MicroLogix 1000 Control System

Bulletin 1761 MicroLogix™ 1000 Controllers are the most compact of the MicroLogix family. This controller fits a wide variety of applications up to 32 I/O points, while using a fraction of the space of a full-size controller. It contains embedded analog I/O, providing compact and cost-effective analog performance.


  • Available in 10-point, 16-point or 32-point digital I/O versions
  • Analog versions available with 20 digital I/O points, 4 analog inputs (two voltage and two current) and 1 analog output (configurable for either voltage or current)
  • Provides a compact form factor, with footprints as small as 120 mm x 80 mm x 40 mm (4.72 in. x 3.15 in. x 1.57 in.)
  • Offers fast processing with typical throughput time of 1.5 ms for a 500-instruction program
  • Preconfigured 1 KB program and data memory to ease configuration
  • Includes built-in EEPROM memory; no need for battery back-up or separate memory module
  • Provides peer-to-peer messaging (up to 32 controllers on a DH-485 network) through a 1761-NET-AIC communication interface
  • Communicates via DeviceNet™ and EtherNet/IP™ through 1761-NET-DNI and 1761-NET-ENI communication interfaces
  • Includes a built-in high-speed counter (only on controllers with 24V DC inputs)
  • Lets you customize input response time and noise rejection using adjustable DC input filters
  • Supports simple connectivity through RS-232 communication channel to a PC for program upload, download and monitoring
