GE 12CEH52A1DL

Product Name:​ GE CEH Series Single-Phase Relay (Loss-of-Excitation Relay)
Product Introduction:​ Based on the GE CEH52A platform, this device belongs to GE's family of single-phase protective relays. The CEH-type functions as a generator loss-of-excitation (LOE) protection relay, designed to detect the disappearance of synchronous machine excitation and initiate tripping action.

GE IS220YTCCS1A

Product Name:​ Mark VIe YTCC Millisecond Analog Module (Thermocouple Input Pack)
Product Introduction:​ This is a highly specialized simplex I/O pack developed for the GE Mark VIe platform. While some sources describe it as monitoring shaft voltage/current for turbine health diagnostics, the predominant configuration is a high-precision thermocouple input module that interfaces specialized analog turbine sensors with the IONet control fabric.

GE DS200NATOG2A

Product Name:​ Voltage Feedback Scaling Board (NATO), G2 Group Variant
Product Introduction:​ This board is a precision voltage attenuation hub designed for LS2100 Static Starter and Mark V Speedtronic control systems. It attenuates high AC phase voltages and DC bus voltages from SCR bridges, converting 1200–6900 V inputs to scaled low-voltage signals for control system processing.

GE DS3800NSCD1B1C

Product Name:​ Mark VIe Dual-Channel Serial Communication Termination Board (Ruggedized)
Product Introduction:​ This is a ruggedized, dual-channel serial communication termination board designed for harsh industrial environments. The "1B" revision upgrades surge suppression to 1.5kW TVS diodes, while the "1C" revision adds reinforced through-hole terminal anchoring and a high-Tg PCB for extended temperature operation.

GE IS200EDFFH2A

Product Name:​ DC Fanned Feedback Board (EX2100e Excitation Control System)
Product Introduction:​ This board is a critical I/O terminal board within GE's EX2100e excitation platform. The "H2" group variation denotes a dual-system configuration, providing enhanced redundancy and reliability for field current and voltage feedback in exciter control applications.

GE 137D6723G1

Product Name:​ GE 137D6723G1 Multifunction Overcurrent Protection Relay
Product Introduction:​ The GE 137D6723G1 is a multifunction digital overcurrent protection relay. It integrates 50/51 overcurrent protection, 50G/51G residual overcurrent protection, 27 over/undervoltage protection, and 81O/81U over/underfrequency protection in a single 1/4 DIN panel-mount device. It is used for the protection of medium/high-voltage distribution systems and industrial motors.

GE DS3800HUMA1B1C

Product Name:​ GE DS3800 HUMA Universal Memory / Data-Processing Board (Mark IV Speedtronic)
Product Introduction:​ The GE DS3800HUMA1B1C is a memory / data-processing board (auxiliary microprocessor unit) for GE's Mark IV Speedtronic turbine control system and EX2000 exciter control racks. It hosts a local microprocessor and battery-free memory, bridging high-speed data between the CPU and remote I/O cards while isolating 5 V logic from 480 V field circuits.

GE DS2020FEANRX050A

Product Name:​ GE Mark VIe Field Excitation & Analogue I/O Board (50 A)
Product Introduction:​ The DS2020FEANRX050A is a field excitation board in GE's Mark VIe control series (GE Energy / GE Vernova). It integrates 50 A excitation control with redundant firing channels and combined analogue I/O, providing comprehensive excitation control for critical generators where loss of excitation is unacceptable.

GE 531X132APGACG1

Product Name:​ GE 531X Series Motor Field Control & Power Supply Board
Product Introduction:​ The GE 531X132APGACG1 is a motor field control and power supply board in GE's 531X replacement board series, developed for GE drive and exciter systems (including the GE EX2000 excitation system). It provides the necessary power to the drive and powers the motor field (excitation) circuit. The "G3" revision of this board has all MOVs (metal oxide varistors) for the AC line mounted externally rather than on the board.
