Features:

  • Bridge Between I/O Ethernet Networks and Serial Communication Terminal Boards
  • Integrates Six Independently Configurable Serial Transceiver Channels with Dual Ethernet Modbus Support
  • Functions Seamlessly Within Mark VIe Distributed Control Architectures
The General Electric IS220PSCAH1A Communication I/O Module serves as the Serial Modbus Communication I/O Pack in a Mark VIe control system, providing the critical electrical interface between one or two I/O Ethernet networks and a serial communications terminal board. It continuously manages data exchange between the control system and external serial devices through six independently configurable channels, each supporting RS-232, RS-422, or RS-485 half-duplex standards, while dual RJ45 Ethernet connectors enable high-speed networked communication across the IONet infrastructure. Seamless protocol conversion is standard with the IS220PSCAH1A, however utilizing the optional Ethernet Modbus Master capability on simplex networks will allow direct integration with third-party intelligent devices such as sensors, actuators, and smart meters. The IS220PSCAH1A has incorporated advanced self-diagnostic capabilities in addition to comprehensive analog input monitoring for position and pressure parameters within the Mark VIe rack.

The IS220PSCAH1A provides essential communication functions common to the entire distributed I/O architecture, and is a critical component of the data pathway, directly affecting the proper, normal operation of the overall turbine control system. One IS220PSCAH1A pack is typically deployed per communication node depending on the required serial connectivity scope. The IS220PSCAH1A occupies a standard I/O pack form factor and mounts directly onto its associated IS200SSCAH1A or IS200SSCAH2A terminal board through a DC-62 pin connector.

For expanded communication requirements, the Mark VIe System supports multiple IS220PSCAH1A modules distributed across the I/O network. In addition to standard serial Modbus RTU master operation, the redundant network configuration also performs automatic failover. The Mark VIe distributed I/O architecture executes communication management using the internal BPPC processor board common to all Mark VIe I/O packs. Using this method, the control system continually monitors the health of all communication paths. If the system detects that the primary Ethernet network is no longer providing stable data transmission, it will automatically reroute critical communications through the secondary network and generate appropriate system alarms.

The IS220PSCAH1A General Electric Communication I/O Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Description
IS220PSCAH1A is a Serial Modbus Communication I/O Module manufactured by General Electric as a part of the Mark VIe series used in gas turbine control systems. The IS220PSCAH1A power supply gives you consistent, reliable, switched DC power at linear power supply prices. This module uses efficient switching technology to produce the most power in the smallest space while generating a minimum amount of heat. The IS220PSCAH1A is designed to provide precisely regulated output power suitable for battery charging applications, making it ideal for maintaining backup power systems in critical industrial environments.

This IS220PSCAH1A module features constant-current short circuit protection that limits the output current as the voltage is reduced to safely protect your control components from direct shorts and device failures. Once the short is corrected, the IS220PSCAH1A automatically resumes supplying full-voltage power, ensuring continuous operation of your gas turbine control systems. The extra-sturdy DIN rail mounts and removable plug connections of the IS220PSCAH1A make installation a breeze in demanding industrial settings.

The IS220PSCAH1A meets UL/cUL 60950, 508, and 1604* (Class I, Div. 2) standards, making the IS220PSCAH1A suitable for practically any industrial control application. This IS220PSCAH1A is specifically designed for handling serial Modbus communication in gas turbine control systems, solving the critical challenge of reliable power delivery and data communication in harsh industrial environments. The IS220PSCAH1A addresses the need for robust, fault-tolerant power supplies that can maintain stable operations while protecting sensitive control components from electrical faults.
