About 2080-LC20-20QWB

The Allen-Bradley 2080-LC20-20QWB is a Micro 800 Programmable Logic Controller (PLC). This controller is specifically part of the Micro 820 sub-category. This PLC has an embedded 24VDC rated power supply which becomes operational when supplied by an external supply voltage of 120 / 240VAC nominal voltage.

The 2080-LC20-20QWB is part of Allen-Bradley’s latest releases of new generation PLCs that is especially designed to cater the micro-automation niche. This controller features an integrated Twelve (12) 24VDC / VAC discrete inputs; Seven (7) Relay outputs; Four (4) 0-10V (shared with 24V DC) analog input channels and One (1) 0-10VDC analog output channel. This controller also comes with an embedded Ethernet I/P communication interface; One (1) RS232/485 non-isolated combo port that supports CIP Serial, Modbus RTU, ASCII communication protocols; One (1) USB port that may be used for USB -Serial passthrough as well as programming and configuration. Additionally, it has a Pulse Width Modulation (PWM) output with frequency of 5 kHz.

The 2080-LC20-20QWB supports used of a MicroSD card for non-volatile storage. Compatible microSD card is a Class 6 and 10 SDSC and SDHC card with data format of FAT32 / FAT 16. This controller supports insertion of up to 32GB card to the single microSD slot. This module also comes with Two (2) available module plug-in slots for insertion of additional I/O modules.



It has an IP20 enclosure type, a power dissipation of 6 Watts, and a fixed terminal block. The 2080-LC20-20QWB and other products in the Micro820 Controller series, have input-voltage ranging between 120 and 240 Volts AC. They also have embedded communication ports including a 10/100 Base T EtherNet port and an RS-232/RS-485 non-isolated combined serial port. Other features include 19 integrated digital input/output points, and base analog input/output channels including one 0 to 10 Volts analog output and four 24 Volts DC digital inputs.

These controllers also come with 1 analog outputs and 7 relay outputs and the embedded serial ports, including a Modbus RTU Master/Slave port, an ASCII/Binary port, and a CIP Serial port. The Micro820 Programmable Logic Controllers are work best with small standalone machines as well as with remote automation applications requiring flexible communications and I/O abilities. They also have HMI connectivity and RTU applications, and a built-in Real Time Clock (RTC) without a battery. There are selected models fixed with a removable terminal block that help in enhancing the wiring and installation processes. The Allen-Bradley 2080-LC20-20QWB has a 5 KHz PWM Output that helps in controlling the solenoids and valves. Each controller in the Programmable Micro820 series provides embedded non-isolated communication ports and Ethernet ports. They use two Micro800 Plug-in modules for providing the best performance through Micro SD cards by the transferring of program data and log management. These modules can support downloads via a USB port.
