The Allen-Bradley 1785-L80C15 provides powerful control for large industrial systems. This module handles up to 3072 discrete I/O points. It supports any mix of input and output modules. The processor stores up to 100K words of user memory. It executes bit logic at 0.5 ms per K word. This speed ensures responsive machine control actions. Engineers use this controller for complex manufacturing lines. It operates reliably in demanding production environments worldwide.
Product Procurement & Buyer Guide
This controller solves major pain points for system integrators. The 1785-L80C15 features multiple embedded communication ports. It includes Data Highway Plus and Remote I/O ports. Two ControlNet ports enable high-speed network communication. The ControlNet network runs at 5 Mbps. This speed supports real-time control across distributed equipment. Procurement managers value its flexible I/O addressing modes. You can configure 2-slot, 1-slot, or 1/2-slot addressing. This flexibility accommodates various module density requirements. The processor handles up to 60 universal remote I/O chassis. It also manages a total of 125 I/O chassis across the network. This capacity allows system expansion without replacing hardware. The module works with Bulletin 1771, 1794, and 1746 I/O. It also supports 1791 I/O and intelligent modules. Application engineers appreciate the 100K word memory capacity. This memory supports complex logic and data handling tasks. The processor supports controller redundancy for critical processes. Redundancy ensures continuous operation during a hardware failure.
Step-by-Step Installation Guide
Proper installation ensures optimal performance and longevity. Mount the 1785-L80C15 in the left-most slot of the chassis. Compatible chassis include 1771-A1B, -A2B, -A3B, and -A4B models. The module occupies only a single slot in the rack. Ensure correct keying between positions 40 and 42. Also verify keying between positions 54 and 56. Use RG6 coax cable for the ControlNet network connections. Connect the first ControlNet port to the network tap. Connect the second port for redundant media if needed. The module has dedicated BNC ports for redundant media. Install a 1770-XYC battery in the battery compartment. This battery preserves memory during power loss events. Use memory modules like 1785-ME32 or 1785-ME100 for backup. The serial port uses DF1 protocol for programming connections. Channel 0 provides optical isolation for noise immunity. This isolation works well with RS-422A equipment. Wire the Remote I/O and DH+ networks using twinaxial cable. Set the communication rates as required for your system. Rates include 57.6, 115.2, and 230.4 kbits per second.
