IS220PDIAH1A - Discrete Contact Input Terminal Board

Functional Description

IS220PAOCH1A is an Analog Output Module manufactured by General Electric as part of Mark VIe used in gas turbine control management systems. An electrical interface between one or two I/O Ethernet networks and an analog output terminal board is provided by the Analog Output (PAOC). A BPPx processor board and an acquisition board pair tailored to the analog output function are both present in the PAOC. Up to eight simplexes, 0-20 mA current loop outputs can be provided by the PAOC, which also has an analog to digital converter for each output's current feedback. Dual RJ-45 Ethernet connectors and a three-pin power input serve as the PAOC's inputs. The related terminal board connector is directly connected to the output via a DC-37 pin connector. Indicator LEDs are used to display visual diagnostics.

Compatibility

1. There is a BPPB processor board within the PAOCH1A.

2. The controlST* Software Suite V04.06 and later supports the functionally compatible BPPC found in the PAOCH1B.

3. Only the analog output terminal boards TBAOH1C and STAOH1A/H2A indicated in the accompanying table are compatible with the PAOC.

Installation

1. Mount the selected terminal board firmly.

1. Directly connect the PAOC I/O pack(s) to the connector on the terminal board (s).

2. Using the threaded studs next to the Ethernet ports, mechanically fasten the I/O pack(s). The studs slip into a mounting bracket made for the particular style of the terminal board.

3. It is important to position the bracket such that the DC-37 pin connector connecting the I/O pack and the terminal board is not subjected to right-angle forces. In the course of the product's service life, the adjustment should only be necessary once.

4. Depending on the setup of the machine, connect either one or two Ethernet wires. Either port will work with the I/O pack. If When using dual connections, it is customary to link ENET1 to the network connected to the R controller.

5. Connect the connector on the side of the PAOC to provide power to the I/O pack. Because the I/O pack has an inherent soft-start feature that regulates current inrush on power application, it is not essential to turn off the power before plugging the cable in.

6. If necessary, set up the I/O pack using the ToolboxST* program. Press F1 to bring up the Component Editor's help menu.
