720243 SENT Monitor Module
The Yokogawa 720243 is a SENT monitor module designed for decoding and analyzing automotive sensor signals based on the SAE J2716 standard. With up to eight multiplexed channels, it provides a dependable solution for evaluating modern automotive sensor systems.
- High-Speed SENT Decoding: Supports SAE J2716 SENT protocol with fast-channel, slow-channel, status/communication nibble, and error data monitoring for comprehensive sensor analysis.
- Dual Isolated Inputs: Two isolated SENT input ports support accurate signal capture without ground interference, providing a stable interface for automotive sensor evaluation.
- Fast-Channel Multiplexing: Enables up to eight channels through fast-channel multiplexing, with additional support for slow-channel and communication data for complete system validation.
- Robust Input Protection: Handles up to 42 V input and includes built-in LED indication for valid signal detection and overdrive conditions, ensuring safe and reliable operation.
