Allen-Bradley 1761-L32AAA

The 1761-L32AAA is a PLC controller manufactured by Allen Bradley as part of the MicroLogix 1000 controller series. The 1761-L32AAA controller features an input and output count of 32 points, with a power supply maximum inrush current of 30 amperes for 8 milliseconds. It is an output type Triac controller, and it comes with a power supply usage of 120 – 240 volts AC. It also features a master-control relay safety feature. Its recommended storage temperature range is -40 to 85 degrees Celsius, while the non-condensing operating humidity is 5 – 95 percent. This PLC controller unit has a vibration resistance as well as a non-operating mode vibration resistance of 5 – 2000 hertz. Allen Bradley 1761-L32AAA PLC controller meets and adheres to various certifications, including the CUL Class 1 Division 2 Groups. It is also rated and listed for compliance with the UL and CE/RCM/EAC standards. The 1761-L32AAA controller unit features a terminal screw torque of 0.9 – 8.0 pounds on an inch with an electrostatic discharge at EN 61000-2 rated at 8000 volts. It has an isolation voltage rating of 1500 volts AC, with a 1K EEPROM memory size and type suitable for handling of approximately 737 instruction words and 437 data words. These Allen-Bradley MicroLogix 1000 controller series feature a maximum of 5 control levels. They are small in size and offer excellent performance. These controllers, including the 1761-L32AAA PLC controller, provide control capabilities, and they are cost-effective. They also fit well in small spaces and are powerful enough to handle a wide range of applications.

The Allen-Bradley 1761-L32AAA is a PLC controller from the MicroLogix 1000 series. It has a compact structure with integrated, inputs, outputs, and communication ports. The 1761-L32AAA has 32 I/O points (20 points for ac inputs, 10 points for triac outputs, and two points for relay outputs). Input voltage for the controller is 120 VAC and the controller needs a unit power supply of 120-240V AC. This unit is an AC-oriented device with AC inputs and triac outputs which can be used to switch various types of loads. The controller's outputs should be protected by a surge suppression device, especially for inductive loads. There is a limit in inrush current while the load is switched on and off, and it is rated to 30 amperes for 8 milliseconds. The response time for AC input is a maximum of 20 milliseconds. The maximum load current for triac outputs is 0.5 amperes per point at 131 degrees Fahrenheit and 1.0 amperes per point at 86 degrees Fahrenheit. This controller has two types of memory, RAM and EEPROM. EEPROM has a 1K capacity or approximately 737 instruction words and 437 data words. It keeps the ladder program that is used to run controller I/O and to provide proper operation for connected devices. For communication purposes, this unit supports DF1 and DH-485 protocol and automatically recognizes which one is active. The operating temperature should be +32 to +131 degrees Fahrenheit, for horizontal mounting, and +32 to +104 degrees Fahrenheit for vertical mounting. The storage temperature range is from -40 to +185 degrees Fahrenheit. This processor can be mounted on a panel or a DIN-rail.
