PNP Transistor Output Expansion Module for S7-200 SMART:Model DQ16, a 16-channel PNP (sourcing) digital output module in the SIMATIC S7-200 SMART series—designed for applications requiring PNP-type outputs to interface with NPN-input devices or negative-logic control systems.
16 PNP Sourcing Transistor Outputs:All 16 channels are 24 V DC PNP (sourcing) outputs, with a maximum load current of 0.5 A per channel.The common terminal (COM) connects to +24 V DC, and the output terminal sources current—ideal for driving relays, solenoid valves, indicator lamps, and NPN-input devices.
Supports High-Speed Pulse Output (PTO/PWM):Up to 6 channels support high-speed pulse output at frequencies up to 100 kHz.Supports PTO (Pulse Train Output) and PWM (Pulse Width Modulation) modes—suitable for stepper/servo motor control, speed regulation, or dimming applications.
Highly Expandable & Flexible Configuration:Compatible with S7-200 SMART CPUs (e.g., SR20, ST30, ST40, ST60).Up to 8 expansion modules can be connected—enables scalable system design for medium-scale automation.
Galvanic Isolation for Enhanced Reliability:Provides electrical isolation between output circuits and PLC logic—protects the CPU from voltage surges or load feedback, improving system safety and stability.
