The entire controller measures 7.87 x 2.87 x 3.15 inches. It also has several LED indicators, namely status LEDs, input LEDs, and output LEDs. It also has a 1K EEPROM memory that can handle up to 437 data-table words and 737 instruction words. The controller also has a maximum of 40 timers and 32 counters. Its typical program scan time/Kword is 2 milliseconds and the typical I/O scan time is 0.21 milliseconds. It has a 24 Volts DC sensor power with a maximum of 200 mA and with a maximum capacitive load of 200 µF.

The line voltage of the 1761-L20AWA-5A controller is 120/240 Volts AC. It has a real input power of 12 Watts at 120 Volts AC and 13 Watts at 240 Volts AC and an apparent input power of 20 VA at 120 Volts AC and 27 VA at 240 Volts AC. The transformer load available for this controller is 30 VA at 120 Volts AC and 33 VA at 240 Volts AC. Its digital input voltage is 120 Volts AC, it has an input current range of 0 to 20 mA -1LSB and an input voltage range of -10.5 to 10.5 Volts -1LSB. Output voltage range of this controller is 0 to 10Volts -1LSB and output current range is 4 to 20 mA -1LSB. The 1761-L20AWA-5A controller has the following response time for AC inputs: 8 milliseconds for nominal filter setting and an ON and OFF delay of a maximum of 20 milliseconds for both. It has a minimum power cycle of 50,000 and an isolation rating of 1500 Volts AC. The controller has an operating temperature of 0 to 55 Degrees Celsius when mounted horizontally and 0 to 40 Degrees Celsius when mounted vertically and a non-operating temperature of -40 to 85 Degrees Celsius. It has an operating shock of 10 g and a non-operating shock of 20 g. It also has a 2.5 g operating vibration and a 5 g non-operating vibration. The controller has a non-condensing relative humidity of 5 to 95%.

The 1761-L20AWA-5A is an Allen-Bradley manufactured MicroLogix 1000 Programmable Logic Controller (PLC). This controller features discrete and analog control capability as it is provided with Twelve (12) Discrete Inputs, Eight 8) Relay Output, Four (4) Analog Inputs and One (1) Analog Output.

This controller is capable of being programmed to perform Basic logical sequences such as Bit Logic Operation, Timers and Counter instructions. Aside from bit logic operations, Comparison, Math or Arithmetic operations, Data Handling Instructions, Program Flow Control, Message Instructions and other operations.

The analog input signal type compatible for this controller are Voltage signal with range of -10.5 to 10.5 VDC and Current signals with range of -21 to 21 mA. The analog data is converted with a resolution of 16-bit signed integer with input coding of -32767 to +32767. This analog data may processed with the integrated Scale instruction to produce the appropriate engineering value. This analog input may be assigned as the Process Variable of a PID controller. The analog output provide 0-10VDC Voltage or 4-20mA Current signals. Ideal for used with modulating Final Control Elements (FCE), Indicators, Recorders, Converters, and Isolators.

This controller supports vertical or horizontal mounting with the use of a DIN Rail or mounting screw option. When wiring the controller, use #14 to #22 AWG Solid wires or #16 to #22 AWG Stranded wires.
