Overview

The RPIZCT4V3T1 is a great all round and self contained unit. It can be configured to read both single phase and 3 phase systems.

Several temperature sensors can be interfaces. It is made to host a user provided Raspberrypi zero.

Future enhancement will feature mezzanine stack for additional sensor capacity.

An enclosure solution is proposed using aluminium extruded case.
