8-Point High-Speed Transistor Digital Output (DQ):Provides 8 channels of 24V DC digital outputs with sourcing (PNP) transistor outputs, offering fast response times—ideal for high-frequency switching and pulse-based applications.
Supports High-Speed PTO and PWM Functions:All output channels support high-speed pulse output (PTO) and pulse width modulation (PWM), enabling control of stepper/servo motors or power regulation for actuators like proportional valves and heaters.
High Load Driving Capability:Each output can handle up to 0.5 A per point, with a maximum common terminal current of 4 A, capable of directly driving relays, solenoid valves, indicator lamps, and other common industrial loads.
Channel Grouping with Electrical Isolation:Outputs are divided into two groups (4 points each) with group-based electrical isolation, reducing cross-interference and enhancing system reliability.
LED Status Indicators per Channel:Each output channel features an individual LED to indicate ON/OFF status in real time, facilitating on-site commissioning, monitoring, and troubleshooting.
Plug-and-Play with Auto-Detection:The module connects directly to the right side of the S7-1200 CPU or expansion module via the backplane bus and is automatically recognized in TIA Portal upon power-up—no manual hardware configuration required.
