Product Description

The IS220YTURS1A module is a key component in GE’s Mark VIeS Series, designed for turbine protection and control. It interfaces with IONets and a primary protection terminal board, ensuring seamless communication and control within the turbine system. The module supports four-speed sensor inputs, bus and generator voltage inputs, shaft voltage and current signals, eight flame sensors, and outputs to the main breaker. It is compatible with TTUR and TRPA terminal boards, offering flexibility in system configuration.

The module is equipped with safety-certified protection features, including:

• Speed Interface: Supports up to four passive, magnetic speed inputs with a frequency range of 2 to 20,000 Hz.
• Flame Detection: Detects voltage pulses above 2.5 V, generating a logic high. The pulse rate is measured over a configurable time interval.
• ETD TRPx Relays: Interfaces with electrical trip devices (ETD) for enhanced safety.

The YTURS1A is designed with a fail-safe mechanism, ensuring that the system maintains required outputs even in the event of a hardware fault or communication loss.
