GE IS220PSVOH1A PSVO Servo Control Module

Refurbishing IS220PCLAH1B

Proper refurbishing of the IS220PCLAH1B module can increase its longevity also.

The refurbishing process includes,

Change all aging and commonly failing components.

Apply TIL modification if there is any.

Reflow solder to eliminate dry solder.

Thorough Industrial standard cleaning.

Apply a protective coating, etc.

The CANopen fieldbus interface is provided by the COM-C module via a DE-9 D-sub receptacle connector. It functions as a CANopen master with a 500 Kbaud transmission rate that communicates with one to five Woodward GS6 or GS16 valves.

The following redundancy options are supported by the PCNO:

One I/O pack with one Ethernet connection (no redundancy)

Dual I/O Ethernet connections on a single I/O pack

IS220PCLAH1B

Core Analog I/O for Aero Derivative Turbines

ControlST Version required for IS220PPDAH1B

Install BPPC I/O Upgrade V05.01.03 across the system if currently having ControlST V04.04

Prior to ControlST V04.04 upgrade to ControlST V04.07.08C or CONTROL ST V05.0204C, or the highest available version at the next scheduled outage, then install BPPC I/O Upgrade V05.01.03 across the system

Reliability

I/O pack modules are very reliable and so less prone to damage. But the improper handling and poor storage can affect the module’s functionality, so we recommend keeping the module in static sensitive storage boxes in recommended conditions.

Compatibility

The SPIDG1A CANopen Master Gateway Terminal board is used to mount the PCNO and provide an electronic ID.

Its only connection is to the PCNO, as the CANopen connection is made to the DE-9 D-sub receptacle connector exposed on the PCNO's side. On the PCNO, indicator LEDs provide visual diagnostics.

Processor

The processor board is shared by all Mark VIe Ethernet I/O packs or modules. It includes the following:

Two fully independent 10/100 Ethernet ports with connectors

High-speed processor with RAM and flash memory

Hardware watchdog timer and reset circuit

Internal temperature sensor

Status LEDs

Soft start/current limiter on the input power connector

Local power supplies, including sequencing and monitoring
