Like everything I have bought from Sequent, the Industrial Automation HAT just works. When I came across a weird thing with a sensor I was trying to use I hit up the chat at 8:30PM, sure enough they were right there to get me fixed up. Great products, and even better support.ld trust with potential customers.

I bought the Sixteen Solid State Relays for Raspberry Pi and I was up and running in less than one hour! After installing Node-Red on Raspberry Pi 4B, I followed the direction provided here and added the pallet for this relay PCB. In less than a few minutes the flow was enabling and disabling the relays. Couldnot havebeen any easier.

The Sequent Microsystems RTD board is a good device to use for my project. Having the python and NodeRed node definitions to allow easy programming to access the data. I also had an excellent response from Sequent Microsystems to any questions or issues I had with using this product.

I have used this for automating a brewery cellar system (24 fermenters) using this card, the relay card and Node Red. Support has been fantastic with a small change I requested done in a matter of days. I also like that the RTD's can be calibrated. Other systems I've looked at have cost tens of thousands of $$ whereas this solution does the same for way under a grand.

Connecting Raspberry Pi to the real world

Sequent Microsystems designs and manufactures I/O Cards for Raspberry Pi. We expand the capabilities of Raspberry Pi with analog inputs and outputs (0-3.3V, 0-10V, 4-20mA), optically isolated inputs from 3 to 240V AC or DC, 2 to 16 on-board relays and solid state outputs, event counters, quadrature encoders, 1K/10K thermistors, all types of Thermocouples, PT100 and PT1000 RTD sensor inputs, Real Time Clock with battery backup, RS485/MODBUS, RS232, RS422, M-BUS, 1-Wire and CAN communication, MOSFET and TRIAC load drivers. All our cards use only the I2C port for communicating with Raspberry Pi, leaving all the GPIO pins available for other tasks. Three Sequent cards (Home, Building and Industrial Automation) are "Swiss Army Knife" types, packing all the possible functions in the available space. If extra functionality is desired, each card can be stacked up to eight levels. Additional universal inputs, relays or solid state outputs can be added using compatible cards. Up to eight cards of each type can be installed in any combination on a single Raspberry Pi. Custom inquiries welcomed.
