Programming and Configuration

Use Connected Components Workbench (CCW) software to program, supporting ladder diagram (LAD), function block diagram (FBD) and structured text (ST).

Built-in real-time clock (RTC), no battery backup is required.

Model Comparison

The main differences with other models in the same series (such as 2080 - LC20 - 20QWB):

2080 - LC20 - 20QBB: Source output (24V DC), suitable for connecting sink loads (such as NPN sensors).

2080 - LC20 - 20QWB: Relay output, suitable for switching AC/DC loads, with larger contact capacity (such as 2A/point).

Typical Applications

Small automation equipment: packaging machines, conveyor belts, material handling systems.

Temperature/pressure control: environmental parameter monitoring through analog input.

Simple motion control: stepper motor positioning, solenoid valve control.

Distributed I/O system: connected to the host computer or other controller via EtherNet/IP.
