8-Channel Relay Outputs with High Load Capacity:Features 8 independent relay outputs, each capable of switching up to 2A at 250V AC or 30V DC, ideal for directly driving contactors, solenoids, lamps, and small motors.
Relay Contacts Support Both AC and DC Loads:Dry contact outputs are polarity-free, making them compatible with AC and DC loads, offering high flexibility for diverse applications.
Galvanic Isolation for Enhanced Safety:Provides electrical isolation between field circuits and logic side, protecting the CPU from surges and noise, ensuring stable operation.
LED Indicators for Real-Time Status & Diagnostics:Each output has a green LED to show active status; power and module status LEDs enable quick visual troubleshooting and commissioning.
Plug-and-Play Installation & Easy Mounting:Connects directly to the CPU via integrated bus connector; DIN-rail mounting saves space and simplifies panel layout.
