Turbine Communication Special I/O Monitor Module IS220PTURH1B（IS230TNTRH1C）GE

Description

TheGE IS220PTURH1Bmodule is engineered to supportgas and steam turbine protectionthroughhigh-speed signal processinganddeterministic trip logic. It connects to terminal boards such as theIS200TRPAS1Aand works in tandem with theIS230TNTRH1C I/O packto manage critical input/output signals essential forsafe turbine operation. Moreover, this module is part ofGE’s Speedtronic control architecture, widely used inpower generation facilitiesworldwide. It supportsredundant configurations, ensuringhigh availability and fault toleranceinsafety-critical environments. In addition, itsconformal coatingandrobust designallow it to operate reliably under harsh industrial conditions. The IS220PTURH1B isDIN rail-mountedand featuresmodular connectivity, making it easy to install, maintain, and upgrade. Its integration withMark VI and Mark VIe systemsensuresseamless communicationandfast response timesduring turbine trip events.
