8-Channel Transistor Source-Type Outputs with Fast Response:Features PNP (source-type) transistor outputs, each capable of delivering up to 0.5A at 24V DC, with switching time < 1ms – ideal for high-speed control applications.
Optimized for DC Loads with Strong Drive Capability:Designed for 24V DC loads such as relays, solenoid valves, indicator lamps, and input modules of other devices – widely used in industrial automation.
High Switching Frequency for Pulse Control Applications:Supports switching frequencies over 100 Hz, suitable for PWM signals or periodic on/off control tasks (e.g., flashing lights, timed actuators).
Compact Design Saves Space:Occupies only one slot on the S7-300 rack, making it ideal for compact control cabinet installations.
LED Indicators for Real-Time Status Monitoring & Diagnostics:Each channel has a green LED to show output status, enabling fast visual troubleshooting and commissioning.
Plug-and-Play Installation:Uses standard front connectors (e.g., 6ES7392-1BJ00-0AA0), allowing easy wiring and quick module replacement with minimal downtime.
