GE IS220PCLAH1A Core Analog I/O Module

GE IS220PCLAH1A Core Analog I/O Module

Functional Description

The IS220PCLAH1A Core Analog I/O for Aero-derivative gas turbines (PCLA) and associated Core Analog

(SCLS and SCLT) terminal boards provide a large portion of the analog signal I/O required to operate an

engine. PCLA and SCLT provide thermocouple inputs, RTD inputs, voltage inputs, and 4-20 mA current loop

inputs and outputs. PCLA can be applied in simplex controller simplex I/O, dual controller simplex I/O, dual

controller TMR I/O and TMR controller TMR I/O control systems. A single SCLT terminal board fans signal

inputs to one or three connected PCLA(s).

PCLA provides the electrical interface between one or two Ethernet I/O networks and the terminal board. It

contains a processor board common to all Mark VIe distributed I/O. Input to the PCLA module is through

dual RJ-45 Ethernet connectors and a 28 Vdc power connector P1.

Field device I/O is connected through 72 Euro-style box terminals on the SCLS edge and is connected

through 48 Euro-style box terminals on the SCLT edge. Connection to SCLS is through 96-pin J3 and 48-pin

J4 connectors on SCLS. The connection between SCLS and SCLT is through one 68-pin cable on the J2

connector on SCLS, and the JR/JS/JT connector on SCLT.
