Functional Features
All-in-one design combines CPU, power supply, and I/O in one compact unit. High-speed counter inputs support motion and process applications. Built-in RS-232 port supports SNP and Modbus RTU protocols. LED indicators for every input and output point simplify troubleshooting. Expandable up to 140 points with additional modules.
Application Scenarios
Packaging machinery, material handling conveyors, small-scale pump stations, machine control, assembly lines, and OEM equipment requiring compact standalone control.
Performance Parameters
0.1 ms typical input response time supports fast signal detection. 12 KB user memory accommodates substantial control programs. 2.0 A maximum switching current per relay output handles standard industrial loads.
Material Composition
Industrial-grade housing with integrated CPU circuitry, power supply components, relay outputs, and LED indicator array.
Structural Characteristics
Compact self-contained PLC unit with removable terminal blocks. DIN rail or panel mounting options. Front-facing LEDs for all I/O points and system status.
Working Principle
The integrated CPU executes user-programmed logic stored in non-volatile memory. Input circuits receive 24 VDC signals from field devices. Output circuits energize relays based on logic execution results. The internal power supply converts 120/240 VAC to operating voltages for the CPU and I/O circuits.
Installation Requirements
Mount on DIN rail or panel. Wire 24 VDC inputs and relay outputs to removable terminal blocks. Program via RS-232 port using Proficy Machine Edition software.
