Product Description
The IS220PSCAH1A is a Serial Communication I/O Pack that is part of the Mark VIe Speedtronic system from General Electric. One of the last Speedtronic systems released by GE, the Mark VIe included improved running and startup reliability with automatically-maintained emissions control. This system offered modern Fieldbus technology and equipment-prediction capabilities far more advanced than any previous Speedtronic system.
The IS220PSCAH1A is used within the Mark VIe system to provide an interface between a serial communication terminal board and up to two I/O Ethernet networks. The module receives inputs using dual RJ-45 Ethernet connectors and a single three-pin power input. Outputs are made through a DC-62 pin connector through the terminal board.
The IS220PSCAH1A is one of two PSCA modules available. It contains a BPPB processor board.
The IS220PSCAH1A has two Ethernet ports. These support Ethernet Modbus Master Protocol, which can also be used in a Simplex networking configuration. ToolboxST allows the attachment of up to 18 Ethernet Modbus stations to a single PSCA module.
The IS220PSCAH1A has several alarms specific to the I/O pack. This includes Comm Port # Node # communication failure--No Response, Comm Port # Node # communication--Bad data, Configuration problem port #, and Electric Drive Port # Save Command failed. Causes and solutions for these alarm states can be found using GE’s Mark VIe and Mark VIeS Control System Guide for General-purpose Applications, Vol II (GEH-6721, Vol II.)
For more detailed information regarding the installation or maintenance of this module, please refer to GE publications like manuals or data sheets.
