Description
Sequent Microsystems RTD Data Acquisition 8-Layer Stackable HAT
Designed for Raspberry Pi (Not included)
Eight layer stackable to 64 RTD channels
RS485/MODBUS transceiver
Programmable threshold LEDs on all inputs
Pluggable Connectors 26-16 AWG wires
The Sequent Microsystems RTD Data Acquisition 8-Layer Stackable HAT for Raspberry Pi is compatible with all Raspberry Pi versions from Zero to 4, the RTD Data Acquisition Card offers a compact and inexpensive solution for reading and storing data from up to 64 RTD-100 temperature sensors. Using 24 bit delta-sigma A/D converters with four channels each, the card achieves better than 0.1% accuracy. Field calibration with a precision 100Ω resistor can lead to 0.01% precision.
Since temperature measurement using RTD is based on resistance, the resistance in the lead wires and connectors must be taken into account when calculating the overall resistance in the system circuit. Using a 3-wire circuit design allows lead wire resistance to be factored out of the overall calculation.
The card is compatible with all Raspberry Pi versions from Zero to 4. It shares the I2C bus using only two of the Raspberry Pi’s GPIO pins to manage all eight cards. This feature leaves the remaining 24 GPIOs available for the user.
The RTD Data Acquisition card needs 5V to operate and can be powered from Raspberry Pi or from it's own pluggable connector. The cards needs 50mA to operate. Up to eight RTD Data Acquisition cards can be stacked on your Raspberry Pi. Each card is identified by jumpers you install to indicate the level in the stack. Cards can be installed in any order.
