Functional Description
IS200SSCA2AEC is a Simplex Serial Communication Input/Output terminal board developed by General Electric. It is a part of GE Mark VIe system. It is a compact communication solution designed to support multiple channels of data transmission in industrial control systems. This board enhances communication capabilities, making it ideal for applications requiring robust and reliable serial connections.
Features
- Multi-Channel Serial Communication: It supports up to six independent serial communication channels. These channels allow for concurrent data transmission and reception across multiple devices, reducing bottlenecks and enhancing communication efficiency in distributed control systems. This feature is particularly beneficial in environments where multiple serial interfaces are required, such as turbine control, auxiliary systems monitoring, and remote device interfacing.
- Flexible Signaling Options: Each channel can be configured to operate in RS-232C, RS-485, or RS-422 modes. This flexibility ensures compatibility with a wide range of devices, including sensors, actuators, and third-party communication modules. RS-232C provides standard point-to-point communication, while RS-485 and RS-422 allow for longer-distance, multi-drop communication with higher noise immunity—ideal for industrial environments.
- Seamless Integration with PSCA I/O Pack: The board is designed to work in conjunction with the PSCA I/O pack, which connects directly via the DC-37 pin connector. The I/O pack facilitates communication with the Mark VIe controller over an Ethernet network, providing high-speed data transfer and system-wide connectivity. This integration simplifies system configuration, reduces wiring complexity, and enhances the overall communication infrastructure.
- Robust and Reliable Design: Built with GE’s engineering expertise, designed to operate reliably in demanding industrial environments, ensuring long service life and minimal downtime. Its design includes safeguards against signal interference, ensuring consistent communication even in electrically noisy conditions.
Installation Guidelines
- No Shield Termination Strip: The terminal board features a design that does not require a shield termination strip, simplifying the installation process and reducing potential points of failure.
- Mounting Options: The board can be easily mounted on a DIN-rail using a sheet metal carrier and plastic insulator mount. This assembly provides flexibility as it can also be bolted directly into a cabinet, making it adaptable to various installation environments.
- Terminal Block Options: The terminal board is compatible with two types of Euro-Block terminal blocks:
- SSCAH1: This variant includes a permanently mounted terminal block with a total of 48 terminals, allowing for fixed connections.
- SSCAH2: This version features a right-angle header that accepts a range of commercially available pluggable terminal blocks, also with 48 terminals. This flexibility in terminal block design enables easier wiring and maintenance.
Wiring and Shielding
- Wiring Specifications: The board typically utilizes #18 AWG (American Wire Gauge) wiring, specifically shielded twisted pair wiring. This type of wiring is essential for maintaining signal integrity and reducing electromagnetic interference (EMI) in communication lines.
- Shield Termination: The termination for the I/O cable shield is accomplished through an external mounting bracket, which may be supplied by the customer or sourced from GE. Proper termination is crucial for minimizing noise and ensuring reliable communication.
- Ground Connections: The board features mounting holes E1 and E2 for the chassis ground connection. It is essential to connect one of the SCOM terminals (terminals 37-48) to a suitable shield ground. This connection aids in the effective grounding of the system, further enhancing signal quality and reliability.
