8DI + 8 Relay Outputs – Balanced and Practical I/O Configuration:Provides 8 digital inputs (24V DC) and 8 relay outputs, ideal for applications requiring both signal acquisition and control output expansion.
Relay Outputs – Compatible with AC & DC Loads:Features electromechanical relay contacts (dry contacts) that can switch both AC and DC loads (up to 250V AC / 30V DC), directly driving contactors, solenoids, lamps, and small motors.
Dual-Coil Design – Supports High-Frequency Switching (up to 1 Hz):Each relay has a dual-coil structure, enabling independent NO/NC control and supporting switching up to 1 time per second, suitable for fast-response control tasks.
Input Compatible with Sinking/Sourcing – Flexible Wiring:Digital inputs support both sinking (NPN) and sourcing (PNP) configurations, compatible with various sensors like proximity switches, photoelectric sensors, and push buttons.
Plug-and-Play Installation – Easy Setup:Mounts directly to the right of the CPU, powered via backplane bus, no external power required. Removable terminal blocks simplify wiring and maintenance.
