PRODUCT INFORMATION
Product Overview
General Electric IS220PIOAH1A is an Arcnet I/O pack designed for Mark VI and Mark VIe excitation control systems. This module operates as a communications bridge between local terminal hardware and the main processor controller board. The unit features an internal processor board running a QNX operating system on a 32-bit RISC processor. This CPU runs at 266 MHz to execute onboard algorithmic computations and digitize incoming sensor signals rapidly.
The IS220PIOAH1A mounts directly onto the JPDV interface terminal rack without standard terminal board hardware. It provides dual 100 MB Ethernet communication ports alongside a dedicated three-pin power supply input. Operating power is rated at a typical 28 V dc supply level across standard plant environments. An integrated ambient temperature sensor monitors internal conditions and triggers an alarm when temperature thresholds are exceeded.
