## Overview
11+
12+
This is a DIN mounted PLC-style ESP32 unit with 24V supply, OLED display, RS485, up to 8x 24V digital inputs, up to 6x 4-20mA analogue inputs, up to 6x 0-10V analogue inputs, up to 8x open collector outputs, or up to 6x 5A relay outputs (depending on the model).
13+
There are expansion modules that operate via i2c to provide more inputs or outputs.
14+
15+
The example below is for the 4-20mA current input version, with an attached 8x relay output module.
