GE IS220PDIOH1B Discrete I/O pack
Description：
IS220PDIOH1B is part of GE Mark VI series module. It is a discrete I/O turbine control module, which can be used in hazardous locations. Terminal boards can be used with are ISx0yTDBSH2A, ISx0yTDBSH8A, ISx0yTDBTH2A, or ISx0yTDBTH8A
The Discrete InputOutput (PDIO) pack provides the electrical interface between oneor two I/O Ethernet networks and a discrete input/output terminal board. The packcontains a processor board common to all Mark* Vle distributed I/O packs and anacquisition board specific to the discrete input output function. The pack accepts upto 24 contact inputs. controls up to 12 relay outputs, and receives terminal boardspecific feedback signals. The associated terminal board determines voltage capabilityof PDIO. System input to the pack is through dual RJ45 Ethernet connectors and athree-pin power input. Discrete signal input/output is through a DC-62 connector thatconnects directly with the associated terminal board connector. Visual diagnostics areprovided through indicator LEDs.
PDIO is the functional equivalent of a PDIA and PDOA I/O pack combined into asingle assembly. For siplex applications, it goes on a TDBS terminal board that isthe equivalent of a SRLY relay terminal board combined with a STCI contact inputterminal board. For TMR applications. it goes on a TDBT terminal board that. withthe WROB option provides the equivalent of a terminal board combined with a TBCIcontact input terminal board.
