IS220PCLAH1A is a Core Analog I/O Module manufactured and designed by General Electric. It is a part of the Mark VIe Series used in distributed control systems. The Core Analog I/O for Aero-derivative gas turbines (PCLA) and related Core Analog (SCLS and SCLT) terminal boards supply the majority of the analog signal I/O needed to run an engine. Thermocouple inputs, RTD inputs, voltage inputs, and inputs and outputs for a 4-20 mA current loop are all provided by PCLA and SCLT. PCLA can be used in control systems with dual controller TMR I/O, dual controller simplex I/O, simplex controller TMR I/O, simplex controller TMR I/O, and simplex controller TMR I/O. One or three connected PCLA fans are signaled by a single SCLT terminal board (s).

Between one or two Ethernet I/O networks and the terminal board, PCLA offers the electrical interface. It has a CPU board that is shared by all Mark VIe distributed I/O. Dual RJ-45 Ethernet connectors and a 28 V dc power connector, designated P1, are used to supply power to the PCLA module.

Field device I/O is connected by 48 and 72 Euro-style box terminals, respectively, on the SCLS and SCLT edges. The 96-pin J3 and 48-pin J4 connectors on SCLS are used to connect to the system. One 68-pin cable that plugs into the J2 connector on SCLS and the JR/JS/JT connector on SCLT connects SCLS and SCLT.


All other Mark VIe I/O packs and controllers work flawlessly with the PCLA module. Frame rates of 10, 20, 40, 80, 160, and 320 ms are intended for use with the PCLA module. As seen in the accompanying table, PCLA provides networking, redundancy, and frame rates.


  • Utilize the four mounting holes located at the four corners to firmly mount the SCLS board.
  • Connectors J3 and J4 on the terminal board should accept the PCLA directly.
  • Utilize the two-side mounting holes to mechanically secure the pack.
  • The SCLT and a plastic insulator are mounted on a sheet metal carrier, which then mounts on a DIN-rail if the SCLT is a configuration component. The SCLT and plastic insulator can instead mount to a sheet metal assembly before being bolted right to a cabinet.
  • Use a single 68-pin cable to connect the SCLS to an optional related SCLT terminal board. One 68-pin cable that connects to the J2 connector on SCLS and the JR/JS/JT connector on SCLT forms the link between the two systems.
  • Connect the JR connector on SCLT to the J2 connector on SCLS using the 68-pin cable when using a simplex arrangement. Connectors on SCLT are coupled by a network connection when using a TMR configuration. For instance, JR1 links to the SCLS-PCLA through the network of R controllers, JS through the network of S controllers, and JT through the network of T controllers.
  • To guarantee adequate cable grounding, it is crucial to fully seat the cable mounting screws into PCLA and SCLT, applying finger-tight pressure only. Failure to secure the connections could prevent PCLA from reading the electronic ID on SCLT and could degrade other signals.
  • Depending on the setup of the machine, connect either one or two Ethernet wires. The module works properly over either port when a single IONet connection is utilized. The R controller's network should be connected to ENET1 if dual connections are being used.
  • The PCLA, however, does not care how an Ethernet connection is made and negotiates correct functionality across any port. The network connection and the connection to the SCLT should match if TMR PCLA modules are available. Cables that go to the SCLT JR connector, for instance, should be present on the PCLA module with the R IONet connection.
  • Verify the SCLS/SCLT shield wire terminals' grounding. Shield ground terminals are often electrically connected to the sheet metal on which the board is mounted on. The ground path for the terminals is then provided by the mounting.
  • Check the power and Ethernet status indicator lights after powering the module with the PCLA's P1 connector.


The PCLA module is a physical assembly made up of two different circuit boards. the processor board shared by all Mark VIe distributed I/O and the BCLA acquisition board. In a simplex setup, BCLA is interfaced with an SCLS and an optional SCLT. Three (SCLS-PCLA) sets are coupled to one SCLT in TMR. The following graphic shows a typical block diagram of the PCLA along with the terminal boards.
