FUNCTIONAL DESCRIPTION:

IS220PSCAH1BD is a Serial Modbus Communication I/O Module manufactured and designed by General Electric as part of the Mark VIe Series used in distributed control systems. The Serial Modbus Communication Input/Output (PSCA) pack provides the electrical interface between one or two I/O Ethernet networks and a serial communications terminal board. The pack contains a processor board common to all Mark VIe distributed I/O packs and a serial communications board. The communications board contains six serial transceiver channels, each of which can be individually configured to comply with RS-232, RS-422, or RS-485 half-duplex standards. Input to the pack is through dual RJ45 Ethernet connectors and a three-pin power input. Output is through a DC-62 pin connector that connects directly with the associated terminal board connector. One of the Ethernet ports can be used to support Ethernet Modbus communication on Simplex Networks. Visual diagnostics are provided through indicator LEDs.

INSTALLATION:

• Mechanically secure the packs using the threaded inserts adjacent to the Ethernet ports. The inserts connect with a mounting bracket specific to the terminal board type. The bracket location should be adjusted such that there is no right angle force applied to the DC-62 pin connector between the pack and the terminal board. The adjustment should only be required once in the life of the product.

• Plug in one or two Ethernet cables depending on the system configuration. The pack operates over either port. If dual connections are used, standard practice is to hook ENET1 to the network associated with the R controller, however, the PSCA is not sensitive to Ethernet connections and will negotiate proper operation over either port.

• Apply power to the pack by plugging in the connector on the side of the pack. It is not necessary to remove power from the cable before plugging it in because the I/O pack has inherent soft-start capability that controls current inrush on power application.

FEATURES:

• Serial Transceiver Channels: The communications board within the pack is equipped with six serial transceiver channels, each capable of individual configuration to comply with RS-232, RS-422, or RS-485 half duplex standards. This flexibility allows for seamless integration with a wide range of devices and communication protocols, enhancing interoperability within the system.

• Input and Output Connectivity: Input to the pack is facilitated through dual RJ45 Ethernet connectors and a three-pin power input, providing convenient access to network connections and power sources. Output is delivered through a DC-62 pin connector, establishing a direct connection with the associated terminal board connector, ensuring efficient transmission of data between components.

• Ethernet Modbus Communication Support: One of the Ethernet ports integrated into the pack can be utilized to support Ethernet Modbus communication on Simplex Networks. This feature enables efficient data exchange and communication between devices using the Modbus protocol, enhancing system connectivity and interoperability.

• Visual and Local Diagnostic Capabilities: Visual diagnostics are provided through indicator LEDs, offering real-time feedback on the operational status and performance of the PSCA pack. Additionally, local diagnostic serial communications are possible through an infrared port, allowing for convenient access to diagnostic information and troubleshooting capabilities, ensuring the reliability and integrity of communication processes.

• Applications of the Pack: Finds applications in various industrial settings where reliable and efficient communication between serial devices and Ethernet networks is essential. It is commonly utilized in control systems for power generation, industrial automation, and process control applications, where seamless integration and interoperability are critical for optimal system performance.

FREQUENTLY ASKED QUESTIONS:

What is the purpose of the DC-62 pin connector on the underside of the I/O pack?

The DC-62 pin connector serves to directly connect the I/O pack to a discrete output terminal board, facilitating the transmission of signals between the pack and the board.

What is the primary system interface connector?

The primary system interface connector is an RJ45 Ethernet connector labeled ENET1. This connector serves as the primary means of communication between the pack and the system.

What is the purpose of the second RJ45 Ethernet connector on the pack?

The second RJ45 Ethernet connector, labeled ENET2, functions as the redundant or secondary system interface. It provides an alternative connection option for redundancy or backup purposes in case the primary interface (ENET1) encounters issues.
