1750 Series PLC

The 1750 Series is one of Allen Bradley's earliest programmable logic controller (PLC) families. It is a modular platform built from individual boards and modules that together form a complete control system, from processing and memory through to field-level input and output.

Products in this series

The series includes a range of module types covering the core functions of a PLC system:

• Processing and memory — processor modules, program memory, retentive memory, address and instruction decoders, and storage cable assemblies.
• Input and output — AC/DC input, AC output boards, quad AC output modules, and output registers.
• Switching and relays — dual relay 5A modules and quad AC switches.
• Counting and timing — bidirectional counters and I/O timers.
• Monitoring — I/O monitor modules.

All products in this series are manufactured by Allen Bradley and identified by 1750-series part numbers.
