GE IS220PDIAH1B Discrete Input Module
Description:
IS220PDIAH1B is belong to GE Mark VIe control system. IS220PDIAH1B is Discrete Input.
IS220PDIAH1B, the Discrete Input (PDlA) I/O pack provides the electrical interface between one or two I/O Ethernet networks and a discrete input terminal board. The PDIA contains a BPPx processor board and an acquisition board specific to the discrete input function. The l/O pack accepts up to 24 contact inputs and terminal board specific feedback signals. Three different wetting voltages are available, and isolated discrete input voltage sensing is also available when using a supported terminal board.
System input to the l/O pack is through dual RJ-45 Ethernet connectors and a three-pin power input. Discrete signal input is through a DC-37 pin connector that connectsdirectly with the associated terminal board connector, Visual diagnostics are providedthrough indicator LEDs.
Contact input terminal board types provide the following options:
· 24, 48, or 125 V dc wetting voltage options
· Simplex, dual, and TMR options
· Isolated input with ac wetting voltage options
The PDIA I/O pack includes one of the following compatible BPPx I/O processor boards:
·The PDIAHIA contains a BPPB processor board.
·The PDIAHIB contains a functionally compatible BPPC that is supported in the ControlST* software suite V04.04 and later.
The following is an explanation of redundancy options:
· Simplex uses one I/O pack with one or two network connections. 
· Dual uses two I/O packs with one network connection on each. 
· TMR uses three I/O packs with one network connection on each.
The PDIA I/O pack is compatible with the discrete contact input terminal boards listed in the following table. The DIN-rail mounted DTCI board is not compatible with the PDIA
