PRODUCT INFORMATION
Product Overview
The General Electric IS220YTURS1A is a Turbine Input/Output Pack designed for Mark VI and Mark VIe control systems. This removable assembly carries the functional acronym YTUR and mounts directly to compatible turbine terminal boards. It supports nominal 28.0 V dc power supply inputs with an allowable range between 27.4 and 28.6 V dc. The hardware operates across an ambient temperature range of -30 to 65 degrees Celsius.
The pack interfaces with Mark VIeS safety systems through dedicated box connectors on compatible baseboards. Compatible terminal boards include the TTURS1C primary turbine protection board and TRPAS1A speed input boards. It also connects to TRPAS2A flame input boards, TRPGS1B trip relay output boards, and TRPGS2B emergency stop boards. This unit features an S-style conformal PCB coating and represents the first functional revision A of the design.
