Key benefits - Clear status feedback with a dedicated power indicator and TTL signal output indicator for easy monitoring. - Flexible output options combining digital and analog signals to suit control and measurement needs. Core features - High quality double panel design that supports reliable operation in sensor and control applications. - DO switch signal output (TTL) and analog AO signal output provide both digital control and analog measurement. - High and low level TTL outputs deliver direct compatibility with microcontrollers and relay modules without additional buffering. - Analog output voltage tracks concentration, enabling immediate readouts with a fast response and rapid recovery. Compatibility and performance - TTL level outputs are designed for direct connection to common microcontrollers and relay modules, simplifying integration. - The analog AO output responds to concentration changes, giving you a straightforward signal for data acquisition and process monitoring. - The device emphasizes fast response and quick recovery to support real-time control and measurement applications. Use scenarios - Microcontroller-based sensor system: use the TTL DO output to drive a control loop and read the AO analog signal with an ADC for concentration monitoring. - Laboratory instrumentation: connect the TTL high/low outputs to a controller or relay module while using the AO output to log concentration data during experiments. - Process automation: integrate with PLC or MCU-based automation where the DO signal triggers equipment and the AO signal provides continuous concentration feedback for closed-loop control. Notes - The product maintains a robust double panel design with clear indicators to facilitate troubleshooting and status verification. - No additional components are required for direct TTL-compatible connections to typical microcontrollers or relay modules.
