Micro820 2080-LC20-20AWBR PLC Controller RTB

Overview

The 2080-LC20-20AWBR is a Micro820 programmable logic controller with a 20-point configuration. It features 8 110-120V AC input points, 4 configurable analog inputs (with thermistor voltage reference output), 7 relay outputs, and 1 analog output. It is equipped with an embedded 10/100 Base-T EtherNet port (RJ-45), supporting Modbus/TCP and EtherNet/IP protocols; It also features an embedded non-isolated RS232/RS485 multiplexed serial port, supporting the Modbus RTU protocol and CIP serial port.

FAQ:

1. What is the voltage range and response time supported by the 8 AC input points of the 2080-LC20-20AWBR?

1. Voltage range: The 8 AC input points are rated for 120V AC, with a minimum input voltage of 79V AC and a maximum of 125V AC. This voltage range is suitable for common low-voltage AC industrial control scenarios and can meet the signal input needs of most small automation equipment.
2. Response time: Its input delay time constant is up to 22ms. This response time is within the conventional level of small PLCs and can meet the needs of small and medium-sized automation scenarios such as packaging equipment and small conveyor lines that do not have extremely stringent signal feedback speed requirements. If it is used in high-precision and high-speed control scenarios, it is necessary to evaluate the suitability in advance.

2.Are the signal types (such as 0-10V/4-20mA) of the 4 analog input channels of the 2080-LC20-20AWBR configurable?

The 4 analog input channels of 2080-LC20-20AWBR are configurable, and its core supports configuration related to voltage signals and thermistor temperature inputs, but does not support 4-20mA current signal types:

0 – 10V DC voltage signal: This is the basic configurable voltage signal type of this analog input channel. It is adapted to common industrial analog sensor signals, such as the 0 – 10V standard signals output by some pressure sensors and liquid level sensors. It can meet the conventional analog detection needs in small automation scenarios.
Thermistor temperature signal: The 4 analog input channels also have thermistor voltage reference output function, which can be configured to access the temperature detection signal related to the 10k thermistor. This configuration allows it to be directly adapted to thermistor temperature sensors without the need for additional signal conversion modules to collect the temperature of the environment or equipment. It is commonly used in temperature monitoring scenarios of building automation and small mechanical equipment.

3.What is the maximum program capacity (bytes/step) and data storage capacity supported by 2080-LC20-20AWBR?

1. Program capacity: 100KB (about 100,000 steps)
2. Data storage: non-volatile 8KB, volatile 20KB
3. Expansion: Supports up to 32GB microSD card
