MicroLogix 1100 Programmable Logic Controller Systems

MicroLogix™ 1100 Programmable Logic Controller Systems add embedded EtherNet/IP™, on-line editing, and an LCD panel to the MicroLogix family. The built-in LCD panel shows controller status, I/O status, and simple operator messages. With 2 analog inputs, 10 digital inputs and 6 digital outputs, the MicroLogix 1100 controller can handle a wide variety of tasks.

System Overview

The MicroLogix 1000 family are inexpensive compact PLCs. Its features configuration of 10 digital I/O (6 inputs and  outputs), 16 digital I/O (10 inputs and 6 outputs), 25 I/O (12 digital inputs, 4 analog inputs, 8 digital outputs, and 1 analog output), or 32 digital I/O (20 inputs and 12 outputs) in multiple electrical configurations of digital I/O.

They are best suited for I/O options and electrical configurations.

Features

• Small design— Ideal for panels with small space.
• Several communication networks:
• Configuration with a RS-232-C port for: DF1 protocol directly connecting into an operator interface or device for programming; communications through a 1761-NET-AIC converter for DH-485 Communications;  1761-NET-DNI for communications with DeviceNet; 1761-NET-ENI provides networking to Ethernet/IP or for SCADA applications for half-duplex slave protocol.
• Choose your programming device with easy programming. These controllers can be programmed in ladder logic with MicroLogix 1000 A.I. Series Software^®, PLC 500 A. I. Series Programming Software, RSLogix 500™ Windows Programming Software, or the MicroLogix Hand-Held Programmer (1761-HHP-B30).
• This programming language is based on relay ladder wiring diagrams to your control program simplifying troubleshooting of your control program.
• Extensive instruction set—Over 65 instructions including simple bit, timer, and counter instructions, as well as instructions for powerful applications like sequencers, high-speed counter, and shift registers.
• Rapid—The time of execution for a typical 500-instruction program is only 1.56 ms.

Product Design

The MicroLogix 1000 comes in a single package with processor, power supply, and all its I/O circuits packaged.

Four I/O sizes (10, 16, 25, and 32) are useful in many situations.

• Electrical needs works with various electrical configurations of digital I/O:
  • 24V DC inputs and relay outputs with a 24V DC power supply.
  • 24V DC inputs and 24V DC FET and relay outputs with a 24V DC power supply.
  • 24V DC inputs and relay outputs with a 120/240V AC power supply.
  • 24V AC inputs and relay outputs with a 120/240V AC power supply.
  • 120V AC inputs and relay outputs with a 120/240V AC power supply.
  • 120V AC inputs and triAC and relay outputs with a 120/240V AC power supply.
• Isolated relay contact outputs (at least two per controller). Allow outputs on the same unit to switch different control voltages.
• The 25-I/O models include 4 analog inputs and an analog output in addition to the 12 digital inputs and the 8 digital (contact) outputs.
