Description

The Allen-Bradley 1766-L32AWAA is part of the MicroLogix 1400 series, a compact Programmable Logic Controller (PLC) that is an ideal solution for micro and small automation requirements.

Here are some of the technical specifications of the Allen Bradley PLC 1766-L32AWAA:

• Analog Input Voltage Range: 0…10.0V DC – 1 LSB
• No. of Analog inputs: 2 Voltage
• Operating Frequency: 47-63 Hz
• Rated Power Consumption: 100VA
• Relay Output operating range: 5 – 125V DC / 5 – 264V AC
• Number of outputs: 16 (Relay)
• Input Operating Range: 79-132V AC
• Number of Inputs: Twenty (20) 120VAC inputs
• Number of I/O: 32
• Inputs: (20) Digital 120V AC, (4) Analog
• Outputs: (12) Relay, (2) Analog
• Operating Power: 110-240V AC
• Channel Count: (20) IP, (12) OP
• Memory: 20 KB

The 1766-L32AWAA has built-in Twenty (20) 120VAC discrete inputs, Two (2) Voltage analog inputs, Twelve (12) Relay outputs and Two (2) Voltage output channels. It also supports installation of up to Seven (7) 1762 I/O modules for expanding the embedded I/O capability of the controller.

The 1766-L32AWAA controller requires 120-240V AC input power and has battery-backed RAM. It supports 32 digital I/O points with 20 digital 120V AC inputs, 12 Relay outputs and 6 analog (12 bits) I/O points with 4 inputs and 2 outputs.
It can be expanded by connecting it with as many as seven 1762 expansion I/O modules.

The 1766-L32AWAA comes with Two (2) serial communication interfaces, with primary serial interface having a 9-pin sub-D RS232C connector while the secondary serial interface having a circular 8-pin mini-DIN physical port. Both serial ports are compatible with a variety of communication protocols such as DH-485, DF1 Full-Duplex, DF1 Half-Duplex Master and Slave, DF1 Radio Modem, Modbus RTU Master and Slave, ASCII and DNP3 Slave.

It is also equipped with One (1) RJ45 port supporting Ethernet I/P protocol for networked communication, supporting transmission speed of 10/100 Mbps communication speed. These ports may be used for programming and communication with Human Machine Interfaces (HMI) and Supervisory Control and Data Acquisition Systems (SCADA).

For communication, it has an isolated RS-232/485 port, an Ethernet port, and a non-isolated RS-232 port that may be accessed using standard web browsers such as Microsoft Internet Explorer, Edge, Google Chrome or Mozilla Firefox.

It also has an embedded real-time clock to provide a reference for applications that need time-based control.

For installation, it has Panel or DIN-Rail mounting options with an open enclosure. It is suitable for use in clean, dry industrial environments with circuits not exceeding Over Voltage Category II.

The 1766-L32AWAA controller’s Ethernet port provides DNP3 protocol support as well as web server and email capabilities. It has 2 Serial ports with DH485/DF1/Modbus RTU/DNP3/ASCII protocol support. It has up to 6 embedded 100 kHz high-speed counters (only on controllers that have DC inputs). It also has 20 KB memory for user programs and data.

This controller’s physical dimensions measure 90 x 180 x 87 millimeters, or 3.5 x 7.08 x 3.43 inches, weight of 2 lbs.
