The Yokogawa 720243 SENT Monitor Module decodes and analyzes Single Edge Nibble Transmission (SENT) signals in accordance with SAE J2716 standard. This specialized module enables real-time monitoring of automotive sensor data across fast-channel, slow-channel, status/communication nibble, and error information, supporting up to eight channels through fast-channel multiplexing.
Technical Specifications
• Protocol: SAE J2716 SENT
• Input Ports: Two isolated SENT inputs with BNC connectors
• Maximum Input Voltage: 42 V
• Sample Rate: 100 kS/s
• Data Resolution: 11 data bits
• Signal Detection: LED indication for valid signals and overdrive conditions
• Input Isolation: Dual isolated inputs prevent ground loops and ground interference
– Key Features
• Decodes and displays physical quantities from SENT output sensors including fast-channel, slow-channel, status/communication nibble, and error data
• Eight-channel multiplexing capability via fast-channel configuration
• Isolated BNC connectors rated to 42 V with built-in overdrive protection
• Enables trend monitoring of decoded SENT data as analog waveform output
• Supports complete ECU and powertrain system validation
– Typical Applications
• ECU and powertrain dynamic analysis through multi-channel data recording
• Sensor data validation for SENT communication monitoring between airflow sensors and ECUs
• System validation and integration testing in automotive development environments
• Production equipment configuration for SENT signal monitoring and diagnostics
– Compatibility & Integration
The 720243 module operates with Yokogawa DL850V, DL850EV, DL350, and DL950 ScopeCorder Vehicle Editions. When used with DL350, the -VE (vehicle edition) option is required. Firmware version 4.00 or later is necessary for DL850E/EV and DL850/V hosts. The module is not compatible with the SL1000 platform.
