Product Description  

The RTD Input Modules allow RTD temperature sensors to be directly connected to the PLC 

without external signal processing (transducers, transmitters, etc.).  All analog and digital processing of 

the RTD signal is performed on the module, and temperature values in 0.5°C or 0.5°F increments 

(RTD600) or 0.125°C, 0.1°C or 0.1°F (RTD601) increments are written to the 90-30 %AI input table.  All 

modules feature six channels, and support PT-90 (MIL-7990); PT-100E, PT-100C, and PT-100Z; Ni-120, 

Cu-10, Cu-50, Cu-53, Cu-100, Pt-1000, TD5R and Linear Resistance. 

ABOUT PROGRAMMING EXAMPLES

Any example programs and program segments in this manual or provided on accompanying diskettes are

included solely for illustrative purposes.  Due to the many variables and requirements associated with any

particular installation, Horner APG cannot assume responsibility or liability for actual use based on the

examples and diagrams.  It is the sole responsibility of the system designer utilizing the Resistance

Temperature Device Input module to appropriately design the end system, to appropriately integrate the

Resistance Temperature Device Input module and to make safety provisions for the end equipment as is

usual and customary in industrial applications as defined in any codes or standards which apply.

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

• ExtendedI/O modules using the Ethernet Global Data (EGD) protocol

• CustomerDCSthrough Ethernet or Modbus Ethernet remote terminal unit (RTU)

• ToolboxST application

• GE OnsiteSupport for monitoring and diagnostics

ControlHardware

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

• Directcurrent (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.

Overview

The EX2100e Excitation Control Regulator system is GE’s most recent state-of-the-art

control system for steam, gas, or hydro generators for both new and retrofit units. Control

hardware and software design is closely coordinated between GE’s system and controls

engineering to ensure delivery of a true system solution. Integration is seamless between

Excitation Control systems, Turbine Control systems, Static Starter Control systems,

Integrated Control Systems (ICS), and the Human-machine Interface (HMI). For

stand-alone retrofit applications, integration with customer distributed control systems

(DCS) through serial or Modbus ® Ethernet is supported. This document specifically

addresses applications for the 35 A and 120 A (nominal) series of EX2100e Control

Regulator systems.

Derating for Low Air Pressure

 The cooling capability of air is decreased at low air pressure.

 For altitudes above 2000 m, please contact GE .

 Below 1000 m altitude no de-rating is necessary but above 1000 m the ambient 

 temperature or the maximum output current should be decreased.

 Decrease the output by 1% per 100 m altitude above 1000 m or reduce the max.

 ambient temperature by 1 degree per 200 m

Derating for Ambient Temperature

 The ambient temperature measured over 24 hours should be at least 5 °C lower than the max. ambient

temperature.

 If the frequency converter is operated at high ambient temperature, the continuous output current

should be decreased.

 The frequency converter has been designed for operation at max 50 °C ambient temperature

 with one motor size smaller than nominal. Continuous operation

 at full load at 50 °C ambient temperature will reduce the lifetime of the frequency converter.
