DIN-rail relay and digital input module for Home Assistant and ESPHome. Three SPDT dry-contact relays rated 3 A at 250 V AC per channel and four IEC 61131-2 compliant 24 V digital inputs for wall buttons, door contacts and auxiliary contacts. Modbus RTU slave on RS-485, configured over USB-C from a browser. Input-to-relay mapping and press logic run on the module and keep working when the controller is unavailable.

DIN-rail analog I/O module for Home Assistant and ESPHome. Four 0-10 V analog inputs on a 16-bit ADS1115, two 0-10 V analog outputs on a 12-bit DAC, and two PT100/PT1000 RTD channels on a MAX31865 with 2-, 3- and 4-wire support. 4-20 mA transmitters are read through an external 500 ohm 0.1 % shunt across a 0-10 V input; the module does not take 4-20 mA directly. Modbus RTU slave on RS-485, configured over USB-C from a browser.
