2. Key Selling Points8-Channel Switchable Transistor Outputs (Sourcing/NPN or
Sinking/PNP):Provides 8 channels of 24V DC digital outputs, each可 be configured via jumper as either sourcing (PNP) or sinking (NPN) output—offering maximum compatibility with various field devices
and control systems. Supports High-Speed PTO & PWM Functions:All 8 outputs support high-speed Pulse Train Output (PTO) and PWM (Pulse Width Modulation) with frequencies up to 100 kHz, ideal for stepper/servo motor control, direction/enable signals,
and frequency simulation. Ultra-Fast Response for Precise Control:Extremely fast switching times: ON < 0.2 ms, OFF < 0.4 ms, enabling precise and responsive control of actuators in
high-speed automation systems. Individually Configurable Channels:Each output can be independently set in TIA Portal as standard output, PTO, or PWM mode—providing high flexibility
for multi-functional applications. Individual LED Status Indicators per Channel:Each output channel features a dedicated green LED indicator for real-time ON/OFF status display—facilitating commissioning,
monitoring, and troubleshooting. Plug-and-Play with Auto-Recognition:Mounts directly to the right of the S7-1200 CPU via the backplane
bus and is automatically detected by TIA Portal upon power-up—no manual addressing required.
