Product Details Introduction

1785-L80B processor module (PLC-5/80)

1785-L80B is a high-end processor module of the Rockwell Allen Bradley PLC-5 series, providing high-performance control and multi network communication capabilities for large and complex industrial control systems.

Core parameters (plain text, no links)

Model: 1785-L80B, PLC-5/80 series CPU module.

Processor performance: 16 bit architecture, user program memory 100K words SRAM, supports expandable memory.

Total I/O capability: Maximum 3072 I/O points (any mix), or 3072 in+3072 out complementary configuration.

Communication port:

4 DH+/remote I/O channels (1A/1B/2A/2B), configurable as DH+nodes, remote I/O scanners/adapters.

1 RS-232-C/422-A/423 A serial port (25 pin D-sub), default 2400bps, DF1 protocol, used for programming/monitoring.

Rack and I/O Expansion:

Supports up to 93 I/O racks (local+remote).

A single remote I/O link can have up to 32 racks.

Local I/O and ControlNet extensions are not supported.

Power supply and power consumption: Backboard 5V DC power supply, current 3.3A; maximum power consumption 17.3W.

Physics and installation: occupying one 1771 rack slot; The onboard status LED displays the running/fault/communication status.

Environmental parameters: working temperature 0-60 ° C, humidity 5% -95%, no condensation.

Certification compliance: UL, CE industrial safety and EMC certification.

Product status: discontinued, mainly for refurbishment/spare parts in the market, used for maintenance of large PLC-5 old systems.

Typical applications: Industrial scenarios such as chemical, metallurgical, power, and large-scale production lines that require high I/O capacity, multi network communication, and complex logic control.

The 1785-L80B has the core advantages of a large I/O capacity, 4-channel DH+/remote I/O, and rich communication interfaces, making it one of the most powerful CPUs in the PLC-5 series.
