GE IC660ELB921M Product Specification
Product Overview
The GE IC660ELB921M is a high-performance enhanced logic bus interface module designed for GE’s 90-30 Series Programmable Logic Controller (PLC) platform. Engineered to bridge field devices with higher-level control systems, this module serves as a critical component in industrial automation architectures, enabling seamless data exchange and real-time process monitoring. As part of GE’s legacy 90-30 Series, the GE IC660ELB921M combines robust hardware with flexible software configuration, making it ideal for applications requiring reliable communication and precise control in industries such as manufacturing, power generation, and oil & gas.
Featuring a 32-bit microprocessor and dual-port memory architecture, the GE IC660ELB921M supports up to 128 I/O points with advanced error-checking capabilities, ensuring data integrity in harsh industrial environments. Its Enhanced Logic Bus (ELB) interface enables high-speed communication (up to 10 Mbps) with other 90-30 Series modules, while the built-in RS-232/485 ports facilitate integration with external devices like HMIs and SCADA systems. The module’s compact design (178 mm × 102 mm × 254 mm) and rugged metal enclosure (IP20 protection) allow for easy rack mounting and reliable operation in temperatures ranging from -40°C to +70°C.
In automation systems, the GE IC660ELB921M acts as a communication hub, translating field signals into process data for the PLC’s central processor. Its support for modular expansion—via additional I/O modules and communication gateways—makes it scalable for both small-scale machinery and complex plant-wide systems. By combining real-time data processing with diagnostic capabilities, the GE IC660ELB921M enhances system uptime, reduces maintenance costs, and supports compliance with industry standards like ISO 9001.
