HT PB400 – Processor Board


The NSE PB400HT is a highly versatile processor board for demanding high temperature applications. Its layout is targeted for downhole wireline and drilling tools or other industrial applications where high temperature may occur.

The processor board can communicate using CANbus and UART interface allowing for connection to a wide range of peripheral units. Analog inputs for bridge sensors (pressure sensors, strain sensors and accelerometers), RTD, single ended voltage measurement and magnetometer (typical MAG610/614) means that it can be used to monitor the most common sensors one would meet in its typical environment

The PB400 has Open Drain channels that facilitate switching of relays, solenoids or other control units. The Open Drain channels will also measure the current for each channel. It can also be configured for PWM control. Advanced monitoring and fault detection can easily be set up. There are also four general purpose pins that can either be configured as GPIO or single ended analog inputs.

The board has an embedded memory that allow for logging of key data. Default the PB400 is installed with a FRAM memory but an optional Flash memory can be installed if larger memory size is required.

The PB400 is delivered in an aluminum chassis and is designed to operate in a very high shock and vibration environment.
