The 1761-L32AAA is an Allen-Bradley MicroLogix controller. This controller is specifically the art of the MicroLogix 1000 series, mainly used for micro and small automation requirements. It is categorized as a compact or “shoebox” controller that comes with an integrated power supply, embedded I/O channels, integrated memory, and a communication interface. Specifically, the 1761-L32AAA has an embedded power supply that internally powers the controller’s circuitry. This embedded power supply requires an external supply voltage of 120 / 240 VAC and accepts a voltage range of 85-264 VAC along with a frequency range of 47-63 Hz. The integrated I/O available to this controller includes 120 VAC / 240 VAC. It has built-in Twenty (20) 120 VAC Digital Inputs, Ten (10) TRIAC Outputs, and Two (2) Relay Outputs. It also has One (1) RS232 communication port that is configurable to communicate using the Allen-Bradley DF1 protocol. The built-in memory available to this controller is 1K Electrically Erasable Programmable Read-Only Memory (EEPROM). This memory is internally partitioned as 737 instruction words and 437 data words. It can be programmed using the Ladder programing language which is one of the recognized programming languages by the IEC 61131 standard. For installation, this controller both supports DIN-rail and Panel mounting. It measures 200 mm (7.87 in) length; 73 mm (2.87 in) in depth and 80 mm (3.15 in) in height. Recommended minimum mounting clearance is 50.8 mm (2 in.) on all sides of the controller.
