The 1761-L20BWA-5A is an Allen-Bradley MicroLogix 1000 Programmable Controller. It has a 120 to 240 Volts AC power supply, 4 analog inputs, and 1 analog output, and it comes with several benefits. The 1761-L20BWA-5A module needs less panel space than other controllers. It can support several communication networks. An RS-232 port connects the 1761-L20BWA-5A to a peer-to-peer network. It uses the Device Net Interface (DNI) for fast response, low cost, and reliability. SCADA and point-to-point communications are also available via the DF1 Half- and Full-Duplex protocols.
Simple programming is possible with this module. The 1761-L20BWA-5A has a large user memory that can use ladder logic with the Micrologic 1000 A.I. Series Software®, and Windows Programming Software, among others. The language choices for this module include documentation and software that are available in five languages. The 1761-L20BWA-5A controller has an execution time of 1.56 milliseconds and a throughput of 1.85 milliseconds for a typical 500 instructions program. Its input/output choices include AC, DC, or analog (current or voltage) inputs, and its output options include relay, TRIAC, MOSFET and analog (current or voltage) outputs. The module comes with a large instruction set. The 1761-L20BWA-5A controller has 12 basic logic instructions, 43 applied control instructions, and 14 advanced application-specific instructions.
