. The functional acronym for this model is ESYS which stands for EX2100e System Interface Board for Customer I/O.

The EX2100e Regulator system is available in several configurations to provide control flexibility for Thyristor and Regulator systems. For small Regulator systems, two pulse-width modulated (PWM) power converter modules use Insulated Gate Bipolar Transistors (IGBT) to provide up to 35 A or 120 A nominal output. These systems can support the following applications:
• Saturable Current Transformers / Power Potential Transformers (SCT/PPT) regulator
• Brushless exciter regulator
• Direct current (dc) rotating exciter regulator

In the SCT/PPT regulator and dc rotating exciter regulator applications, the EX2100e Regulator system can de-sensitize the effect of the exciter time constant. It incorporates direct measurement of the generator field voltage and field current to enhance speed of response to system transients.

The architecture is a single control with a single Power Control Module (PCM) or dual control with dual PCM, including a customer interface sub-system, optional diagnostic local operator interface (touchscreen), optional control operator interface (COI) remote touchscreen interface, control power input module, and PCM. The PCM consists of a bridge interface sub-system, power bridge, optional ac and dc filter networks, and alternating current (ac) and/or dc isolation devices. For expanded input and output (I/O) capability, either VersaMax® or Mark* VIe control IONet I/O modules may be added.

The EX2100e Regulator system supports Ethernet local area network (LAN) communication to the following:
• Turbine controls and ICS, HMI, Proficy*-based Historian, Programming Interface (PI-based) Historian, Onsite Monitoring System (OSM), and COI
• Extended I/O modules using the Ethernet Global Data (EGD) protocol
• Customer DCS through Ethernet or Modbus Ethernet remote terminal unit (RTU)
• ToolboxST* application
• GE Onsite Support* for monitoring and diagnostics

The IS200ESYSH1A is designed to handle all necessary input and output interfacing. This includes PT and CT inputs, general-purpose and trip relay outputs, analog inputs and outputs, as well as digital control inputs. These interfaces occur through terminal boards mounted on the ESYS board via their terminal strips, which offer terminal connections. These daughter boards are typically HSSL or HSLA boards. 

The IS200ESYSH1A board itself has isolation transformers that take care of current measurements and generator voltage. The board can take care of two three-phase PT voltage inputs and two CT inputs. It can also manage analog inputs (4 to 20 mA or +/- 10 V.). Additionally, the board supports excitation contact I/Os and has two trip relay outputs that will drive a customer lockout device.

On page eight there is an EX2100e Regulator Dual Control System Block Diagram that details what the External IS200ESYSH1A model is connected to how and it functions.

Frequently Asked Questions:

1.How does the l/O module contribute to system reliability?
Itensures real time signal processing, fault detection, and redundancy support for critical operations, reducing the risk of failures in the excitation system.

2.What are the typical voltage and current ratings for digital I/O channels?
Common digital input voltage levels are 24 DC or 48V DC, and digitaloutput relays can hande up to 25oVAC or 30V DC with current ratings of 2A-5A.
