Cost-Effective & Economical Solution:Part of Delta’s EC3 series economical PLCs, designed for budget-conscious small 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.
20 Integrated I/O Points – Maximum Input Points in EC3 Series:Features 12 digital inputs + 8 relay outputs, providing the highest number of input points among standard EC3 models—ideal for systems with multiple sensors, limit switches, or control buttons.
Relay Outputs – High Load Compatibility:8 relay outputs with 2A @ 250VAC / 2A @ 30VDC contact rating—capable of driving solenoids, contactors, lamps, and small motors (AC or DC), offering great application flexibility.
Dual Communication Ports with MODBUS RTU Support:Equipped with RS-232 and RS-485 ports, supports MODBUS ASCII/RTU slave mode, enabling seamless integration with HMI or SCADA systems for monitoring and control.
