The IDP-801 Interactive Display Panel is a 7.5 inch/19 centimeter (measured

diagonally) color touchscreen interface that enables a user to monitor and

control a Basler Electric DECS-based excitation system.

IDP-801 monitoring and control features include DECS and excitation system

status, system control operations, and routine adjustments of the excitation

setpoint. The IDP-801 is compatible with DECS-250. DECS-250N, DECS-250E,

DECS-400. and DECS-450 Digital Excitation Control Systems.

DECS and synchronous machine system parameters are viewed and controlled

through interactive pages displayed by the IDP-801. Pages are organized according

to system functions. Navigation between pages and control of functions is achieved

by touching buttons located on the IDP-801 pages.

Communication between the IDP-801 and DECS is facilitated through the serial

communication port of the IDP-801 and the RS-485 port of the DECS.

One IDP-801 can monitor both the primary and secondary DECS in a dual DECS

application. The IDP-801 is equipped with an Ethernet communication port which

provides access to Modbus® registers for system monitoring and control of the DECS.

This capability enables integration of the IDP-801 into an existing Distributed Control

System (DCS).

Part number 9372900104 identifies the FIT

assembly. Part Number 9372900105 identifies the

FIT packaged for shipping and should be specified

when requesting a replacement or spare module.

Each FIT is supplied with a cable (Part number:

9372900021) for connecting the FIT (connector J1) to

the DECS.

For EMC-compliant installations, use FIT

9372900104 or 9372900105. and Cable 9372900021

FUNCTIONAL DESCRIPTION

Field sensing current is supplied to the module by a

user-supplied current shunt with an output rating of

50 mVdc or 100 mVdc. The field current sensing

input accepts up to 300% of the nominal current

range. The field current signal is converted into a

voltage signal from 2 to 9.5 Vdc and sent to the

DECS through connector J1.

Field sensing voltage is supplied directly from the

field to the module. The FIT accepts one of five field

voltage ranges: 63 Vdc, 125 Vdc, 250 Vdc, 375 Vdc,

or 625 Vdc. The field voltage sensing input accepts

up to 300% of the nominal voltage range. The field

voltage signal is low-pass filtered, converted into a

voltage signal from 0.9 to 9.1 Vdc, and sent to the

DECS through connector J1.

INTRODUCTION

The Field Isolation Transducer (FIT) is compatible

with DECS-400 and DECS-450 Digital Excitation

Control Systems, designated as DECS henceforth.

The FIT receives isolated operating power from the

DECS and supplies the DECS with isolated field

current and field voltage signals. An FIT is required

for each DECS unit used in an excitation system.

FITs are identified by four part numbers:

9372900100. 9372900101. 9372900104. and

9372900105.

DECS-400 Models

Part number 9372900100 identifies the FIT

assembly. Part number 9372900101 identifies the

FIT packaged for shipping and should be specified

when requesting a replacement or spare module.

Each FIT is supplied with a cable (Part number:

322900006) for connecting the FIT (connector J1) to

the DECS.

INTRODUCTION

The MOC2XXX series of motor operated controls consists of a motor-driven,

variable potentiometer and the limit switches required to provide remote

adjustment of resistance or voltage. MOC2XXX controls can be specified for

ac or dc operation with 24-, 32-, 48-, or 120-volt control power.

MODEL NUMBER DEFINITION

The model number for this series of MOCs consists of the prefix MOC2

followed by three digits. The first digit establishes the input control voltage.

The second and third digits establish the output control element characteristics.

Table 1 lists the available model numbers and the corresponding operating

characteristics. For example, MOC2305 has a 32 Vdc control input and a 500

ohm, 2 watt potentiometer.The MOC2 Motor Operated Potentiometer is a

motor-driven control device

designed to provide remote adjustment of resistance or voltage in power

system and control applications.

The MOC series combines a variable potentiometer with integrated limit

switches, enabling precise remote control while ensuring dependable

operation. Available in configurations supporting AC or DC operation with

24 V, 32 V, 48 V, or 120 V control power, the MOC2 offers flexibility for a

wide range of installation requirements.

Ideal for generator control, excitation systems, and industrial power
