Controller
The MicroLogix 1000 micro-PLC can handle a wide variety of big-time applications at 32 I/O or below, while using only a fraction of the space of a full-size controller — at a fraction of the price. Here are a few reasons why you can choose them with confidence:

• Preconfigured 1K programming and data memory to ease configuration (bit, integer, timers, counters, etc)
• Fast processing allows for typical throughput time of 1.5 ms for a 500-instruction program
• Built-in EEPROM memory retains all of your ladder logic and data if the controller loses power, eliminating the need for battery back-up or separate memory module
• Multiple input commons allow you to use the controller for either sinking or sourcing input devices and multiple output commons provide isolation in multi-voltage output applications.
• RS-232 communication channel allows for simple connectivity to a personal computer for program upload, download and monitoring using multiple protocols, including DF1 Full Duplex
• RTU slave protocol support using DF1 Half-Duplex Slave allows up to 254 notes to communicate with a single master using radio modems, leased-line modems or satellite uplinks
• Peer-to-peer messaging capability allows you to network up to 32 controllers on a DH-485 (using a 1761-NET-AIC module)
• Advanced communications networks, including DeviceNet and EtherNet/IP through the 1761-NET-DNI and 1761-NET-ENI communication modules
• Controllers that have 24V dc inputs include a built-in high-speed counter (6.6 kHz)
• Adjustable DC input filters allow you to customize the input response time and noise rejection to meet your application needs
• Regulatory agency certifications for world-wide market (CE, C-Tick, UL, c-UL, including Class 1 Division 2 Hazardous Location)
This little powerhouse is both inexpensive and compact, with footprints as small as 120mm x 80 mm x 40 mm (4.72" x 3.15" x 1.57"). The analog I/O circuitry is embedded into the base controller, not accomplished through add-on modules, providing compact and cost-effective analog performance.
