Sequent Microsystems RTD Data Acquisition 8-Layer Stackable HAT for Raspberry Pi

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 le
