GE IS220PTURH1B Mark VI Series Turbine I/O Module
Description:
IS220PTURH1B is GEMark VI Series I/O pack. The Primary Turbine Protection (PTUR) pack provides the electrical interfacebetween one or two l/O Ethernet networks and a turbine control terminal boardThe pack contains a processor board common to all Mark* Vle distributed I/Opacks, a board specific to the turbine control function, and an analog acquisitiondaughterboard. The pack plugs into the TTURHlC terminal board and handlesfour speed sensor inputs, bus and generator voltage inputs, shaft voltage andcurrent signals, eight flame sensors, and outputs to the main breaker. Input to thepack is through dual RJ45 Ethernet connectors and a three-pin power input.Output is through a DC-62 pin connector that connects directly with theassociated terminal board connector. Visual diagnostics are provided throughindicator LEDs, and local diagnostic serial communications are through aninfrared port.
As an alterative to TTURHlC, three PTUR packs may be plugged directly intoa TRPAHlA terminal board. This arrangement handles four speed inputs perPTUR, or alternately fans the first four inputs into all three PTURs. Two solidstate primary trip relays are provided by TRPA. This arrangement does notsupport bus and generator voltage inputs, shaft voltage or current signals, flamesensors, or main breaker output. Refer to TRPAHlA documentation foradditional details.
