This processor coordinates complex automated systems, managing up to 3072 I/O points and 100 KWords of total memory. We supply this unit in 100% Brand New and original factory condition, providing a critical lifecycle extension for mission-critical industrial architectures that require high-speed data exchange and extensive rack support.

Technical Specifications

The 1785-L80E delivers high-performance processing across multiple communication channels:

Engineering Advantages

• Direct Ethernet Integration: The 1785-L80E features an onboard Ethernet port, allowing the processor to communicate directly with plant-level management systems and peer controllers. This eliminates the need for external bridging hardware, reducing network latency and simplifying system topology.

• Massive I/O Scalability: This processor manages up to 93 I/O racks and 3072 I/O points. It provides the necessary bandwidth to synchronize large-scale distributed I/O across multiple plant floors, solving the pain point of controlling vast production lines from a single CPU.

• Flexible Serial Protocols: The configurable serial port supports RS-232, RS-422A, and RS-423 standards. This versatility allows engineers to interface with a wide variety of legacy peripheral devices, such as bar code scanners, printers, and third-party HMIs, without purchasing additional protocol converters.

• Robust Data Integrity: The unit utilizes the 1770-XYC battery for static RAM backup and supports EEPROM program backup via 1785-ME modules. This dual-layer protection prevents program loss during extended power outages, ensuring the facility restarts immediately upon power restoration.

FAQs

Q: Can I use the 1785-L80E to replace an existing 1785-L80B processor?

A: Yes. The 1785-L80E maintains the core functionality of the L80B but adds an integrated Ethernet port. Ensure your chassis power supply handles the 3.3A backplane load and update your communication drivers to recognize the new Ethernet interface.

Q: What is the benefit of the 100 KWord memory capacity?

A: The expanded memory allows for more extensive data logging, complex recipe storage, and sophisticated PID control loops within the processor itself. This eliminates the need for frequent data uploads to a central server, improving real-time response for data-intensive applications.

Q: Which power supplies are compatible with the 1785-L80E?

A: The 1785-L80E operates within the 1771 universal I/O chassis and requires high-current power supplies such as the 1771-P4S, 1771-P6S, 1771-P4S1, or 1771-P6S1 to support its 3.3A backplane draw.

Q: Is this module brand new or surplus?

A: We guarantee this 1785-L80E is 100% Brand New and original. We provide factory-sealed hardware to ensure maximum reliability and longevity, which is vital for maintaining legacy systems that operate in 24/7 production environments.
