Compact All-in-One Design:Integrates power supply, CPU, and I/O in a single unit with 20 digital points (12 inputs + 8 outputs), ideal for space-constrained installations in small control panels.
Relay Outputs for Wide Load Compatibility:Features relay-type outputs capable of switching both AC and DC loads (up to AC 250V / DC 30V), suitable for driving contactors, solenoid valves, lamps, and small motors with flexible wiring options.
High-Speed Processing & Response:Supports fast scan cycles, hardware interrupts, high-speed counting (up to 100 kHz), and pulse train output (PTO/PWM), ideal for positioning and speed measurement in small-scale automation.
Easy Programming & Commissioning:Programmed using Siemens STEP 7-Micro/WIN SMART software, supporting LAD, FBD, and STL languages. User-friendly interface simplifies development and debugging, especially for entry-to-mid-level users.
Scalable System Architecture:Supports up to 7 expansion modules (e.g., analog I/O, digital I/O, communication boards), allowing flexible system scalability based on application requirements.
Industrial-Grade Reliability:Operates reliably from 0°C to 55°C with strong EMC immunity, designed for stable long-term operation in harsh industrial environments.
