GE IS220PSVOH1B 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.

Functional Description

The Analog I/O pack (PAIC) is an electrical interface that connects one or two I/O Ethernet networks to an analog input terminal board. 

The PAIC includes a BPPx processor board as well as an acquisition board dedicated to the analog I/O function.

The module has ten analog inputs. The first eight inputs can be set to 5 V or 10 V or 4-20 mA current loop inputs. 

The final two inputs can be set to 1 mA or 4-20 mA current inputs.

The load terminal resistors for current loop inputs are located on the terminal board, and the PAIC senses voltage across these resistors. 

PAICH2 has two current loop outputs ranging from 0 to 20 mA.

 It also includes additional hardware that allows for 0-200 mA current on the first output only.

The I/O pack receives and sends data to the controller via dual RJ-45 Ethernet connectors and is powered by a three-pin connector. 

Field devices are communicated with via a DC-37 pin connector that connects directly to the associated terminal board.

LED indicator lights provide visual diagnostics.
