GE IS220PDIAH1A Discrete Input Module

IS220PDIAH1A Discrete Input Module

Functional Description

The Discrete Input (PDIA) pack provides the electrical interface between one or two I/O Ethernet networks and a

discrete input terminal board. The pack contains a processor board common to all Mark* VIe distributed I/O packs

and an acquisition board specific to the discrete input function. The pack accepts up to 24 contact inputs and

terminal board specific feedback signals, PDIA accepts three different voltage levels (with types TBCIH1, H2 and H3

terminal boards). Connections for the isolated discrete input board with voltage sensing (with type TICI board) are

available. System input to the pack is through dual RJ45 Ethernet connectors and a three-pin power input. Discrete

signal input is through a DC-37 pin connector that connects directly with the associated terminal board connector.

Visual diagnostics are provided through indicator LEDs.

Compatibility

IS220PDIAH1A is compatible with five types of discrete contact input terminal boards, including the TBCI boards,

TICI boards, STCI boards, but not the DIN-rail mounted DTCI board. The following table gives details of the

compatibility:

Control mode refers to the number of I/O packs used in a signal path:

• Simplex uses one I/O pack with one or two network connections.

• Dual uses two I/O packs with one or two network connections.

• TMR uses three I/O packs with one network connection on each pack.
