GE IS200EMCSG1AAB

Technical Parameters

Selector Switch: 3-position ("Auto–Manual–Offset") rotary encoder, detented

Analog Outputs:

0–10 V DC analog drive for manual field-voltage control

4–20 mA loop output option via onboard jumper

Digital Inputs/Outputs:

Two discrete inputs for external interlocks (Enable, Inhibit)

Two discrete outputs for mode-status indication (Auto, Manual)

Resolution & Accuracy:

Voltage: 12-bit DAC, ± 0.2 % full scale

Current: 16-bit loop converter, ± 0.1 % full scale

Connectorry:

Front-panel: sealed rotary switch assembly with mounting bezel

Backplane: dual 50-pin edge connectors to I/O-pack carrier

Environmental:

Operating Temp: –20 °C to +60 °C

Storage Temp: –40 °C to +85 °C

Humidity: up to 95 % RH, non-condensing

These parameters apply to GE IS200EMCSG1AAB.

Product function

Mode Selection: Toggles excitation control between automatic governor output and manual operator input.

Manual Adjustment: Provides smooth, proportional field-voltage control via rotary knob, with fine-adjust "offset" position for trimming.

Status Feedback: Drives discrete signals to the controller indicating current selection, and presents "Auto-OK"/"Manual-OK" health bits.

Seamless Transfer: Implements make-before-break logic to avoid transients when switching modes.

GE IS200EMCSG1AAB performs these functions.

Core supporting modules

Exciter Controller: EX2100e or Mark VIe CPU handling governor and field-voltage commands.

Analog Drive Pack: IS200DAMCG1A for high-precision DAC outputs if loop-powered current is required.

Digital I/O Packs: IS200TICIH2A for capturing external interlock signals; IS400TRLYS1B for driving status lamps.

GE IS200EMCSG1AAB integrates with these modules.

Extension components

Front-Panel Bezel Kits: Rain-tight gasketed panels with selector legend overlays.

Knob Assemblies: Spare rotary encoder modules with detents and tactile feedback.

Terminal Blocks: Pluggable screw-clamp blocks for I/O wiring, keyed by function.

DIN-Rail Adapter: Optional guide clips for mounting in non-VME enclosures.

All extensions support GE IS200EMCSG1AAB.

Software support

Configuration: Mode-mapping and analog-range settings defined via GE ToolboxST™ templates.

Diagnostics:

"Switch-OK" health and "Position-Mismatch" alarms reported in HMI and OPC-DA tags.

Automatic self-test on power-up with failure flags logged in controller diagnostics.

Firmware: Passive hardware; no onboard firmware. Mode logic and alarms managed in the governor application.

Documentation: Detailed in the EX2100e Manual and Mark VIe I/O Installation Guide under "Manual Control Selector Module."
