Cost-Effective & Economical Solution:Part of Delta’s EC3 series economical PLCs, designed for budget-conscious small to medium automation systems, offering reliable control at low cost.
Wide-Range AC Power Supply (100–240V):Operates on standard AC mains voltage (50/60Hz), compatible with global power standards—no external DC power supply required.
Direct AC Input Connection – Simplified Wiring:Inputs accept AC 100–240V signals directly from push buttons, switches, or sensors—eliminating the need for external DC power or level-shifting circuits.
48 Integrated I/O Points – Highest I/O Capacity in EC3 Series:Features 28 digital inputs + 20 transistor outputs, providing one of the highest I/O counts in the EC3 series—ideal for systems requiring multiple sensors, limit switches, push buttons, and various actuators.
Transistor Outputs – Fast Response & Long Life:20-channel NPN transistor (sink type) outputs offer microsecond-level response time and support high-frequency switching—no mechanical wear, significantly longer lifespan than relay outputs.
Ideal for Driving DC Loads & Solid-State Devices:Perfectly suited for driving Solid-State Relays (SSR), relay coils, solenoid drivers, LED indicators, etc.—widely used in heating control, pneumatic systems, servo enable circuits, and more.
