SKU: IS200EDCFG1A - RF Category:



Part Number: IS200EDCFG1A

Manufacturer: General Electric(GE)

Series: EX2100



  • The IS200EDCFG1A is a Exciter DC Feedback Board (EDCF) which is used in the EX2100 Excitation Control.
  • It monitors field current and voltage at the SCR bridge and communicates with the control panel’s EISB board via a high-speed fiber-optic link.
  • The field voltage is measured across the negative terminal of the bridge and the positive terminal of the current shunt.
  • At the SCR bridge, the field current is measured over a dc shunt. A low-level signal with a maximum value of 500 mV is generated and fed into a differential amplifier.
  • The amplifier’s output voltage varies from –5 V to +5 V, which is fed into a voltage-controlled oscillator.
  • IS200EDCFG1A receives power from a 24 V dc external source. Three voltage regulators come from this: +15 V dc, -15 V dc, and + 5 V dc. The ±15 V dc output voltages supply the PSOK green LED.
