Yokogawa 720243 SENT Monitor Module

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.
